Interactive map shows car collisions with pedestrians and cyclists

While any number of collisions between cars and pedestrians or cyclists is too many, Stittsville has a relatively low number compared to other areas in Ottawa.

The map was created by Alex deVries, vice-president of Citizens for Safe Cycling. It’s an interactive heat map on their web site that shows car-pedestrian and car-cyclist collisions in Ottawa over ten years, from 2004 to 2013.  You can check it out here…

“Over time, the absolute number of reported collisions involving pedestrians or cyclists has remained relatively flat, even though both Ottawa’s population and the popularity of cycling have increased dramatically over these years,” they note. “The number of collisions for cyclists, relative to population and the growth in cycling, is actually down.”

StittsvilleCentral.ca asked deVries about why he created the map. Here’s his reply:

I created the site to provide some information people could use to understand patterns in collisions of cyclists and pedestrians. City staff are using this tool to understand where and when collisions occur.

There were several surprises in this to me:
– the location of pedestrian and cycling collisions are not the same; in Stittsville, there’s quite a few collisions on Stittsville Main St, but the cyclist collisions are more likely to be at intersections. Pedestrian collisions are where there aren’t cross-walks.
– cycling collisions tend to be near bridges and near strip malls, and where there are no bicycle lanes.
– there’s an impression that there are more cycling collisions now more than ever. This isn’t true; the number of reported collisions is roughly flat, despite a 40% increase in cycling and crowing population.
– the worst place in the city for cycling collisions is Bank St. near Billings Bridge. It is about twice as bad as the next locations (on Rideau St. and Montreal Rd).
