Agree you need pedestrian and traffic volumes to say anything about the risk.

I suspect that there is no accurate (or at least unbiased) recording of causation in many cases, especially the more minor injuries. They just don't have the time or resources to do it properly. Then even if it was recorded, not easy to study unless it is properly entered in a database that can be searched and keeps other stuff confidential etc, so data mining is quite a bit more practically difficult than it seems.

Related to this, I've asked the police about recording of tire condition on those slippery days where the emerg has several clients dragged out from ditches; if it is not a fatality or severe injury that may result in delayed fatality, the data collection is pretty poor, i.e they generally would NOT record if the person had snow tires or bald all seasons. I've often asked people who have been in minor crashes on these days whether they had snow tires, and there were at least a dozen no's before I got a yes. Unscientific, but given the Ontario average of using snow tires is about 30%, maybe suggests something?
