Assistance to Contractors to Archive Their Data for Reliability and Related Projects

To address the challenges of moving people and goods efficiently and safely on the nation's highways, Congress has created the second Strategic Highway Research Program (SHRP 2). SHRP 2 is a targeted, short-term research program carried out through competitively awarded contracts to qualified researchers in the academic, private, and public sectors. SHRP 2 addresses four strategic focus areas: the role of human behavior in highway safety (Safety); rapid highway renewal (Renewal); improved travel time reliability through congestion reduction (Reliability); and transportation planning that better integrates community, economic, and environmental considerations into new highway capacity (Capacity). Under current legislative provisions, SHRP 2 will receive approximately $150 million with total program duration of 7 years. Additional information about SHRP 2 can be found on the program's Web site at Focus Area Background Seven major factors account for approximately half of all traffic delay, and therefore, a great deal of the uncertainty associated with travel time: (1) traffic incidents, (2) weather, (3) work zones, (4) fluctuations in demand, (5) special events, (6) traffic control devices, and (7) inadequate base capacity. These factors often interact, which increases the challenge of reducing the uncertainty of travel time that drivers experience. The overall goal of the SHRP 2 Reliability program is to reduce non-recurrent congestion through incident reduction, management, response, and mitigation of the contributing root causes. Achieving this goal would significantly improve travel time reliability for many types of person and freight trips on the nation's highways. Travel time reliability refers to how travel time varies over time and the impacts of this variance on highway users. In other words, for repeated travel or vehicles traveling the same route, there is an underlying distribution of travel time for a particular trip between two points within a specific time period. Individual travelers respond differently to the factors and uncertainties associated with the travel time. So do those involved in freight transportation. For important trips, such as a trip to the doctor or a just-in-time freight delivery, drivers will build extra time into the trip to ensure a high probability of arrival within a time window. SHRP 2 Contractors performing reliability or related work in the Reliability and other areas (e.g. Capacity) do not have provisions in their contract requiring them to prepare the various types of data they use or produce for inclusion in the archive likely to be developed under Project 13a. Many of the contractors are likely to need a small amount of supplemental financial resources (to be determined on a case-by-case basis) in order to archive their project data. In addition resources would be provided for technical assistance. Reliability project data can take a wide variety of forms including metadata, alpha-numeric data, video, reports, web pages, and software.
