Identifying and Measuring Urban Design Qualities Related to Walkability.

Background: In active living research, measures used to characterize the built environment have been mostly gross qualities such as neighborhood density and park access. This project has developed operational definitions and measurement protocols for subtler urban design qualities believed to be related to walkability.

Methods: Methods included: 1) recruiting an expert panel; 2) shooting video clips of streetscapes; 3) rating urban design qualities of streetscapes by the expert panel; 4) measuring physical features of streetscapes from the video clips; 5) testing inter-rater reliability of physical measurements and urban design quality ratings; 6) statistically analyzing relationships between physical features and urban design quality ratings, 7) selecting of qualities for operationalization, and 8) developing of operational definitions and measurement protocols for urban design qualities based on statistical relationships.
