Title: Varying Influences of the Built Environment on Household Travel in Nine Diverse Regions of the United States
Abstract: This study pools household travel and built environment data from nine diverse U.S. regions to produce travel models with more external validity than any to date. It uses a large number of consistently defined built environmental variables to predict five household travel outcomes—auto trips, walk trips, bike trips, transit trips, and vehicle miles traveled (VMT). It employs multi-level modeling to account for the dependence of households in the same region on shared regional characteristics. It estimates “hurdle” models to account for the excess number of zero values in the distributions of dependent variables such as household transit trips. It tests built environment variables for three different buffer widths around household locations to see which scale best explains travel behavior. The resulting models are appropriate for post processing outputs of conventional travel demand models, and for sketch planning applications in traffic impact analysis, climate action planning, and health impact assessment.
