Abstract:

Motor vehicle crash records and/or emergency room treatments are the primary focus of most bicycle crash research which misses the 70% of crashes not in these two categories. This study began with a personal experience, a bicycle crash that did not involve a motor vehicle, did not necessitate an emergency room visit, was therefore not reportable and represented an example of the majority of bicycle crashes. An electronic survey was distributed nationally to bicycle clubs and bicyclists requesting details of non-motor vehicle bicycle crashes of which 273 were received. Survey distribution resulted and data showed methodological bias that limits study generalizability to all bicyclists, but provides valuable initial causal factor details for the 90% of bicycle crashes that do not involve motor vehicles. The major causes for non-motor vehicle bicycle crashes and the percentage they represent were found to be rider inattention (28%), other riders (23%), debris (22%), excessive speed (21%), grades (19%), cracks and potholes (14%) and turning sharply (11%). These causal factors are in complete contrast to the top eight bike crash causes presented by the FHWA university level bicycle transportation course. This contrast highlights the difference in causal factors of motor vehicle and non-motor vehicle involved bicycle crashes. It is possible therefore that a renewed examination of bicycle safety (including both reported and unreported, motor vehicle and non-motor vehicle, and all severity types of crashes) based in part on the results of this research would lead to a need to modify safety policy.
