Bike collisions by year in Toronto

Details

Category: bikeTO

The Globe and Mail put up a web map back in January of bicycle accidents over the last 25 years (1986 - 2010).

I grabbed the data from buzzdata because I was interested in looking at aggregating the data into a heat map and looking at the year over year trends.

Click through on the map below to see how bike collision intensity in the city has been changing over the last 25 years.

You can click on each square to see the year over year trend up to 2010.  

One big problem with this view is that it isn't corrected for the number of cyclists on the road.  Sure, there are more accidents downtown than in the Annex, but is that because the bike couriers are flinging themselves around like lunatics or because there are more cyclists? Good question.
