Research Summary:

Accessibility is a critical metric for measuring land use and a transportation system's performance, which has been studied for decades. However, the availability of several definitions of access as well as technical barriers and data limitations have presented challenges for monitoring its progress and understanding its impact on social equity.  In this project, the Contractor will identify key accessibility metrics, develop an appropriate method for quantifying accessibility metrics, build a tool to analyze and discuss the variation in the final output of the metrics, and identify best practices for monitoring and tracking implementation of Sustainable Communities Strategies (SCSs) progress as required by SB 150 (Allen, Chapter 646, Statutes of 2017).
