摘要：	Strengthening the economic vitality of a region is one of the primary reasons for investing in highway capacity. Better access to markets and labor force, reduced cost of delay, less congestion, improved safety, lower pollution levels, and a better quality of life are all elements of improving economic vitality. However, the ways in which new and improved highway capacity influences economic vitality are complex and often indirect, which complicates decisions about transportation projects. Understanding what changes in productivity result from improvements in market accessibility, intermodal connectivity, scheduling, logistics, and international competitiveness helps communities and transportation agencies identify transportation options to meet their goals. Excellent economic impact assessment tools for highway capacity planning are available, but they tend to be relatively time-consuming and expensive to use. Until now, this has meant that the economic impacts of potential projects often have not been considered in the early stages of planning and programming when many possible project alternatives are being considered. With a new web-based tool, Transportation Project Impact Case Studies, or T-PICS, economic impacts can more easily be considered during community visioning for transportation or during public and stakeholder involvement for long-range system planning or corridor planning. The Capacity focus area of SHRP 2 is broadly based on the concept that systematically considering the social, environmental, and economic effects of highway projects as they are planned, programmed, and carried out will result in better projects that can be delivered faster. The T-PICS tool provides planners with a quick and easy way to match their project criteria to case studies of similar projects (including economic and land development data both before and after project completion) so the best options can be identified early. Because not every proposed project will have the s
