Crash statistics differences from 2011 to 2012
I posted this as a series of tweets on Friday night.

The issue moving forward is that we are getting more comprehensive bike crash statistics, but it is not be accompanied by more comprehensive bike traffic count data. Pressure needs to be put on IDOT and CDOT to comprehensive bike and ped counts with every traffic count/study they do from now on.
I think the comprehensiveness of the bike crash statistics has remained constant. The addition of dooring crashes to 2010 expanded them but they are stored in a different dataset (so as to not modify the main dataset’s “rule” that it only includes crashes where the automobile was moving).
What’s probably changing the most is that more people know to report crashes.
I think it’s time CDOT develops a budget for a citywide bike and pedestrian counting program that’s both static (the same 20 locations every year) and dynamic (revolving locations).
I’m a big proponent of the $200 WayCount bike and car traffic counting device. Streetsblog was going to buy one but the company didn’t obtain enough pre-orders to begin manufacturing.
