Abstract

The bike-auto accidents in Davis, California, a city with a long-standing bike-lane system, were classified in 10 accident categories. The relative frequency of accidents in each category in Davis was compared to that in Santa Barbara, but comparable community without bike lanes. Within Davis, streets with bike lanes were compared to those without bike lanes using the same categories. Three accident tights that were judged to be uninfluenced by bike lanes were used as a standard for determining the effect of bike lanes on the absolute frequency of other classes. Relative to those three classes of accidents, rates were reduced by bike lanes in six accident classes in increased in one class. The frequency of accidents influenced by bike lanes was reduced by 53% overall, and the frequency of all accident tights combined was reduced by 31% on bike lanes, demonstrating a positive effect of bike lanes on safety.
