Spreadsheet Model for Induced Travel Estimation (SMITE)

This Lotus 123 spreadsheet model applies the principles of economic analysis to evaluate highway capacity expansion in an urban setting, taking into account new travel that may be induced by highway expansion over and above that which is simply diverted from other regional highways. This model is useful for 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. 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. The accompanying paper discusses the concepts underlying SMITE, and describes an application of SMITE to the evaluation of a typical freeway capacity expansion project.
