Federal Legislation in MAP-21 raised the stakes for transportation agencies, not only by conditioning future funding on the systematic adoption of performance measures, but also by requiring that measures be mapped to target network improvements. This gives GIS professionals a critical role in development, stewardship, and analysis of transportation system performance measures.
The theme for this workshop arose from proposals in an open call from our members, so interest is clear and the theme may be carried into future sessions. Presentation times are designated below, but we expect presenters to allow time for conversation and sharing.
Simon Lewis, McMahon Associates
“Implications of MAP-21 Performance Measures for Local Agencies”
Map-21 requires that state Departments of Transportation implement Performance Measures (PMs) for various aspects of the transportation system, though specific measures will vary by state and even within states. While few PMs are now required of local agencies, the benefits of implementing PMs should be recognized regardless of whether they are required. This presentation is intended to frame and guide the local agency PM review and selection processes. Part 1 will review developments in the field to date, a best practice framework, and key resources, by functional area. Part 2 suggests a process through which local agencies may identify and adopt their own system performance measures.

“Pavement Management Step by Step”
With guidance from Rutgers CAIT, Mercer County has developed an in-house pavement management system. Staff annually conduct a windshield pavement distress survey of each route, analyze survey data with an inexpensive U.S. Army Corp of Engineers application, and the resulting condition ratings are entered into a summary spreadsheet that drives the capital paving program. This presentation describes the County’s process and decision points necessary for other local agencies to develop their own pavement management systems. The presentation and resources gathered and developed by Mercer County will be made available for download.

“Burlington County Guiderail Inventory”
Taylor Wiseman & Taylor performed field survey location and GIS inventory of existing guide rail installations for Burlington County. A customized GIS data capture application was developed to perform the guide rail inventory. Data collection teams, utilizing tablet PC’s, performed the inventory of approximately 72 discrete guide rail elements (end treatment type, presence of rub rail, roadway offset, etc.) for 1,400 locations. As data was entered in the field, the application computed clear zones, determined associated roadway and structure elements, and allowed for the capture of indexed photographs. Federal Highway Administration guide rail priorities were assigned based on published standards that were integrated into the post-processing of the data. Upon completion of all post processing and prioritization, a file geo-database was delivered to the County for integration into their existing GIS system.

“Development of a Statewide Speed Survey for Delaware”
GPS data obtained from public vehicles in Delaware was processed to develop a state-wide travel time survey. Speeds and travel times are captured for roads large and small throughout the day in a data set that includes over 100 million measures each year. The presentation includes discussion of how this information was processed and presented to evaluate performance of the transportation network over time. Results will be compared with those obtained from other sources and methods of travel time measurement, and applications of the data will be discussed.
Jason Kreyling, Michael Baker Jr.
“Overview of NJ Transit’s Public Information Display Inventory”
New Jersey Transit’s (NJT) rail service network consists of 164 commuter rail stations and 61 light rail stations. In 2012, NJT contracted with Michael Baker Jr., Inc. (Baker) for consulting services to advance the development of a Public Information Display (PID) Inventory Program. This included the collection of the spatial location and related attributes to over 2200 PIDs. Since the physical PID inventory will be a reoccurring process an ArcGIS Online solution was crafted to leverage Esri’s Collector application. This presentation will provide an overview of the project with a focus on the challenges and solutions observed using Collector.
