abstract="The realization of the many benefits of bicycling will not be achieved in American regions until safer bike infrastructure and bicycling conditions are presented to a more general population. The Phoenix region--one of the nation's most populous--has sought policies and programs to increase bicycling rates. Yet, the region continues to have a small mode share, underscoring a need to motivate population-level bicycling adoption. This study examines 2015-2019 bicycle-vehicle crash data to identify those macro-level factors associated with bicycle-vehicle crashes and a subset of crashes where a serious injury or fatality occurred. Specifically, the effects of a robust set of socioeconomic and built environment factors, measured at three hexagon spatial extents, in negative binomial and spatial Durbin models were estimated for the two crash outcomes. <br><br>RESULTS show denser zones with a traditional network design experienced more bicyclist-involved crashes, as did zones with a higher percentage of low-income households and working-age adults. <br><br>FINDINGS, which also found spatial clustering of total and severe bicyclist-involved crashes, suggest that the targeted provision of safer bike infrastructure and a more complete network in zones exhibiting certain macro-level attributes holds promise in creating bike-friendly conditions that generate more utilitarian and recreational bicycling throughout the region.<p /> <p>Language: en</p>",
