The development of a walkability index: application to the Neighborhood Quality of Life Study

Emerging evidence supports a link between neighbourhood built environment and physical activity Systematic methodologies for characterising neighbourhood built environment are needed that take advantage of available population information such as census-level demographics Based on transportation and urban planning literatures, an integrated index for operationalising walkability using parcel-level information is proposed Validity of the walkability index is examined through travel surveys among areas examined in the Neighborhood Quality of Life Study (NQLS), a study investigating built environment correlates of adults' physical activity
