*All of the specific variables could not be generated for all of the 300 bicycle crashes.
†Bicycle environments selected based on equitability among the environments and thus not a random sample.
‡Minor injury—non-incapacitating injuries.
§Severe injury—incapacitating injuries, possible injuries or killed.
¶Bicycle potential impact points, motor vehicle potential impact points, motor vehicle types and crash patterns could all equally be impacted in the four different bicycle environments.
