TPICS, TIGER and United States experience: A focus on case-based ex-post economic impact assessment

This chapter presents the results of research recently conducted by the authors on ex-post analysis focused on the long-term economic impacts of transportation system investments in the United States. For a variety of reasons, the United States has had a tradition of making transport investments to address economic development goals and applying ex-post analysis to assess achievement of economic development impacts. These past studies are reviewed, as are some of the deficiencies and suggested improvements in methods for ex-post analysis.
