The guys from Slow Streets – Darren Proulx and Samuel Baron – have some new data:
Vancouver Vehicular Collisions Involving People Walking and Cycling 2009-2013
Slow Streets found that larger roads widths were correlated with higher rates of collisions between vehicles and people walking and cycling.
Utilizing data from ICBC’s pedestrian and cycling collisions, Slow Streets compares the number of vehicular collisions with road width in the City of Vancouver.

Slow Streets also created an interactive map so that you can examine these numbers yourself. You can customize the graph and averages by selecting a specific group of intersections. Selecting specific intersections will also show you the breakdown of walking versus cycling collisions. You can also retrieve the raw data and coordinates for any selection of intersections.
To view the interactive map, go here.
The number of collisions may be higher on roads with 4 or 6 lanes because there are more cars, and potentially more pedestrians and cyclists, available to collide with each other. The report mentions rates of collisions, but only provides total and average numbers of collisions. To compare apples to apples, the volume of vehicle, pedestrian and cycling traffic should be factored in.
