Major emphasis of this conference was the identification of models and methodologies for organizing and using existing data for designing future data collection efforts and for applying systematic analysis and scientific procedures to the understanding of policy problems and the making of public decisions regarding transportation system improvements and economic development. This overview of methodology covers the following: user benefit analysis; current approaches to impact evaluation; theories of urban and regional growth; measurement of the effects of transportation changes; modeling impacts of transportation investments; economic base analysis; input-output (i-o)analysis; regional economic models; and system dynamics modeling. It concludes with a summary of economic impact modeling.
