Safety GIS Workshop
Augusta A & B

Led by Robert Pollack (FHWA, Office of Safety) and Eric Green (KY Transportation Center): FHWAs Highway Safety Improvement Program (HSIP) and related legislation requires that States collect the Model Inventory of Roadway Elements Fundamental Elements (MIRE FDE). These 37 Elements, a common base map, and a handful of crash elements are the minimum required to perform network screening on all public roads. The State Safety Data Systems (SSDS) Guidance prioritizes the process as:

1) Common Base Map
2) Locatable Crash Elements
3) Collection and Integration of MIRE FDE
4) Safety Analysis on All Public Roads

This workshop will demonstrate noteworthy practices States, Academics, and Consultants have made in meeting the SSDS Guidance.

8:00 AM  –  12:00 PM
GIS Management Workshop

FHWA HPMS Reassessment
Royal Dublin A & B
Led by Tom Roff (FHWA): FHWAs Highway Office of Highway Policy Information (HPPI) is developing system requirements for the next version Highway Performance Monitoring System (HPMS v 9.0). Based on the Reassessment Research last year, the next version is focused on modernizing the program featuring incremental updates, use of third party sources, providing a framework for safety data (Model Inventory of Road Elements- MIRE). Version 9.0 will require a more spatial approach to managing the HPMS program. This workshop will focus on ideas from the spatial community as we work toward making this transition.

1:00 PM  –  5:00 PM
Asset Management and CIM/BIM
Augusta A & B
Led by Allen Ibaugh, AICP, GISP: CEO of DTS and Jason Amadori, GISP: Principal Business Development Director: Acquisition (CIM/BIM/LIDAR/DRONE, etc.), management system components (condition, risk, work management) and business intelligence (budget forecasting/performance). Public and private agencies face continuous challenges to accomplish more with less as increases in demand, regulatory requirements, infrastructure deterioration, and political and economic forces have significantly outpaced increases in capital and operating budgets. Many of these agencies are turning to Asset Management to cope with these challenges and improve business performance and effectiveness. This workshop will focus on several aspects of developing an asset management program that could help improve performance, reduce long-term costs, and maximize return on investment in infrastructure assets. Specific topics include data acquisition (CIM/BIM/LIDAR/DRONE, etc.), management system components (condition, risk, work management) and business intelligence (budget forecasting/performance).
1:00 PM  –  5:00 PM
Applications of Enterprise GIS-T, (AEGIST) FHWAs approach for a National transportation network
Royal Melbourne A & B
Led by Al Butler (VHB), Bob Scopatz (VHB) and Joe Hausman (FHWA): This workshop presents the new FHWA – AEGIST Guidebook that is being developed as GIS/LRS guidance to support business rules, data structure, geometric features, data maintenance, data publication, and organizational structure for the Nation’s Transportation Community. This guide is focused on highway networks while encompassing a multimodal vision, describing a National transportation network that also meets the needs the Nation’s transportation community at all jurisdictional levels. The Guidebook will show how to leverage an original source database that is either a set of intersection-to-intersection topological segments (denormalized view) or a set of LRM inventory routes (normalized view) to create a network that brings us together as a Nation.
1:00 PM  –  5:00 PM
CTPP Workshop on the Maps and Data
Congressional A & B
Led By Penelope Weinberger (AASHTO Data Manager) and Dany Bouchard (President, CartoVista): The Census Transportation Planning Products (CTPP) Program crash course is a shortened version of our full on training, tailored to be delivered in a few hours (or less), it’s a content filled, action packed, introduction to the data and the issues and opportunities associated with it. With most states participating in the CTPP, an AASHTO technical service program, this is a robust program of data, technical assistance, training, outreach, and research. The workshop is led by CTPP experts with many years of program experience. The workshop will be thought provoking, entertaining, and ultimately extremely useful to the practitioner.  The Data Access Software includes some robust GIS / Web Mapping features for both geography selection and rendering of results, including both excellent visualization processing and statistical and thematic analyses, at a high level of performance. Along with ASCII and EXCEL formats, the data can also be downloaded in .tab and .shp files. The CTPP received new data and new mapping software in 2018, most practitioners have not yet seen the data from the CTPP based on 2012 – 2016 data, nor the new HTML5 based interactive maps.  With a ton of new data and tools, this is not the same crash course as before! Come and learn how CTPP fits in to your planning and analysis toolkit, from generating demographic profiles and smart maps to populating your forecast model and developing your long-range plan.

Statewide Parcels for Right-of-Way Planning
Royal Dublin A & B
“Parcel data in Vermont is currently incomplete, inconsistent in content, and varies in age from one town to another. Incomplete and inconsistent data lead to less efficient performance on the part of some state employees and prevent others from performing certain analyses and tasks. Data produced by this project will allow state programs, municipalities, and private sector organizations to perform essential mapping and analysis activities that support a vibrant economy as well as efficient and effective government. Led by the Vermont Agency of Transportation (VTrans), and supported by 8 other state agencies and the Federal Highway Administration the State of Vermont has undertaken an ambitious project to create a statewide parcels layer for the 255 municipalities throughout Vermont. This presentation will look at the successful multi-agency collaboration, as well as the challenges that needed to be overcome in a small, rural New England state to ensure a successful, standardized parcel data set, which will be used by VTrans for Transportation Right-of-Way planning.”

A Preliminary Identification of At-Risk Roadways Due to Elevated Groundwater from Sea Level Rise
Royal Dublin A & B
“The effects of sea level rise on transportation infrastructure in Florida’s coastal areas have already become apparent. Fair-weather flooding of streets during “king tides” has become a common occurrence in the City of Miami Beach. According to current projections, similar overtopping of state roadways by coastal flooding on mainland Miami-Dade County is decades away. However, long before the roadway surface is inundated the roadway base may be compromised by elevated groundwater levels. In 2016, Florida DOT District Six sought to identify which state roads were at risk of violating the Roadway Base Clearance standards set out in the FDOT Flexible Pavement Design Manual based on a projected future Design High Water (DHW) elevation of 1.0 feet NAVD88. A GIS-based screening analysis using recent 10-foot resolution LIDAR-derived Digital Elevation Model (DEM) data was conducted for all state roadways in the part of Miami-Dade County that fell within the zone of tidal influence east of the Salinity Control Line. A total of 41.1 miles (28.4%) of the 144.6 miles of state roads within this area were identified as being at-risk for not meeting the FDOT DHW base clearance criteria under the chosen future groundwater elevation scenario. In 2018, the same GIS screening technique was applied to US-1 through the Florida Keys, mainland Monroe County and southern Miami-Dade County using a 10-foot resolution LIDAR-derived DEM. The analysis found that 57.2 miles (41%) of the total 138.3 miles of US-1 in that region was at-risk of DHW base clearance issues, assuming a future groundwater elevation of 1.6 feet NAVD88. An ArcGIS Online “swipe map” was developed to allow side-by-side comparison of the two scenarios, in addition to the static map series provided in the final report. These preliminary results provided the FDOT with specific sections of roadway to analyze in greater detail with the aim of guiding future roadway planning and design decisions. “

New GIS Approach to Managing Signs
Royal Dublin A & B
“A dense urban environment often means that roadway signage is also very dense and information-rich. Historically, DC’s Department of Transportation (DDOT) has struggled to manage this vast inventory of signs in an efficient manner. This project describes a unique data collection approach with an equally unique strategy to help manage the traffic signage in Washington, DC.DDOT contracted with Cyclomedia to capture all of the traffic signage within the District. A rather unusual aspect of this data collection was that it was done completely in-office, utilizing Cyclomedia street-level imagery in a Web browser. Using this imagery, Cyclomedia was able to extract high-precision GIS points for the signs and supports, delivering the data to DDOT within 4 months.Simply mapping this detailed GIS sign inventory is helpful to know the location of signage but not enough to effectively manage the sign inventory. DDOT built a custom, GIS-based Web application to assist with the complicated editing and request workflows which make sign inventory management a difficult operation. One additional perk: all the signs are continually referenced against DDOT’s linear referencing system (LRS).Beyond attaining a smoother asset management practice, the payoff really begins to show when you see what you can do with this awesome sign data. Ever wanted to automate the extraction of speed limit and parking information from your linear referencing system? We’ll show you how we did it in this session.”

DOT Data Models – a Deep Dive
Royal Melbourne A & B
“This presentation will dive deeply into data models using Esri geodatabase terminology and UML notation. Several geodatabase data model schemas will be explored and diagrammed, including MIRE 1.0, HPMS, MMUCC, the Esri RH Min Schema, Kansas DOT, and other state transportation agencies. This information should lead to some discussion about data model planning, design, maintenance, deployment and interchangeability, and a better understanding of the challenges and opportunities associated with development of a robust “”standard”” transportation database model for the United States. “

Roads and Highways Performance Improvements
Royal Melbourne A & B
“This presentation will focus on performance improvements for the Roads and Highways (R&H) environment. When initially implementing, R&H can be small and not necessarily complex (reserved comment). Adding CTE, Services, and some custom tools, the R&H system overall starts becoming taxed. Any performance gains help, even marginal, seemingly insignificant changes. Though primarily focused on the SDE geodatabase and the RDBMS, there will be insights given for data management, Services, WMX, Data Reviewer, and how they all relate.”

The 3D Elevation Program (3DEP) and Transportation Infrastructure
Congressional A & B
“The use of 3D light detection and ranging (lidar) elevation data in infrastructure construction and improvement projects provides significant productivity, safety, and cost-saving benefits. The sizeable need for improvements to the Nation’s transportation systems and other infrastructure calls for an efficient, systematic approach to acquiring foundational 3D elevation data. The 3D Elevation Program (3DEP) is accelerating the rate of high-quality 3D elevation data collection for the Nation to address a wide range of critical needs. The program, managed by the USGS, presents a unique opportunity for collaboration between all levels of government to leverage the services and expertise of private sector mapping firms that acquire the data. The program began in 2016 with the goal to complete national coverage of 3D elevation data in 8 years. Today, over 50 percent of the Nation has 3DEP-quality data available or in progress. The lidar point cloud data (a different technology called IfSAR is used in Alaska) and derivative elevation products and services are distributed to the public through The National Map. The presentation will provide a status of the program, highlight available products and services, and explain the process by which attendees can apply for partnership funding to support the acquisition of lidar data over specific geographic areas in the pursuit of national coverage. Also included are example applications for lidar data in the transportation and infrastructure sector.”

Northern Exposure! The awesomeness of managing the Minnesota DOT’s statewide LRS
Augusta A & B
“When you get down to it, the most important GIS layer for a Department of Transportation is the roadway layer. Asking a DOT to manage their roadways and assets without this layer is like asking a baker to make a tasty treat without the dough. However, it is a large task, especially in Minnesota, where all roadways are managed within the LRS. This presentation will discuss the day to day management of the MnDOT LRS. Specifically, this presentation will cover the current update process, training, best practices and techniques to monitor the editing process in conjunction with ESRI’s Roads and Highways, Roadway Characteristics Editor (RCE), Workflow Manager and Data Reviewer extensions. This presentation is perfect for novice and seasoned LRS aficionados alike but will also be interesting for any GIS managers. The goal of this presentation is to share information and illicit dialog to learn from each other and make our processes and data products the best they can be.”

Lessons Learned in LRS Migration – NMDOT’s ARNOLD Project
Augusta A & B
“NMDOT recently completed the second stage of a multi-phase project with the overall goal of implementing a linear referencing system that will satisfy FHWA’s ARNOLD requirements. Phase 1, completed in 2016, focused on the collection and development of an initial road network from multiple data providers. Phase 2, completed in August of 2018, involved the cleanup, migration, and calibration of the initial network, and system implementation tasks to establish Esri’s Roads and Highways Linear Referencing System as the new system of record for the DOT. The new RIS (Roadway Inventory System) now serves as the foundation and integration point for other systems including Road Inventory, HPMS reporting, Traffic, and other external business systems This presentation provides an overview of the project, technical approaches, and lessons learned during the execution of the project.”

Building a sustainable data migration workflow using FME!
Royal Dublin A & B
“Many transportation agencies are struggling with the decision to maintain spatial data in CAD, GIS, or more recently BIM. The Minneapolis St-Paul airport (MSP) is managed and run by the Metropolitan Airports Commission (MAC) which is solving this dilemma through a series of well documented and technically advanced workflows and business processes. Interior, airfield, landside, and utility data are updated by both selected consultants and MAC staff in the CAD environment. MAC has applied best practices in data governance to develop standards which enable an automated CAD data translation to geodatabase format using Safe Software’s Feature Manipulation Engine (FME). FME is also used to check the data as it is processed and to create metrics to help monitor MAC’s commitment to continuously improving its data. Resulting GIS data is then used to support data analysis and visualization. This repeatable process allows the data owners to perform updates in software most suited to their work, which results in quick process adoption and subsequent GIS data publication. This presentation will walk attendees through data preparation, documentation, the development of FME workbenches, data validation procedures implemented, along with lessons learned.”

Integrated Information Systems for the Transportation Infrastructure Life-cycle
Royal Dublin A & B
“The long standing goal among many infrastructure professionals has been the ability to have a fully integrated information flow through all stages of the project life-cycle. In the past, the disparate software systems have made this process difficult, if not impossible. But pressure from the industry has led to greater inter-operability developments, drawing closer to the ability to capture the benefits of a whole life-cycle information management process.This presentation will focus on how GIS and CAD and BIM are moving towards greater inter-operability and mutual support for transportation professionals. Leading edge examples from several DOTs will be highlighted, as well as a view to the future.”

Back on Track: Giving a State Rail Agency’s GIS Data the Green Signal
Royal Dublin A & B
“The Virginia Department of Rail and Public Transportation’s (DRPT) Division of Rail Planning identified the need for a unified and up-to-date GIS rail infrastructure database for the Commonwealth of Virginia. Since 1995, several studies produced by DRPT, the Federal Railroad Administration (FRA), and other states/entities have addressed issues relating to rail corridor development for both freight and passenger services in Virginia. Many of these studies involve overlapping portions of the rail network. In addition, various GIS mapping exercises, conducted by DRPT staff as well as through consultant services, have been performed for a variety of needs and purposes in support of rail data analysis and presentation. DRPT’s legacy GIS data varied in quality and integrity, specifically in terms of spatial accuracy and attribute information; primary datasets were consistently lacking spatial and tabular completeness. Rather than trying to merge schemas from the incomplete legacy layers, the team used the FRA’s 100K Rail Network schema as the template, so the Virginia dataset would be compatible with the national and other state databases. This process involved a manual QA/QC process, including updating the spatial accuracy of each rail line through manual manipulation, using the most recent aerial imagery as a reference. The attribute information from the legacy DRPT layers and the FRA 100k Rail Network were consolidated into and attribute table structured from the FRA schema. This provided the primary “Rail Lines” feature class of the database with information inclusive of ownership, trackage rights, subdivision, signaling system type, weight limits, and height limits. The database was also populated with additional publicly-available rail infrastructure layers, including passenger stations, tunnels, bridges, switches, mileposts, crossings, and other miscellaneous layers that DRPT will use for analysis and future projects. This comprehensively remodeled, statewide rail geodatabase is now publically available through ArcGIS Online. The creation of this new geodatabase will foster inter-agency coordination and is intended for use by internal, external, and pubic-reaching entities to serve as the authoritative database of all rail infrastructure within Virginia.”

This Ain’t Our First Rodeo: Progress and Innovation in Emergency Response Mapping
Royal Melbourne A & B
In October, Hurricane Florence threatened to pummel coastal regions of South Carolina. During a press conference in which Gov. McMaster was advising the public on preparedness actions to take he assured citizens that “this ain’t our first rodeo.” He was referencing a series of major weather events the state has dealt with dating back to 2015 with a 1000-year rain event that delivered debilitating impacts. In the aftermath as the SCDOT responded, the GIS/mapping department recognized several areas to assist the agency, including creating a map of all road closures on state maintained roads instead of a pdf list. Data requests poured into the office. We struggled to respond efficiently and enacted an “all hands on deck” approach to get data out as timely as possible. SCDOT GIS knew this wasn’t sustainable and began creating more efficient processes for the future. Unfortunately every year since, we have had a major weather event. Each event taught something new and provided the opportunity to grow and provide more dependable, insightful data to a wider audience. SCDOT is now a finely tuned machine able to deliver data to the public seamlessly through an AGOL site that includes information on evacuation routes, lane reversals and road closures, supporting the agency and the public during every stage of the event. We have worked with commercial routing providers in communicating the road condition data through applications that are already at the public’s fingertips. Automating the delivery of road condition information to the point of ‘hands off’ phase allowed GIS/Mapping office to allocate more resources toward better support of external and internal customers. We are working closely with the SCDOT hydrologists to enable cataloging, viewing and analysis of critical locations, historically flooded assets, and other internal and external data. Most recently, we have created a collector application to allow for real time display and analysis of field collected data. Perhaps our most important accomplishment is we have been able to shift our approach to hazardous weather events from frenzied and reactive to innovative and proactive. This has shown benefits throughout the agency such as faster response time to public inquiries, reduced staffing during emergencies and higher level decision making. This presentation will take you through lessons learned, what works, what doesn’t, and what is to come in the future as we prepare to face more severe weather events.

Road Inventory Submission Application for Local Data
Augusta A & B
“The Road Inventory Submission Application (RISA) is an interactive web portal designed to replace the process of updating road data by using archaic New Road Entry Forms. Previously, updates were sent via mail or email after a municipal employee completed a worksheet describing road characteristics, the generation and processing of which was reportedly counterintuitive. MassDOT GIS has identified and developed solutions for three primary workflows; adding a new road, updating existing road characteristics, and adjusting the layouts of existing road geometries. The online interface is compatible with Esri’s Roads & Highways product and the linear referencing structure of the MassDOT GIS road inventory. “

Custom M-Value Tool and Conversion of Legacy Tools for ArcGIS Pro
Augusta A & B
“ArcGIS Pro does not have a built-in tool for setting m values on polylines. This poses a serious obstacle for DOTs that perform linear referencing to adopt ArcGIS Pro in favor of ArcMap.Using ArcGIS Pro SDK for Microsoft .NET we created an add-in that will apply measures to our roadway polylines for linear referencing. We take advantage of the extension assemblies to use the geoprocessing tools provided by Esri, specifically the Create Routes geoprocessing tool within the Linear Referencing toolbox. We use this geoprocessing tool to create a new polyline with m values applied in a temporary geodatabase, and then copy the geometry (including m values) back to our roadway polyline. Overcoming this crucial hurdle has enabled us to begin converting our existing custom tools, originally developed in ArcMap for QA/QC of geometry and attribute edits, over to ArcGIS Pro, in order to utilize the “tasks” functionality in ArcGIS Pro to control and constrain the editing workflow for QA/QC purposes.In this presentation, we share how we created and implemented the custom measure tool, how to transition custom legacy tools from ArcMap to ArcGIS Pro, and how using tasks in Pro can help ensure data quality.”

As state agency IT enterprise GIS team, we are deeply involved in all aspects of transportation GIS data acquisition, management, visualization, and application development.Rapid advancement in computing resource and GIS technology allows us to create real time dynamic applications to server state transportation needs in policy making and day to day operations.In this presentation, we would like to present a number of our recent mission critical GIS projects to demonstrate the utility of modern geospatial database, ESRI Roads and Highways linear referencing, service oriented application development framework.Previously, our infrastructure project utilized a combination of ESRI SDE and Oracle database. In the GPAS project GDOT developed an enterprise system for signal, access, and utility permitting. GDOT synchronized user permit locations with associated assets/preset/operation data in a single Oracle geo-spatial database. This greatly streamlined the permitting process and simplified data maintenance. In our suite of enterprise applications, GDOT incorporates the ESRI roads and highways linear referencing capability to allow fast and easy access to auxiliary reference data at varying levels of details, enabling differential data access by various decision makers and clients. The ESRI linear referencing function is wrapped in an independent module that provides customized Application Programming Interface (API), which can be imported into different applications and used as a service.The presentation will conclude with discussion and outlook about the use of GIS Data and technology in GDOT.”

Bringing the power of 3D Mapping to every GIS user, with no effort
Royal Melbourne A & B
3D data is being collected by DoTs on a massive scale, but is often locked up in the designing / construction department with a few engineers having access to it, if any. This data however is so valuable that I am convinced every GIS user in a DoT does have great advantage in using this data, however a bit complex, but highly valuable and available. Just make it simple. A proper and up to date 3D map becomes more essential than a 2D maps has ever been. How do we assemble, manage, diversify this content, and how to we bring this to the daily workflows within every DoT’s organisation.

Florida Motor Carrier Size and Weight (MCSAW) Asset Inventory and Management
Royal Dublin A & B
The Florida Department of Transportation, Motor Carrier Size and Weights Division (MCSAW) is developing their vision of the future for their Interstate Weigh Stations. These Twenty (20) facilities range in age from 25 to 30 years old and are located throughout the State of Florida. FDOT turned to a strategic asset management approach to help inform and drive a new capital initiative to transform Florida’s freight support system into the system of the future. The first step in developing the Vision was to identify and inventory all Weigh Station assets, attributes and features and to assess their condition, so that any improvement programs could be based on existing facilities and conditions. In preparation for the inventory, geo-location, and condition assessments, a data dictionary listing all known assets attributes and features was developed based on visual observations, record drawings and LIDAR readings that were available from two weigh stations. This dictionary was used to pre-populate the Mobile Devices to facilitate efficient and paperless data collection and ratings. MCSAW selected the five-level rating scheme; excellent-5, good-4, fair-3, poor-2, failed-1 to be used to rate the condition of assets at their weigh stations, and that the entire inventory and condition assessment would be conducted electronically using mobile data collection devices. It was further determined that the five (5) level rating scheme condition criteria should be closely aligned with the Maintenance Rating Program and Uniform Inspection Handbook for off road facilities to the extent possible. It was decided that both Condition Assessments and Maintenance Ratings would be captured during the inspections. Once completed, MCSAW will have a detailed record of all assets, their condition, and a measure of the maintenance level being provided at the Weigh Stations. Based on the success of this effort, further Asset Inventory and Condition Assessments may be conducted on other transportation facilities. These objective assessments will be used to model current and future conditions to allow modeling of necessary capital improvements and desired design scenarios for the facilities to support the future Vision. This asset management database will also serve to maintain accurate records going forward so that future condition assessments can be conducted efficiently.

Worst-First Doesn’t Live Here Anymore – Prioritizing Infrastructure Projects through Geo-Automation
Royal Dublin A & B
“The Iowa DOT is implementing a multi-year initiative to meld data sources together, designed to help support project scoping and development prioritization. The current application of that initiative is found in their new Prioritization & Scoping Tool, creating an integrated approach for identifying, scoping and associating potential projects with the DOT’s Highway Candidates List and a prioritization process that supports capital program evaluation. Developed as a web-based application, the Tool allows DOT staff to propose potential projects (aka project scopes) and then initiates a real-time GIS-based algorithm, which determines the prioritization and complexity on all currently planned, programmed and scoped projects. To develop the algorithm for the application the DOT involved iterative, inter-department engagement that established the basis for a prioritization algorithm, as well as the critical garnering of agency consensus on how to evaluate, weight and rank all of the criteria that goes into prioritizing projects. Designed and developed with the mantra of “while it isn’t all about the tool, the right tool in the right hands can change an entire culture,” this effort has helped streamline the environmental process, inform the project purpose and need, and provided opportunities to identify issues that might impact a potential project. The Tool also calculates in real-time any potential impacts to the project by evaluating over 40 environmental, traffic, and other GIS layers. End users of the application can perform more robust filtering to compare projects to one another in order to assess the best candidate to incorporate next into their capital program. Users also can look at the most granular level of performance metrics that are contributing to priority scores of each project, noting whether a particular pattern is contributing to the need for one or more projects in a single geographic location.We invite you to discover how this important effort is changing the way that the DOT thinks about projects, and evaluates them as part of a larger program strategy. Using geospatial tools and processes have been the linchpin to this entire initiative.”

Data Economy and HPMS
Congressional A & B
“This presentation focuses on just one aspect of the recent HPMS Reassessment, to which many State DOTs contributed input for FHWA’s consideration. Specifically, we will cover the recommendation for “Data Economy,” which is the term FHWA chose for a reporting approach wherein disparate data items are consolidated into singular items and a data model is provided that accepts State DOTs submitted data in a form closer to native State DOT formats. This is will be achieved through the removal of certain calculations, aggregations, and coded values, thereby putting less burden on the states.”

Highway Performance Monitoring System Validation using 1Spatial’s 1Integrate
Congressional A & B
“The Federal Highway Administration (FHWA) is responsible for evaluating information from State DOTs, specifically the extent, usage, condition, and performance of the Nation’s highway network as explained in the Highway Performance Monitoring System (HPMS) Field Manual. To perform the evaluation, they historically have used a series of SQL scripts to validate State DOT submissions. These scripts were difficult to maintain and allowed only one State to be processed at a time. Further, the time required to evaluate submissions made reporting issues back to States an arduous process.FHWA contracted with 1Spatial Inc. to implement 1Spatial’s 1Integrate software as a replacement for the HPMS validation engine and to leverage 1Integrate’s topological and linear referencing capabilities to enhance reports provided back to State DOTs. By using the 1Integrate rules engine in combination with FHWA’s subject matter experts, FHWA is able to reduce the time required to evaluate State DOT submissions, process multiple submissions in parallel, and generate custom spatial reports that identify non-conformances in data.This presentation will highlight how FHWA is revamping their HPMS submission and validation process. It will illustrate how using topological and linear referencing functionality is enhancing the performance and accuracy of the HPMS validation process.”

The Best of Both Worlds for Asset Location
Augusta A & B
“Last October, the Michigan Department of Transportation (MDOT) went live with a GIS-centric, Transportation Asset Management System (TAMS). The goal of TAMS is to fundamentally change and improve business processes, analysis, and facilitate data-driven decisions in managing transportation assets across all levels of the Department.The TAMS solution is developed on Esri’s Roads and Highways platform with additional asset management tools from Data Transfer Solutions and data visualization and analysis tools from Transcend Spatial Solutions. Early in the design of the system, it seemed that MDOT would have to choose between storing asset data either based on the actual longitude/latitude of the asset in a feature class or linearly referencing the data as Route ID and begin/end measures as a Roads and Highways Event. As there are benefits to each method of storing the data, MDOT did not want the new system to have reduced functionality by selecting one approach over the other. Instead, MDOT worked with TSS to innovate a methodology to get the best of both worlds.This session will review how TAMS was designed to maintain both the actual and linearly referenced locations of each asset, issues that needed to be considered during the implementation, how those issues were addressed, and how the data is maintained today.”

Extending Survey123 to effectively manage PennDOT’s guiderail workflows and improve data quality
Augusta A & B
“PennDOT’s Bureau of Maintenance and Operations (BOMO) is currently developing an Esri Survey123 software solution using AppStudio for ArcGIS to collect guiderail data. Users select the guiderail asset to be surveyed from a map when guiderail repairs or replacements occur in the field. BOMO will also use Esri’s Operations Dashboard for ArcGIS to monitor in real-time the status of guiderail repairs. Currently, guiderail data capture is being done manually (or not being done at all), including the updating of guiderail inventory and condition data in the Department’s Roadway Management System (RMS). In addition, management cannot effectively monitor the overall repair and maintenance activities of guiderails at county-wide, district-wide, or state-wide levels. BOMO needs to track the end-to-end process of the guiderail repair and maintenance workflow to ensure guiderail policy compliance. It sometimes takes several months to a year or longer to identify, schedule, complete and submit for reimbursement guiderail and/or end treatments repairs, and management cannot easily identify where the bottlenecks are occurring. This presentation will demonstrate the custom Survey123 solution that will be used to solve these problems.”

Safety Rest Area Asset Management: Creating a GIS-Based Asset Management System
Augusta A & B
“Safety Rest Areas (SRAs) across the Commonwealth of Virginia pose many unique challenges from an asset management perspective. These SRAs function like small cities, with their own water, wastewater, electric, and public service assets on site. Spread across 43 SRAs, all of these assets have two things in common: they need to be inspected on a regular basis and they require maintenance activities. The tracking of those inspections and maintenance activities can be difficult to manage. In this presentation we will highlight how we implemented a fully functioning GIS-based asset management solution for the SRAs across the commonwealth. Facets of this presentation include: data modelling, field collection through ArcGIS Online, data migration, data hosting in ArcGIS Online, data maintenance/enhancement strategies, and inspection report generation from ArcGIS Online. “

Location Allocation of Sugar Beet Piling Centers using GIS and Optimization
Royal Dublin A & B
The sugar beet is one of the most important crops for both social and economic reasons, even though the area under sugar beet cultivation in the Red River valley of North Dakota and Minnesota is comparatively smaller that of corn and other crop lands. It generates a large economic activity in local and regional level with a greater impact on jobs and stimulation of agriculture, transportation, and farm economy. Sugar beet transportation takes place in two stages in Red River Valley: the first step is from farms to piling centers (pilers) and the second step from pilers to processing facilities. This study focuses on the problem of optimizing piler locations based on supply variation. Sugar beet supply and harvest varies significantly due to numerous reasons such as weather, water availability, and different maturity dates for the crop. This provides for a variable optimal harvesting time based on the plant maturity and sugar content. Sub-optimized pilers location result in the high transportation and utilization costs. The objective of this study is to minimize the sum of transportation costs to and from pilers and the pilers utilization cost. A two-step algorithm based on the geographical information system (GIS) with global optimization method is used to solve this problem.

Optimizing the HPMS Process at ALDOT
Royal Dublin A & B
“Over the last several years, the Alabama Department of Transportation (ALDOT) has undergone a full-scale modernization of the DOT’s annual HPMS submittal process, including the implementation of a new, authoritative Linear Referencing System, an enterprise geodatabase to manage key HPMS data items, and a suite of HPMS data validation tools. The result has been a dramatic change from an inefficient process to one of the best in the nation.ALDOT’s latest solution is HPMS Manager, a comprehensive suite of tools for managing and preparing the annual HPMS submittal. Using HPMS Manager, the HPMS Coordinator now can internally track progress of the submittal, manage all data item sources, perform and modify official HPMS validation rules, prepare the submittal files, and generate reports and output files identical to products of FHWA’s HPMS software. Additionally, edit functionality allows for ad-hoc editing of validation errors and the ability to save those changes back to the source layers, therefore keeping datasets synchronized and avoiding duplication.This presentation will provide an overview of how ALDOT uses HPMS Manager to administer the annual submittal process.”

Designing and Implementing a GIS-based Safety Roadway Management System for the ConnDOT
Royal Melbourne A & B
“The Highway Safety Improvement Program (HSIP) requires a data driven, strategic approach to improve highway safety on all public roads that focuses on performance. To address these requirements, the University of Connecticut (UCONN) Transportation Safety Research Center and VHB are designing and building a custom, state-of-the-art, GIS-based Roadway Safety Management System for the Connecticut Department of Transportation (CTDOT). The Roadway Safety Management system is a web-based application that provides advanced safety analysis tools for CTDOT and UCONN safety engineering staff to use in making data-driven decisions to identify roadway safety improvement projects. The UCONN/VHB Team have implemented a custom network screening engine based on the Highway Safety Manual (HSM). Screening methods include Simple Ranking, Sliding Window and Peak Searching. The team has also built out a Diagnosis Module for diagnosing crash locations. The Diagnosis module includes a Crash Mapping application that leverages the ArcGIS API for JavaScript, as well Crash Tree Mapping, Collision Diagram Mapping, Virtual Street Viewing, and Crash Statistics. The application also includes a Data Management Module to import CTDOT’s authoritative datasets (roadway network, intersection locations, etc.) configuration tools for updating Safety Performance Functions, homogenous segmentation and other key variables for use in the Roadway Safety Management System. The Roadway Safety Management System when completely built-out will implement the Federal Highway Administration’s (FHWA’s) six-step highway safety management process: network screening, diagnosis, countermeasure selection, economical appraisal, project prioritization, and countermeasure selection. The Safety Management System will implement Parts B and C from the Highway Safety Manual (HSM). Network Screening, Diagnosis and Countermeasure Selection Modules are currently available in use by CTDOT.Technology Used:.NET Core, Angular JavaScript, SQL Server, ArcGIS API for JavaScript, ArcGIS Enterprise, SQL Server Reporting Services (SSRS)”

A unique approach to extracting features from raster images
Royal Melbourne A & B
“To address a need for spatially relating historical property transactions to current state land assets, the Maryland Department of Transportation (MDOT) State Highway Administration (SHA) set out to develop a spatial dataset that represents these transactions. Geo-referenced plat images containing property parcel transaction data are utilized as the primary source from which the data is captured and extracted into a linear referencing system (LRS). The HTML5, web-based Raster-to-Centerline Event Collector application (RCEC) is a user-friendly solution alternative to an out-of-the-box Event Editor. The tool integrates GIS and LRS technology with traditional survey data, allowing MDOT SHA to easily find, identify and report existing land ownership changes using an intuitive route-based approach. By facilitating the identification and sale of “extra lands” that the State of Maryland otherwise would not have known to be in its possession, this tool better prepares MDOT SHA to engage with customers in an efficient and informed manner. This presentation will focus on the technical design, operation and use of the MDOT SHA Raster-to-Centerline Event Collector application as well as outlining the anticipated benefits of better managing one of Maryland’s most valuable assets: land.”

“Colorado DOT (CDOT) recently completed a LiDAR pilot project with Bohannan Huston, Inc. (BHI) and Transcend Spatial Solutions (Transcend). For this pilot, approximately 25 miles of highly-accurate LiDAR data was collected along a I-70 near Denver. The processed LiDAR point clouds and imagery were then used by BHI to extract roadway features such as edges of pavement, line striping, shoulders, signs, and guardrails. The extracted features were then made available for visualization through Transcend’s Road Analyzer straight line diagramming product. Road Analyzer was implemented as a part of the Geospatial Roadway Data Management System (GRDMS) project and had already been configured with CDOT’s HPMS data. The imagery and point clouds collected were also configured to work with Road Analyzer resulting in a comprehensive integrated visualization solution. “

Enterprise Data Enhancement for Planning through Geospatial Enabled Linear Referencing
Congressional A & B
“In 2012, when Congress enacted MAP-21, FHWA initiated the All Road Network of Linear Referenced Data (ARNOLD), a National Linear Referencing System (LRS) highway system. This legislation required the State DOT’s to build out their LRS’s to include all public roads. Since that time and the subsequent passage of the FAST Act, the importance of ARNOLD has increased since it is the foundation for several of FHWA’s performance measures that are tied to it. Also, it is a required component of many FHWA Enterprise systems including HPMS, FMIS, NBI, Safety and Planning to name a few.However, most of the RTAs ( Regional Transportation Authority including Metropolitan Planning Organizations (MPOs), Rural Planning Organizations (RPOs), Regional Planning Commissions (RPCs), and Councils of Government (COGs)have faced challenges using LRS-based GIS and may not even be aware of the National ARNOLD effort. In the case of traffic demand modeling and simulation, MPOs require the transport network to have an accurate topological connectivity that comprise of links and nodes. While LRS is a great way to integrate data for linear events, it is often difficult to integrate or transfer the data from a given Linear Referencing Method (LRM) to a topologically connected traffic model network. The FHWA LRS guideline for ARNOLD did not address how data integration can be achieved from the ARNOLD LRS to an MPO model network which must follow the principal of link-node connectivity. Therefore, addressing this issue regarding data integration is a prime requisite to gain maximum benefit from the ARNOLD. This project summarizes the recent FHWA initiative to development a detailed methodology which would guide the Nations MPOs so that they can fully leverage a Linear Reference System within the ARNOLD design principal to enhance transportation modeling and geospatial development.To date this project has interviewed several of the Nations MPO’s to measure the state of their geospatial and modeling practice in regards to LRS. The research is ongoing and the ultimate outcome of this project will be to develop guidance that includes recommending systematic processes to expand LRS uses among MPOs for planning and travel demand modeling applications. This presentation will present the finding of the project and the guidance that is being developed.”

External Business System Integration with Roads & Highways
Augusta A & B
Many DOTs have multiple business systems through various vendors. These systems are all great standing on their own managing the data within them. Some even incorporate GIS. However, when looking at an Enterprise GIS, all systems need to communicate with the others. Also most DOT data is road related so visualization requires use of the authoritative road data.At LADOTD, we have several systems that are used. Listed below are a few of the vendor related applications that we either have or plan to integrate with the Roads & Highways implementation:Traffic Count DataMS2Pavement Condition DataDeightonOperations Inventory & Work OrdersAgile AssetsProject Systems DataSAPMS2 and Agile Assets will use a similar integration pattern using ESRIs REST API and LaDOTDs LRS Service to populate Route and Measures in their respective databases. Each will use the geometryToMeasure to generate a json of the RouteID and Measure values, the parse the data to populate in the respective tables for each business system. The external events can then be displayed in a web service to place on a map.Deighton’s dTIMS integration pattern is quite different as historic and current PMS data will be migrated into R&H as events and then managed by R&H. New collections will be appended to these events where feature services can be published for map display. dTIMS will then consume the event data for analysis and reporting.Integration between SAP and ESRI is much more complex. SAP is used Statewide as an Enterprise Resource Program (ERP) and houses sensitive information. ESRIs preferred integration pattern would be to upgrade SAP to Hanna, and use an ESRI add on to integrate the two systems. This still leaves some configuration issues, as SAP resides on a separate domain network and has its own firewall.

Arizona Department of Transportation’s Roadway Characteristics Inventory has historically been a point and linear set of data. In recent years the need for the addition of a LRS enabled polygon has become ever present to support internal customers such as pavement and bridge inventory teams. Another data needs is the use of off network elements. This is especially important for asset inventory items where the location of an event such as a sign should stay at its physical location but still be associated with a route and measure. These are two elements currently not supported within the esri Roads and Highways tool. This presentation will discuss the business needs and a facilitated discussion on possible solutions and best practices.

A GIS-T Approach to Horizontal Curve Data Collection and Assessment
Royal Dublin A & B
“AbstractThis work describes the application of GIS-T methodology to horizontal curve data collection and assessment with practical examples of projects completed in 2017 for Ohio DOT and WSDOT. The projects were designed to meet a December 31, 2019 FHWA mandate for horizontal alignment curve signage, on all public roads with greater than 1,000 AADT, per the 2009 MUTCD. The presentation will describe positive results from the examples to demonstrate how GIS-T can be used to facilitate efficient outcomes for large-scale horizontal curve assessment projects. For each project, framework LRS and roadway element data from the transportation agencies were combined in a GIS-T database. This information was used in operations for vehicle route planning and scheduling, and then GPS, digital ball-bank indicator (BBI), and sign inventory data were subsequently collected in the field and imported into the GIS-T database. The results of the data processing were then converted to horizontal curve assessments based on curve geometry, superelevation, and advisory speed statistics obtained through a highly automated system. Geospatial and statistical analysis were utilized to provide comprehensive, efficient project tracking and quality control. Throughout the process, web maps provided visualizations for operations support and to enable stakeholder verifiability. The presentation will include examples from the web maps.”

The Applicability of Zipper Merge Versus Early Merge in Kentucky Work Zones
Royal Dublin A & B
“In an effort to improve work zone safety and streamline traffic flows, a number of state transportation agencies (STAs) have experimented with the zipper merge. The zipper merge differs from a conventional, or early, merge in that vehicles do not merge into the lane that remains open immediately after being notified of a lane closure. Rather, vehicles continue to occupy all lanes until they reach the taper, at which point vehicles take turns merging into the open lane, creating a zipper pattern. At the request of the Kentucky Transportation Cabinet (KYTC), Kentucky Transportation Center (KTC) researchers reviewed the performance of the zipper merge as documented in case studies from other states and analyzed two instances of the zipper merge being implemented in Kentucky. The case studies used a blend of quantitative and qualitative, observational data. At one test site, GIS mapping techniques were used to visualize the data and draw conclusions. Here, the zipper merge brought about minor, although statistically insignificant, improvements in traffic flow and roadway safety. The second site analysis relied more heavily on qualitative data. The zipper merge appeared to improve traffic flow, reduce backups, and minimize the area impacted by construction. While neither case study offers definitive evidence that the zipper merge is significantly more effective than the early merge, they offer limited support for its use. On this basis, researchers suggest its continued implementation on other KYTC projects. Implementing the zipper merge elsewhere in Kentucky will enable further data collection and potentially identify locations and situations for which the zipper merge is the most appropriate merging method. “

Utilizing Paratransit AVL Data as a Source for Traffic Analysis
Royal Dublin A & B
“In Miami-Dade County, the Paratransit mixed vehicle fleet exceeds 15 million miles per year. Paratransit systems produce significant AVL records, which include LAT/LON, speed, and direction of travel. This AVL ‘big data’, to the tune of up to 250 thousand records per day, can be utilized as a source of speed per time of day of road segments. Data will be analyzed and compared to published historical speeds for roadways within Miami Dade County to determine the accuracy of the Paratransit averages relative to traffic monitoring sites compiled data. “

Leveraging a Rules Based Approach to Solving Transportation Data Management Issues
Congressional A & B
The Federal Highway Administration, Arizona DOT and Kansas DOT (among others) have implemented a Rules Based Approach to managing their transportation networks and assets. A rules-based approach ensures that processes are easily automated and repeatable, across the enterprise and across different technology platforms. By turning Subject Matter Expertise into user-managed rules, these Transportation Agencies ensure that the best judgements are applied objectively and consistently. Automating complex, time-consuming and previously manual processes dramatically reduces the time and cost of essential tasks such as data integration, data validation, data cleansing and data enrichment. This presentation will focus on how these three transportation agencies are using a Rules Based Approach to solving their data management needs including:
  1. Federal Highway Administration building a topologically based ruleset to help improve the performance and the accuracy of HPMS submissions.
  2. Arizona DOT developing rules to validate county submissions and determine what constitutes a change in the road network (Change Detection).
  3. Kansas DOT developing rules to identify LRS network anomalies from a NextGen991 to LRS conflation effort.The presentation will also highlight how other Transportation agencies can leverage these workflows and rules-based approach within their organizations to help with their Data Management.”

Creation of a Roadway History System using ArcGIS
Royal Melbourne A & B
The GIS Team within the Florida Department of Transportation’s District One Office coordinated a massive campaign to bring documents from as far back as the 40’s into a modern-day GIS System. Collecting roadway information from plan sheets, the team created a GIS layer to reference historical documents for projects such as: abandonments, transfers, reconstructions, redesigns, widenings, realignments, and resurfacings. One of the key uses of this system is to document and inform users of what was added or deleted from the roadway system over time. This is one of our may apps built to focus on district business needs and is designed using the FDOT GIS Resources that are shareable across our Department’s GIS Platform. The amount of time and money saved in the long run is quite remarkable.

Next Generation Data Discovery: fusing structured and unstructured content from multi repositories
Royal Melbourne A & B
The Utah Department of Transportation (UDOT) implemented a powerful, geospatially enabled search solution for managing structured and non-structured content including both spatial and non-spatial file formats. UDOT’s “best of both world’s” solution indexes files and associated metadata records in repositories where they reside along with data available via web services, without moving or duplicating data. The easy and intuitive user interface enables users at all experience levels to quickly find relevant data from multiple locations simultaneously. Users increase their efficiently since they no longer need to know where data resides or how to search and discover all of the available data stores. One of the challenges UDOT faced was comprehending the content, location, and quality of the myriad data sources that exist within the different divisions of the organization. Turning data into usable, powerful information is an on-going challenge that directly improves the way UDOT does business. The solution based on PTFS’ Knowvation Content Services Platform (CSP) also creates searchable, intuitive, easy-to-use results that allow the user to understand what information is available to them without navigating many repositories, or moving/duplicating data. The solution is built on an extensible framework which allows for continuously adding new formats that can be indexed and displayed by the program, providing a flexible and nimble tool. Finally, an easy and intuitive search interface allows users to utilize geospatial, full text, and metadata searches in any combination to find the most relevant files. The solution also provides a powerful faceted search functionality based on the structure of the content, such as hierarchies, data ranges, or time spans. The initiative demonstrated the ability of the software to create a master index from many data repositories, support sophisticated search and discovery techniques, and improve multi-disciplinary, complex decision-making processes. Software usage across the UDOT enterprise and by its partners will ultimately allow for a comprehensive understanding of UDOT’s data landscape, regardless of differences in storage methodologies, naming conventions, or management techniques that exist between different Divisions or Regions. A widget built for Esri ArcGIS enables users to access the full functionality from the ArcGIS interface.

Creating Travel-Time Contour maps using NPMRDS
Royal Dublin A & B
“The travel time data from the National Performance Management Research Dataset (NPMRDS) has been made available by FHWA to all metropolitan planning organizations since 2013. The detailed dataset that contains the travel times at every five minutes intervals has proven to be very useful to identify congestion on all roads that are part of the National Highway System (NHS). Several GIS interfaces exist now that display a large variety of congestion charts and graphs of speeds based on the NPMRDS. However, none of the existing interfaces have used this dataset to create travel time contour maps.Travel time contours are a very useful tool to measure the attractiveness of major trip generators, such as airports, shopping malls or schools. In the past, the North Central Texas Council of Governments (NCTCOG) has accomplished these analyses using the travel times forecasted using the Travel Demand Model. Until recently, NCTCOG started to use the NPMRDS for this task.The approach followed is based on a travel model roadway network that is populated with NPMRDS speeds on those links that are part of the NHS, which corresponds to all freeway segments and major arterials. For the remaining links, the travel model estimated speeds are still used. This process requires a conflation process to transfer the data from the NPMRDS network to the travel model network. The roadway network with speeds assigned to all links is then used to create travel time contours through the utilization of a tool available in TransCAD.The presentation will show, among others, the following applications: number of jobs or households available for specified time intervals from or to a given location, comparison of accessibility between two CBDs, Dallas or Fort Worth, population served by the regional airports, accesses to major events of sport venues. “

Spatial Data Management Considerations for Crash Mapping and Analysis in Wisconsin
Royal Dublin A & B
“The Wisconsin Department of Transportation (WisDOT), working in partnership with the Traffic Operations and Safety (TOPS) Laboratory at the University of Wisconsin-Madison, has undertaken a modernization effort to improve its crash mapping and analysis capabilities for safety engineering and program planning purposes. At the outset of the project, a preliminary business needs assessment was conducted to identify current and future uses cases for crash data and analysis capabilities within the Department. The purpose of this assessment was to help define the underlying technical requirements that will drive both near term and longer term crash mapping and analysis tools development. This presentation will focus on the key GIS / LRS considerations for spatial data management when implementing a crash mapping and analysis system that were identified during the assessment process. In particular, WisDOT currently manages several different sources of crash location information including “real-world” coordinates and two different linear referenced network locations. All three representations serve important needs within the Department. This presentation will discuss why those differences exists and how the future crash mapping and analysis system implementation will attempt to accommodate the different, sometimes conflicting, requirements for crash location information.”

Network Screening for Safety on State-Maintained Roads in Kentucky
Augusta A & B
“This is an ongoing study, which is not yet completed, but will be completed before the GIS-T Symposium. The Kentucky Transportation Cabinet (KYTC) utilizes the Strategic Highway Investment Formula for Tomorrow (SHIFT) to rank transportation projects in the state using the following criteria: improving safety, preserving existing infrastructure, reducing congestion, fueling economic growth, and spending tax dollars wisely. Projects receive a score for each component of SHIFT, and the component scores are combined into an overall SHIFT score, which is used to determine the best projects for the state.As a part of the safety component of SHIFT, researchers at the Kentucky Transportation Center (KTC) used Highway Safety Manual (HSM) guidelines to develop state-specific safety performance functions (SPFs) for all roadway types to model crashes on Kentucky’s state-maintained roadway network. To facilitate the creation and application of these SPFs, researchers created roadway segments that were homogeneous with respect to roadway characteristics such as functional class, traffic volume, number of lanes, lane width, shoulder width, median width, curvature, and grade. The Overlay Route Events tool in ArcMap was used to convert the various shapefiles with this roadway data into a single shapefile of roadway segments with homogeneous characteristics. Once homogenous segments were created SPFs were used to predict crashes on each segment. The SPF crash predictions were combined with historic crash data using the empirical Bayes (EB) method to calculate an adjusted estimate of crashes that accounts for regression to the mean. The difference between the EB crash estimate and the SPF crash prediction is called excess expected crashes (EEC), which is the metric that SHIFT uses to score the safety component of all transportation projects.The EEC calculated for every homogeneous, state-maintained roadway segment was plotted in ArcMap, and the symbology was adjusted so locations with higher EECs stood out in thick red lines. This map of the EECs for state’s roadway network was distributed to each highway district and metropolitan planning organization to use to identify locations for safety-based transportation projects. “

Roadway Cross-section Data for MIRE and More
Augusta A & B
“When strategizing on how to inventory the 200+ Model Inventory of Roadway Elements (MIRE) data elements, staff at Washington, DC’s Department of Transportation (DDOT) were not overly optimistic. Many of the elements were difficult to collect and had to be continually collected every so often to ensure the information was accurate. When scoping out the level of effort for such an undertaking, many around the room stated that it was too expensive or time-consuming to be worth it.One of staff noticed that many of the reference figures depict a cross-section of the roadway to describe how the data needed to be collected and stated, “”Why don’t we just collect that?”” We laughed at first, but the more we thought about it, the more it made sense. Collect and maintain a cross-section of the roadway and extract out (hopefully) everything related or relevant to the cross-section. With that, the project to collect every lane, buffer, barrier and median as an LRS feature was born. This project data collection was officially completed in late September, 2018 and we’ve finally had a chance to see what we can do with a LRS cross-section representation of the roadway. This presentation highlights the basics of our Python-based cross-section LRS processing to extract MIRE data elements. Additionally, we will update on the progress of using these same data to extract a routable GIS network.NOTE: This is a follow-up on DDOT’s MIRE data collection presentation from 2018.”

Integrating Geo-situational Awareness with MS Dynamics for Customer Service
Augusta A & B
When the third largest DOT was ready to modernize the heart of its Customer Service Center application, it chose to combine the stability of Microsoft Dynamics with the powerful geospatial capabilities of the Esri platform to create a system that provides seamless workflows and situational awareness for Virginia’s customer service agents. Virginia’s Customer Service Center application (CSC 2.0) allows customer service agents to receive and process multi-channel requests (phone, web, social media) for a multitude of concerns such as damage to assets, road conditions, or hazards that may affect travelers. Agent workflows are driven through geospatial automation that ensure speed and accuracy of data entry and are visually enhanced with a powerful ArcGIS JavaScript map interface that seamlessly integrates within the MS Dynamics system.Key requirements of VDOT’s customer service center system are near 100% uptime, a high level of resiliency, and ease of maintenance. The CSC 2.0 architecture achieves this by remaining 100% configured within MS Dynamics and loosely coupling the map with bidirectional requests. The CSC 2.0 map incorporates a rich collection of VDOT business data and services from other sources – all of which is visible to the agent and can be queried in the background to provide enhanced information for inclusion in the service request. As a credit to VDOT, 3+ years after entering statewide production use, the system has helped VDOT successfully manage multiple major statewide weather events. In addition, the same load balanced ArcGIS Server stack is now being used to deploy a brand new asset management system. Much like CSC 2.0, this new VUEWorks system has been configured from the ground up to leverage VDOT’s Enterprise GIS system to save time and reduce errors and duplication of effort.

Lessons Learned Maintaining Multiple LRM’s
Congressional A & B
“Many DOTs reference their data using multiple linear referencing methods, or LRMs. Esri Roads and Highways (R&H) supports multiple LRS Networks in a single ALRS. Each LRS Network acts as an independent route layer but uses the same centerlines across all networks. This should make it easy to translate from one LRM to another. R&H does not provide support for maintaining these networks together. Edits performed on one network must be repeated across all other networks. This duplicate effort is cumbersome, time consuming, and inefficient. Often LA DOTD has found that the multiple LRM Networks become out of sync. This presentation will cover the approaches tested and lessons learned in working out the details to provide system described below.At LA DOTD, we have two LRM’s. The primary LRM (StatewideRoutes) is based on state highways and public road names. The secondary LRM (LRSID_Routes) is based on Control Section which is the Department’s historic means of tracking inventory, projects, and finances. We have developed and improved a way to maintain the two LRM’s with one set of centerlines. We maintain the control section based LRSID Network as a Registered Event in R&H (LRSID_Event) and then only edit our StatewideRoutes LRS Network, which is used for maintaining attribute data including road inventory, traffic count, pavement management, and bridge data. The ultimate goal is to submit the HPMS Report using this data. The approach is to maintain the primary LRM. The LRSID_Event location and measure information are controlled via R&H event behavior when the StatewideRoutes LRM is edited. The LRSID_Events are then used to create and maintain the LRSID_Routes LRM. With these in place, all data managed and located on the primary LRM can be identified by Report using the secondary LRM and distributed throughout the Department as done historically.”

Maryland’s Road Closure Reporter
Royal Melbourne A & B
“Maryland is one of the Country’s smallest states, however has one of the densest populations. With the ocean and bay on the east and mountains in the west, the State faces significant natural hazards, such as floods, hurricanes, storm surge, and snow storms. The State’s emergency response to incidents, cascades multiple jurisdictions, authorities, and stakeholders. In the past, no one authority was able to capture a comprehensive view of road closures across the State. Hurricane Sandy demonstrated that while local authorities did an excellent job of capturing road closures in their area, a comprehensive view of the operating theater was missing. To address the need, the Maryland Department of Transportation (MDOT) State Highway Administration (SHA) developed a State wide road closure application “Maryland’s Road Closure Reporter (MDRC)” utilizing Geocortex. MDRC is a free tool for local jurisdictions to easily and authoritatively submit, manage, disseminate, track and archive both planned and event based road closures for their jurisdiction as they deem necessary. MDRC was constructed by MDOT/SHA working with local jurisdictions and in partnership with the Maryland Department of Information Technology (DoIT). During this session, attendees will receive an overview and live demo of the MDRC application.”

Measuring the Effect of Weather Events on Long-Haul Truck Traffic Using Anonymous Truck GPS Data
Royal Melbourne A & B
Severe weather can have major effects on traffic volumes. Unlike drivers of passenger vehicles who may choose not to travel during inclement weather, freight truck drivers adhere to delivery schedules requiring them to alter routes rather than cancel a trip. A better understanding of the effects of weather events on truck traffic can assist state and regional transportation agencies in developing freight-oriented programs and policies for road and winter maintenance, structural and geometric pavement design, highway life cycle analysis, and project prioritization. Few studies have been able to model the effects of weather on truck traffic separately from that of total traffic due in part to limited availability of truck data. With the increasing availability of truck GPS data, we can now develop more robust models to explain the temporal and spatial impacts of weather events. In this study, we use anonymous truck GPS data to enhance spatial regression models to predict Vehicle Miles Travelled (VMT) and Vehicles Hours Travelled (VHT) changes of trucks resulting from weather events. This study develops a predictive spatial regression model for long-haul truck movements. The spatial regression model captures the effect of weather at one location on truck movements at that location and at neighboring locations, in effect showing the re-routing behavior of trucks. The estimated model measures weather impacts including extreme hot/cold temperatures, winter storms, wind gusts, fog, and snowfall. Moreover, instead of using static truck traffic counts, i.e. from Weigh-in-Motion (WIM) stations, for model estimation, this study uses truck GPS data. GPS data provides complete truck paths including origins and destinations, stop locations, and routes allowing for estimation of VMT and VHT. This study presents (i) GIS-based methods for fusing truck GPS and weather data, (ii) model estimation techniques, and (iii) key findings. Findings are based on application of the methodology to the State of Arkansas using national truck GPS data for the years 2016 and 2017 and weather data from Modern-Era Retrospective analysis for Research and Applications (MERRA), Version-2 through the LTPP InfoPave Climate Tool. While existing studies have used GPS data to look at historical changes in travel patterns due to weather events, the model-based approach in this work extends applications geared at prediction of weather impacts such as increased flood and storm frequency and severity.

Consulting with professionals who have experience with this process is like having a guide take you down a canyon rim trail – it’s clear where you want to end up (top of the rim to bottom of canyon), but successfully navigating the middle isn’t necessarily so obvious. MRCOG recognized the benefits of a journey partner and sought an experienced consultant, Timmons Group, to advance their knowledge and use of the system. Together, we developed a plan to realize the goal of a full R&H implementation, built on an understanding of MRCOG’s data, staff capacity and technical know-how, and business needs. This plan includes three (3) on-site workshops, with remotely conducted activities in between, designed to guide MRCOG through implementation. Like all plans, the key is flexibility. In our first workshop, we realized that our plan needed adjustment; staff changes have occurred at MRCOG and, fortuitously, data exchange planning with the New Mexico DOT has advanced, changing our assumptions and recommendations for data sources and modeling, and data management flows between MRCOG and the DOT. During that workshop, we also developed a great level of collaboration and trust that we believe will be instrumental in the success of our dynamic plan for implementing R&H through leveraging data from the DOT while fostering a strong culture of data quality and collaboration. Sharing our experience to date could benefit those thinking about the same journey through a discussion of:1. A brief outline of our initial plan to implement R&H together2. Why collaborative trust is essential between consultants and client governments3. Updates on our progress and lessons learned to date “

Analysis of Colorado Truck Parking Demand with ATRI Freight GPS
Royal Dublin A & B
Finding safe, legal truck parking has historically been a major issue for truck drivers, but the problem is growing quickly as traffic congestion increases, public rest stops are closed due to budget constraints and private truck stops are pushed farther out of the metro areas as growth trends change planning and zoning priorities. Changes to federal Hours-of-Service regulations and Electronic Logging Device mandates have changed where and when truck drivers must park. Most noticeable is that e-commerce and other changing consumer spending trends are changing supply chains and freight distribution networks, both of which change where and when a truck driver needs to park. The ability to move freight safely and efficiently via truck through and beyond Colorado depends on the provision of adequate truck parking throughout the state freight network. The many benefits of safe truck parking include enhanced safety for both the traveling public and truckers, improved local and regional economic outcomes, and improved public perception of truck movement along highways and Interstates. As is reflected in many states, the current parking system in Colorado faces challenges in the form of unpredictable and increased staging and detention times, Hours of Service regulations, fluctuating weather conditions, and increases in freight and other traffic on the roads. Unique challenges exist in evaluating freight movements, most notably the question of how to evaluate freight-specific movements separately from all other traffic. While truck counts are available from ITS systems installed on highways throughout Colorado, evaluating truck parking facilities for both public and private institutions can be difficult due to the lack of available data and costly field data capture for what amounts to over 150 facilities. An inventory of available truck parking and related amenities was performed in order to determine a baseline of truck parking supply across the State of Colorado. A survey of truck drivers and operators was also performed to gauge the magnitude of perceived truck parking supply. FHU worked with the American Transportation Research Institute (ATRI), one of the country’s leading experts in truck parking issues, and used ATRI’s freight vehicle GPS data for the analysis of parking demand and needs. This presentation will review the methods, assumptions, and results of the study through the use of both static and web maps.

Leveraging in-service performance evaluation tied to mobile data collection
Augusta A & B
“Iowa DOT (IADOT) has been doing inventory and inspection/condition mobile data collection for six years for a variety of features within the primary road right of way. Through a new initiative we are working to tie in-service performance to mobile data collection as a response to crashes in the ROW. This project, as well as other tools, will allow for planning in design, viewing of inventory/condition information, supporting decision making for field, district and central DOT management teams. This presentation will talk about processes/tools we are leveraging to make information available.”

Estimating Safety Benefits of Connected and Autonomous Vehicles – SR 70 Pilot Study
Augusta A & B
The goal of this project is to develop quantifiable and scientifically defensible estimates of the potential safety benefits that could be expected from the adoption of CAVs in Florida. More specifically, this project will estimate the potential reduction in crashes along State Road (SR) 70 (between I-75 and I-95) by examining historical and predicted crash data and evaluating how particular CAV technologies could prevent or mitigate certain types of crash events.

Improving Crash Collection & Quality at MassDOT
Augusta A & B
“The Massachusetts Department of Transportation (MassDOT) is tasked with collecting crash data, providing timely and accurate vehicular crash information to a number of Federal, State and Local authorities to support decision making, as well as ensuring the information is also available publicly. MassDOT has had an existing “geo-coder” system in place since 2004 which assisted in pinpointing the geographic location of the crash and also had several legacy processes and applications in place that support the analysis and reporting on the data. In 2017 MassDOT began development of a comprehensive replacement and enhancement to this system. Some of the goals of this project included:•Replacing and enhance the existing crash geocoder/validator system, leveraging Esri’s Roads and Highways platform•Developing web services to validate and geo-locate crash data real time•Developing a new Crash Database that will:ointerface with the new geocoder/validator system to maintain geo-location and other data attributesobe used as the source for crash reporting and in-depth crash data analysisosupport a new, public-facing crash data portal.•Developing synchronization utilities to ensure real-time synchronization with the crash data stored in the RMV Crash Database•Provide Reporting & Analytics Tools to allow users to use the crash data in an efficient and user-friendly mannerThis presentation will provide the attendees with an overview of the history that lead up to the project, the challenges that were faced, the goals the project had, and the design for the system that is being built and how it will improve on the accuracy, quality and timeliness of the data that is created and used for analysis in the system.”
