Accessibility in Everyday Planning

This chapter examines different methods to support accessibility-based analysis for both land-development and transportation projects to help forge a closer link between accessibility analysis and applied decision making in planning. Accessibility metrics vary in their measurement approach, purposes, and levels of complexity. Accessibility is normally reported in the form of a score or index to describe the ease of reaching destinations from a place, which allows analysts to compare accessibility from one place to another, or track changes in accessibility over time. The chapter then considers the foundational concepts of accessibility measurement and representation. It also demonstrates empirical application at the project level. Moving accessibility-based evaluation from the regional scenario to the project level involves more than applying regional tools to individual decisions, because project-level analysis is inherently different from a regional analysis.
