The evaluation of transportation projects has traditionally been carried out in the context of economic efficiency, in terms of savings in travel time, vehicle operating cost, and safety. The wider and longer-term effects on economic development (i.e., job, income and business growth) are a concern of transportation planners and decision-makers but have been often overlooked due to the lack of a reliable impact estimation methodology and/or data. Information on economic development impacts is valuable for understanding the total effect of projects and therefore, for a more balanced justification of proposed transportation infrastructure investments. This study extends the traditional transportation impact framework by examining how different types of highway improvements that have been programmed for implementation in the State of Indiana can affect the states economy, and how project- and location-specific factors interact to stimulate economic development. Temporal, spatial, and project characteristics are duly considered. The end product of this research is a quantitative tool that can be used at the project development phase by INDOT staff to estimate the economic development effects of different types of highway investments and make better decisions regarding highway investment. |
