Abstract:

This paper demonstrates application of the principles of economic analysis to evaluate highway capacity expansion in an urban setting, using a sketch-planning model called Spreadsheet Model for Induced Travel Estimation (SMITE). The application takes into account new travel that may be induced by highway expansion over and above that which is simply diverted from other regional highways. The paper demonstrates how the effects of induced travel can be incorporated into the evaluation process at a sketch planning level of analysis, especially in cases where four-step urban travel models are either unavailable or are unable to forecast the full induced demand effects, such as in small and medium-sized urban areas. The methodology and the SMITE spreadsheet can be used to provide useful information to assist policy makers in evaluating proposals for specific additions to highway capacity for corridor studies.
