Cycle crash analysis

• Accident rates per kilometer are 26 to 48 times higher for bikes than for automobiles.

• Nearly 44,000 cyclists have died in traffic crashes in the United States since 1932 (the first year in which estimates of cyclist fatalities were recorded).

• U.S. cyclists are three times more likely to be killed than German cyclists and six times more than Dutch cyclists, whether compared per-trip or per-distance travelled.

• According the British Medical Journal, the most important deterrent to riding bikes expressed by non-cyclists is fear of motor traffic.

• While motorists often accuse cyclists of being the cause of bike-car accidents, a Toronto analysis of 2572 police collision reports (Table 1) demonstrates that this is actually not the case. The most common type of crash in this study involved a motorist entering an intersection controlled by a stop sign or red light, and either failing to stop properly, or proceeding before it was safe to do so. The second most common crash type involved a motorist overtaking unsafely. The third most common type of crash is a motorist opening a door onto an oncoming cyclist. In fact, cyclists are the cause of less than 10% of bike-car accidents in this study.
