Motor vehicle and roadway factors in pedestrian and bicyclist injuries: an examination based on emergency department data

Information on 2558 persons treated for injuries incurred while bicycling or walking was collected from eight hospital emergency departments over approximately a one-year time period. The emergency departments represented a mix of urban and suburban/rural sites in three states—California, New York, and North Carolina. The data were collected on special survey forms and included detailed information about the location of the injury event. Results show that, overall, 70% of the reported bicycle injury events and 64% of the reported pedestrian injury events did not involve a motor vehicle. In addition, 31% of the bicyclists and 53% of the pedestrians were injured in non-roadway locations such as sidewalks, parking lots, or off-road trails. Although pedestrians and bicyclists struck by motor vehicles in the roadway were generally the most seriously injured, they represented less than a third of the reported cases. Increased knowledge of non-roadway and non-motor vehicle pedestrian and bicyclist injury events can contribute to more effective program and countermeasure development to improve pedestrian and bicyclist safety.
