Project Status: In Progress


This project is an interdisciplinary study among two research centers at the University of Wisconsin-Madison, with research guidance and support from four state departments of transportation (DOTs). Additional agencies will be recruited for the study through further outreach efforts.

This study will advance the use of accessibility metrics, which describe the ability of people to reach jobs and opportunities by different modes of travel, in practical decision-making and, specifically, for predicting transportation outcomes like travel demand and transit use.

Our goal is to produce robust, transferable models based on accessibility metrics so that transportation agencies can evaluate the impacts of transportation investments and land use changes without relying on complex travel demand models or scenario planning tools.
