• Abstract:
  "Using a parcel-level database of crash incidence and urban form developed for the San Antonio-Bexar
  
  County metropolitan region, this study examined how urban form-related variables affect the incidence of
  
  crashes involving pedestrians, bicyclists, and motorists. Arterial thoroughfares, strip commercial uses, and
  
  big box stores—which include design features expressly intended to support automobile travel—were
  
  found to be associated with significant increases in crashes involving pedestrians, bicyclists, and motorists
  
  alike. Population density was found to be associated with increased crash incidence among pedestrians,
  
  although this is likely a function of increased crash exposure due to the higher levels of pedestrian activity
  
  occurring in higher-density environments. The presence of pedestrian-scaled commercial and retail uses,
  
  which is likewise associated with increased pedestrian travel, was nonetheless found to be associated with
  
  statistically significant reductions in the incidence of multiple-vehicle, fixed-object, and pedestrian crashes.
  
  Given that the developmental risk factors that affect pedestrians, cyclists, and motorists proved to be
  
  largely the same, this report outlines potential strategies for addressing urban crash incidence in a
  
  comprehensive, multimodal manner."
