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.

 

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.

 

Turning Highways into Main Streets: Two Innovations in Planning Methodology

Authors: Reid Ewing, Michael R. King, Stephen Raudenbush, and Otto Jose Clemente (2005)
Report
Synopsis: Visual preference surveys have become a popular tool among planning practitioners. By tapping visual media, such surveys help to illustrate physical design alternatives in ways that words, maps, and other media cannot. They have found applications in visioning projects, design charrettes, and other physical planning activities with heavy public involvement. With little additional effort, a visual preference survey can be restructured as a visual assessment study, which provides more useful information. Confounding variables can be controlled, and underlying qualities that cause certain scenes to be preferred can be identified. This article reports on a visual assessment study of state highways, identifying the physical features that can make them into main streets.
