An Examination of 14 Projects to Validate the Results of SHRP 2's Transportation Project Impact Case Studies (T-PICS)

This report provides an evaluation of the Strategic Highway Research Program 2 (SHRP 2) product known as Transportation Project Impact Case Studies (T-PICS). T-PICS was created to offer a preliminary planning tool for planners, policy makers, and others interested in gauging the economic impact prospects of typical highway capacity improvement projects conceived across a wide array of contexts, including project type, geography, project motivation and project length. The T-PICS tool consists of a simple user interface that accesses a database of 100 completed transportation projects, representing a variety of project types, sizes, and broad geographical distribution. To validate the results of T-PICS, the economic impact estimates generated by T-PICS were compared with the observed and modeled economic impacts of 14 independent projects representing a variety of project types around the country. Each project has been completed and operational for a minimum of five years to ensure that the test case study projects have had time for resulting economic impacts to occur. Detailed results and recommendations that address the general functionality and usability of T-PICS are provided.
