Data from Only State that Tracks Dooring Show Its Big Problem
Friday, September 28, 2012 - 02:38 PM
Here's a little update on how prevalent "dooring" accidents are: very.
When we reported on NYC's new initiative to stop taxi passengers from hurting cyclists by reminding people not to open the car door when a bike rider is passing, we mentioned that Illinois is -- we think -- the only state to track dooring accidents as its own category. The Illinois Department of Transportation didn't get back to us with a request for dooring data, but Chicago writer Steven Vance did and he has access to IDOT's Data Mart, their online transpo data distribution site. He generously sent over the dooring data for Chicago, but also crunched the numbers on his site, Grid Chicago.
The results are pretty shocking. In 2011, one in five bike crashes were caused by dooring.
- In 2010, there were 127 reported dooring crashes, for a rate of 0.35 doorings per day. Doorings made up 7.25% of all reported bike crashes.
- In 2011, there were 344 reported dooring crashes, for a rate of 0.94 doorings per day. Doorings made up 19.7% of all reported bike crashes.
- In 2012, up until August 29, 2012, there were 132 reported dooring crashes, for a rate of 0.55 doorings per day. Data for non-dooring crashes is incomplete and excluded.
