Comparing the effects of infrastructure on bicycling injury at intersections and non-intersections using a case-crossover design.

ABSTRACT:

Background

This study examined the impact of transportation infrastructure at intersection and non-intersection locations on bicycling injury risk.

Methods

In Vancouver and Toronto, we studied adult cyclists who were injured and treated at a hospital emergency department. A case-crossover design compared the infrastructure of injury and control sites within each injured bicyclist's route. Intersection injury sites (N=210) were compared to randomly selected intersection control sites (N=272). Non-intersection injury sites (N=478) were compared to randomly selected non-intersection control sites (N=801).

Results

At intersections, the types of routes meeting and the intersection design influenced safety. Intersections of two local streets (no demarcated traffic lanes) ha
