The NCHRP 17-87 method is well suited for quantifying changes in pedestrian delay and satisfaction at specific uncontrolled crossings.

Pedestrian Quality of Service Analysis 81 Walkability Measures Walkability measures evaluate a street's pedestrian QOS from a broad perspective, with the expectation that improving a street's walkability will increase pedestrian activity. ese measures typically incorporate a variety of qualitative and quantitative factors that evaluate a facility or neighborhood's attractiveness for making walking trips, including the availability, quality, and safety of pedestrian facilities; adjacent land uses, aesthetics, and personal security concerns; and access to key destinations, among others.
