National Highway Data Workshop and Conference
The biennial national Highway Data Workshop and Conference series
What is HiDaC?
HiDaC is a conference series focusing on presentations and discussions of highway system inventory and extent, highway system designations, and highway system performance. The first HiDaC was held in Saratoga Springs, New York, in 2005 followed by Nashville, Tennessee, in 2007 Oakland, California, in 2009, and Buffalo, New York, in 2011.
The next HiDaC will be held in March of 2014 in Saratoga Springs, New York.
It will be held in conjunction with the New York State DOT Highway Data Workshop, a series of training and coordination sessions held annually by the NYSDOT Highway Data Services Bureau. Both events will be held at the Gideon Putnam Hotel in the Saratoga Spa State Park during the week of March 10-14. An agenda and more details will be forthcoming.
Please contact Michael Fay, Michael.Fay@dot.ny.gov if interested or want more information.
What is the Purpose of HiDaC?
The intent of HiDaC is to encourage collective discussion of the often subjective and vaguely defined concepts used to track and assess the performance of the public highway system. All States define their highway systems in accordance with Federal Highway Administration guidance and in cooperation with Metropolitan Planning Organizations and other State and local agencies. This guidance is by its nature imprecise and vague, yet funding allocations and measures of performance are based upon the interpretation of the State in question. There is a need for a collective “meeting of the minds” among practitioners to ensure equitable treatment within and between States. Cross border coordination is another issue which would benefit from collective discussion and decision making to ensure a “seamless” highway system across the Nation.
Who is the Target Audience?
HiDaC is intended as a practitioners’ conference for new and experienced mid-level analysts and highway data managers involved with the day-to-day activities associated with highway data collection, processing, and analysis from the States, Federal government, and local planning agencies throughout the country.

Welcome and Keynote
Highway Data Overview – Panel Session
What are the biggest challenges and/or the top priorities of your state's DOT for collecting and managing data and how are you pursuing these?
HPMS Reassessment, Implementing Change
HPMS since it's inception in the early 80's, has been a vital program for FHWA. Much of the data reported in the system has a direct impact on funding, planning, performance measurement, and public accessibility to a vast amount of highway related data. This session will review the basic purpose and functionality of the HPMS with a focus on the upcoming HPMS 2010+ Reassessment.
HERS-ST using HPMS Data
A detailed breakout of a major use of HPMS data, the (Highway Economic Requirements System (HERS) model, will be presented within this session.
WEDNESDAY SEPTEMBER 23, 2009
Use of the Web as a Tool to Display GIS Maps
What has been occurring in the last few years is the further use of the web as a tool to display GIS maps, for instance, the use of Google maps that allow for displaying third party maps when they are geo-referenced. One in-house example is the street view feature Google maps provides and that is linked up with our GIS maps created for the Advanced Planning Department to quickly view locations in light of ADA requirements. Meanwhile, another example is the right-of-way information displayed via map-linking on Google Earth.
The Pavement Management Program Used at the City/County Level
This presentation focuses on how MTC uses StreetSaver in the region to track jurisdictions' performance in the area of preventive maintenance / pavement preservation, and how we use performance measures in the allocation of regional funding for local street and road maintenance. The presentation will give an overview of the software and how it is used as an asset management tool in our region.
Measuring the Quality of Traffic Information
While there are numerous data collection and estimation methods in use today, there are no broadly-accepted metrics to measure the quality of traffic information. The emergence of private providers of traffic information requires that agencies be able to verify and monitor the quality of data in order to procure it. This technical session will highlight work currently underway in both academia and industry groups to bring about clear and robust metrics and methodologies that allow agencies to evaluate and benchmark data services against their needs.
Mobile Millennium: GPS Mobile Phone as Traffic Sensors
A partnership between Caltrans, UC Berkeley, NAVTEQ and Nokia—with support from the federal Safe Trip-21 initiative—the Mobile Millennium pilot project intends to establish the modalities of traffic data collection from mainstream mobile GPS devices. With speakers from the California Center for Innovative Technology (CCIT) and the Nokia Research Center, this technical session will highlight key features of what constitutes an integrated research and development (R&D) program, including findings from the February 20008 Mobile Center field experiment, the design of the Mobile Millennium pilot, and what this all means for roadway operators.

Tour of Caltrans District 4 TMC & MTC's 511.org Ops Center
This field trip will feature the real-time operations of the Caltrans District 4 Traffic Management Center (TMC) and its integration with the 511.org services provided by the Metropolitan transportation Commission (MTC), which serves as the metropolitan planning organization (MPO) for the nine-county San Francisco Bay Area. The co-location of these two separate programs is a testament to successful inter-agency cooperation that benefits the traveling public.

Northeast Regional Highway Data Workshop & Conference
September 6-8, 2005
The first biennial highway data conference was held at the Gideon Putnam Resort & Spa in Saratoga Springs, New York, from September 6 to 8, 2005. With assistance from staff of the Pennsylvania DOT, the Vermont Agency of Transportation, the FHWA NY Division office, and the FHWA Highway Performance (HPMS) Division in Washington, the New York State Department of Transportation (NYSDOT) hosted a conference which brought together State, Federal, and local officials who deal with highway inventory, highway system designations, and highway performance issues across the country. While originally proposed as targeting the Northeast region, attendees included staff from the transportation agencies of 14 different States and the FHWA Division offices in 9 different States ranging from Rhode Island to California. In addition, there were three FHWA HQ and resource center offices represented, 15 vendors, five MPOs, and one territory (Puerto Rico).
Michael Fay of the NYSDOT Highway Data Services Bureau opened the Conference on Tuesday, September 6, and was followed by welcoming remarks from Paul Wells, the NYSDOT Chief Engineer, and Robert Arnold, Division Administrator of the Federal Highway Administration, New York Division. David Winter, representing the FHWA Office of Highway Policy Information, then spoke on the national perspective with respect to highway data. Tom Kearney, FHWA-NY Division, closed the general sessions with an interactive discussion with the audience to determine who was in attendance and why and thereby elicit the nature of highway data and the highway data community.
Following the general sessions, David Winter and Ralph Volpe of the FHWA Highway Systems Performance Division gave a mini-course on the FHWA Highway Performance Monitoring System for those attendees not familiar with HPMS.
The opening day was concluded with a welcoming dinner and guest speaker Henry L. Peyrebrune, retired NYSDOT First Deputy Commissioner. Mr. Peyrebrune spoke on the HPMS reassessment performed in the late 1990's for which he was the consultant, and compared its goals and intent with that of the upcoming HPMS reassessment in which he will also play a role.
Highway System Extent, Designations, and Performance
The remainder of the Conference was basically divided into four parts: one each covering extent, designations, and performance, followed by sessions on the FHWA Highway Performance Monitoring System which attempts to bring all three together into one common reporting format.
Highway System Extent
Michael Fay of NYSDOT led the Highway System Extent discussion with a description of the type of highway inventory data collected at the Federal (represented by HPMS) and State levels. Mark Berger of the Massachusetts Highway Department followed with a description of the types of data Massachusetts collects at the local highway level and why. All four panel participants, Michael Fay, Mark Berger, Gaye Liddick of PennDOT, and Brian Domsic of CalTrans, discussed the similarities and differences between their State's operations and those described by Mr. Fay and Mr. Berger.
Rick Bennett, NYSDOT pavement management supervisor, followed with a discussion of some of the tools used for automated highway data collection, including an Automated Road Analyzer (ARAN) vehicle, photolog, and e-score (an automated tabulation device for visual data collection). Donna Wilson then discussed the Vermont Agency of Transportation (VAOT) videolog system. As a data analysis and presentation tool, Johnathan Croft of VAOT demonstrated the power of the straight-line diagram software used by Vermont.
As an illustration of the complexities of highway information, Tom Perreault of the NYSDOT Office of Legal Affairs discussed ownership and jurisdiction issues, especially with regard to State designated arterials and State Highway Law. David Woodin of the NYSDOT Traffic Engineering & Highway Safety Division, in turn, discussed the various highway designations as represented by the signing along the highways, including Interstate, US, and State touring routes as well as county routes, reference markers, and mileposts.
Highway System Designations
Tom Kearney of the FWHA-NY Division led the highway systems designation sessions beginning with a discussion of the rules, regulations, and procedures for designation of Interstate highways (such as the recent conversion of State Route 17 in New York to Interstate 86) and the National Highway System. In conjunction with this discussion, Holly Lisle, FHWA-Iowa Division, gave a brief overview of the events being planned for celebration of the 50th anniversary of the Interstate System.
A discussion of Urban Area Boundaries, and their relationship to designation of highways with urban versus rural functional classifications, was led by Ed Christopher, FHWA Resource Center, with input from Tom Kearney, FHWA-NY, and Rich Peters, a regional planning and program manager for the NYSDOT Hudson Valley Region. Mr. Peters' experience ranges from rural Columbia County whose only city is less than 8,000 people to the well-known, very urban/suburban Westchester County of 1 million residents adjacent to New York City.
Highway System Performance
Gaye Liddick of PennDOT led a discussion of the types of performance data collected as part of highway data. Joining him were Phil Bell of the NYSDOT Office of Policy & Performance to discuss how some of this data is expected to be used in system performance monitoring and Robert Arnold, FHWA-NY Division Administrator to discuss some of the FHWA efforts in this area.
Tim LaCoss, FHWA-NY, and Rick Bennett, NYSDOT, discussed some of the pavement condition and performance data, how it is collected and how it is used. Michael Fay, NYSDOT, and Bernard Byrne, VAOT, discussed some of the traffic monitoring data that is collected and how each State uses this data to estimate travel on roads which are not routinely monitored.
Mike Long, Chief of the PennDOT Roadway Management Division, gave a comprehensive overview of the PennDOT roadway management system and how it developed and evolved since its inception in the 1980's. He provided a comprehensive picture of one State's approach to inventory and pavement condition data collection and management. Continuing with the PennDOT theme, Laine Heltebridle, PennDOT, and Carolyn Carney (formerly Carolyn Renner), Southwestern Pennsylvania Commission (the Pittsburgh area MPO), discussed the cooperative State/local efforts in Pennsylvania toward collection and management.
The final highway system performance presenter was Lou Adams of the NYSDOT Office of Policy and Performance discussing Asset Management and its dependence on comprehensive and accurate highway data to use in asset performance analysis and management activities.
The Highway Performance Monitoring System
The Conference closed with two sessions on HPMS. The first was a discussion of current activities within the HPMS function by David Winter, Chief of the Highway System Performance Division of the FHWA. Mr. Winter also discussed the upcoming HPMS reassessment introduced at the welcoming dinner by Henry Peyrebrune.
The second HPMS session and final session of the Conference was a compare and contrast session of how different States, large and small, handle the processing of HPMS data. Involved in the discussion were the FHWA Division representatives from New York (Tom Kearney), Rhode Island (Ralph Rizzo), and Delaware (Paul Lang) and the State HPMS coordinator from CalTrans (Brian Domsic).
Vendor Presentations & Equipment Displays
In addition to the main agenda of the Conference, several presentations were offered by the vendors present at the Conference displaying their products and the work they've done for different State and other transportation agencies. These presentations included demonstrations of various traffic monitoring equipment, GIS-based highway data applications, and mobile and remote highway data collection techniques. In addition to the vendor exhibit tables open throughout the Conference, NYSDOT displayed some of its own traffic monitoring, photolog, and pavement management data collection equipment during the second day of the Conference.
