Where bike accidents happen most often in Toronto

The Globe did a great thing today—they got, and mapped, twenty-five years of cycling collision data. And then they released the data, which makes it much easier for people like me to tell you, say, the total number of reported collisions on any street you can name. Which is what I’m going to do here.

Here are some of the Toronto streets that stuck out from a glance at the map as especially accident-heavy, as well as the number of collisions those streets have per kilometre, with the obvious caveat that these counts don’t necessarily reflect how safe or dangerous a street is (College–Carlton is the street where the greatest number of cycling accidents occur per kilometre, but a lot of cyclists use it), and also that my per-kilometre counts are rough because I used this to determine how long any given street is within Toronto.
