Capacity Implementation Support

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). Administered by the Transportation Research Board (TRB), 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); congestion reduction through improved travel time reliability (Reliability); and transportation planning that better integrates community, economic, and environmental considerations into new highway capacity (Capacity). Under current legislative provisions, SHRP 2 has expanded its efforts to include activities such as office and field pilot tests and product validations that help to prepare research results for implementation. Additional information about the program is available on the website: The charge from Congress for the SHRP 2 Capacity program was to develop approaches for systematically integrating environmental, economic, and community requirements into the analysis, planning, and design of new highway capacity. The scope of the SHRP 2 Capacity program extends from the early stages of the transportation planning process, when many potential alternatives are being considered, through project development. When decisions include a major highway component, further development of the highway option is within the scope of the program. When decisions are made that lead to non-highway options, further development of the non-highway component is outside the scope. Research conducted in the SHRP 2 Capacity program focused on six major theme areas: collaborative decision making; economic impact analysis; integration of highway planning, conservation planning, and environmental review; advanced modeling and networks; operations to improve highway capacity and reliability; and freight planning. Multiple research projects were funded under each of these theme areas. Follow on development contracts have funded activities to convert research results into products that can be directly used by implementing agencies. Other development contracts have funded pilot testing of the products developed in the research phase. A list of all the projects funded under the Capacity focus area can be found on the SHRP 2 website at The overall objective of the Capacity focus area is to systematize collaborative decision making to achieve better, faster project decisions that are sustainable. The results of a number of the research products have been incorporated into a web portal called TCAPP (Transportation for Communities -- Advancing Projects through Partnerships). Tools have also been developed for individual products that will be available for use by implementing agencies. An overall implementation plan for Capacity products will be developed jointly by the Federal Highway Administration (FHWA), the American Association of State Highway and Transportation Officials (AASHTO) and TRB over the next several months.
