Commute Duration Dashboard Guide: Mapping Commute Travel Times to Evaluate Accessibility

Abstract: 

Transportation planning is shifting from mobility-based to accessibility-based analysis. Mobility-based planning evaluates transportation system performance based primarily on travel speed. Accessibility-based planning evaluates system performance based on time, the amount of time required to access desired services and activities such as work, school and shops. Accessibility-based planning recognizes that many factors can affect accessibility, including mobility (travel speed), proximity (the distances between destinations, and therefore development density and mix), transport system diversity (the variety of travel modes available at a time and place), transport network connectivity (the quality of connections between modes), and affordability. 

A simple but useful accessibility indicator is trip duration, the amount of time that people spend traveling to destinations. Commute duration data—the number of minutes that workers spend traveling to their jobs—is available in the United States from the U.S. Census. Our Commute Duration Mapping website presents this and related information for most U.S. communities. This guide provides an overview of this mapping system’s controls.
