A Review of the Representation of Induced Highway Travel in Current Travel and Land Use Models

Induced travel is generally defined as any increase in travel resulting from an improvement in the transportation system. Research on induced travel has emerged over the last several decades and is currently of interest as it relates to regional land use and travel demand models. Case studies based in Sacramento, CA, Chittenden, VT, and Salt Lake City, UT have assessed the ability of existing travel and land use models to represent the induced travel effects of new highway capacity. These studies have also conducted sensitivity tests to isolate the contribution with respect to the models’ representation of induced travel. Results of this review show that when travel times are fed back to a land use mode and/or the trip distribution step, then models can represent induced travel within the range documented in the empirical literature, and the effect of new highway capacity on land use and trip distribution can significantly contribute to the model’s representation of induced travel.
