Planning agencies and transportation decision makers often talk about the importance of improving access to destinations, but they rarely have the tools or resources to measure accessibility and incorporate those metrics into decision making. This report guides agencies through that process. The guide outlines general concepts, data needs and availability, analysis tools, and other considerations in measuring accessibility. It describes different ways accessibility can be measured and demonstrates how the metrics can be used in several specific project evaluation examples. It also briefly describes the potential use of accessibility metrics in predicting outcomes such as travel demand and transit ridership.
