Identifying and Measuring Urban Design Qualities Related to Walkability

Authors: Reid Ewing, Otto Clemente, Susan Handy, et al. (2005)
Report
Synopsis: 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. RESULTS:  Operational definitions and measurement protocols were developed for five of nine urban design qualities: imageability, visual enclosure, human scale, transparency, and complexity. CONCLUSIONS:   A field survey instrument has been developed, tested in the field, and further refined for use in active living research.

 

Assessing the impact of urban form measures in nonwork trip mode choice after controlling for demographic and level-of-service effects

Report
Synopsis: The relationship between travel behavior and the local built environment continues to be a contentious issue, despite several research efforts in the area. The current paper investigates the significance and explanatory power of a variety of urban form measures on nonwork activity travel mode choice. The travel data used for analysis is the 1995 Portland Metropolitan Activity Survey conducted by Portland Metro. The database on the local built environment was developed by Song (2002) and includes a more extensive set of variables than previous studies that have examined the relationship between travel behavior and the local built environment using the Portland data. A multinomial logit mode choice model results indicate that higher residential densities and mixed-uses promote walking behavior for nonwork activities.

 

Measuring Urban Design Qualities: An Illustrated Field Manual

Authors: Reid Ewing, Otto Clemente, Susan Handy, et al. (2005)
Report
Synopsis: This manual is the product of nearly a year and a half of research on urban design qualities related to walkability. It builds on a growing body of evidence that links the built environment to active living.This manual will provide a qualitative introduction to several key urban design qualities from the urban design literature, and then will provide guidance on how to objectively measure each quality for a typical street.
