Montana has a new statewide bicycle –pedestrian advocacy group- that has incident reports on their website (just launched in Dec. 2012) in attempts to collect better data.  Here is a link:

Biking is more than just commuting and looking at one of the reports that someone posted earlier there looks to be some real under reporting going on.  As to statistical noise that all depends on the use of data and the type of analysis in being done.  I think the original question of how to over come any under reporting is still valid.

Is there that much mode shifting going on?  I thought bicycles for commuting to work were hanging in at around 1.1 to 1.5% nationally?  In which case bike crashes resulting in injuries, being a subset of a small percent, are going to represent very small numbers and percents, not much more than statistical noise...

Subject: [H+T--Friends] A Data Question

It was nice to see everyone at TRB.  While there I was in a discussion about the probably that bike crashes that result in injuries might be under represented in our crash data. Especially when you consider that a high percentage of the crashes do not involve a motor vehicle and never make it to police records. If i were trying to get a handle on this at a regional or state level are there any "non-traditional" sources of data like hospital records that can be used.  Anyone doing any work in this area?  This is becoming ever so important as we see more and mode shifting going on.
