TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-C03-RR-1: Interactions Between Transportation Capacity, Economic Systems, and Land Use provides information on the development of a large database of case studies and a web-based T-PICS (Transportation Project Impact Case Studies) tool that allow for more rapid assessment of the long-term economic impacts of highway capacity projects.

SHRP 2 Report S2-C03-RR-1 and the accompanying T-PICS web-based tool are intended to serve as a resource for transportation planners and others who are interested in better understanding the long-term economic impacts of highway capacity projects. The T-PICS web-based tool provides transportation planners with a way to search for relevant case studies by type of project and setting. The case studies include details of the projects, their impacts, and factors affecting the impacts. The web tool also provides users with an option to specify the type of proposed project and see the range of likely impacts based on the studies.

SHRP 2 Capacity Project C03 also developed three additional related materials: a data dictionary, a users guide, and performance metrics.

SHRP 2 Report S2-C03-RR-1 includes an explanation of how the case studies were selected and developed, an introduction to T-PICS, and a meta-analysis of the key relationships among factors such as project type, traffic volume, project location, and nontransportation policies aimed at fostering economic development.
