Travel behavior and objectively measured urban design variables: associations for adults traveling to work.

Mixed land use, residential density, street connectivity, and commute distance have been identified as potential variables affecting transport-related physical activity (TPA) behaviors. In this study, objectively measured urban design variables and TPA behaviors for adults who commuted to an occupation (n=364) were examined. Utilitarian walking and cycling for other purposes were not investigated. Commute distance was negatively associated with TPA behaviors. Logistic regression analysis identified respondents who commuted through the most connected streets were more likely to engage in TPA modes to access their occupation (OR=6.9) when compared to those traveling along the least connected. No other associations between TPA behaviors and urban variables were shown. Improved street connectivity and reduced commute distances will likely support TPA.
