AbstractIn the United States, the transportation sector was responsible for 28% of 2016 GHG emissions—the largest contribution of any industry (U.S. EPA, 2018). To reduce dependence on fossil fuels and mitigate their effects, active modes of transportation, like walking, need be planned for. This study provides an overview of walking in Tucson, AZ and subsequent guidance for future development through a) an assessment of walk-mode splits, b) a survey on residential preferences for walking, and c) a built environment case study analysis. It found that walking constituted 11% of all trips, compared to motorized vehicles, which accounted for more than 80% of all trips. Percentage of respondent walk and car trips varied significantly by income and trip purpose. Both Tucson residents and existing literature identified destination proximity as the most important built environment factor considered in deciding to walk. A complete streets project that incorporated many built environment features found to improve walkability (e.g., street connectivity, accessibility, walking infrastructure) but failed to account for destination proximity had little impact of walking behavior. To better promote walkability in Tucson, emphasis on coordination between transportation and land use planning and connection of walkability to social and cultural values is necessary.
