The Michigan Traffic Crash Facts Web site has a data query tool that gives you access to crash reports, maps and tables for crash data for 2004-2008.

I'm trying to use it to answer this question: What is the most dangerous mile of freeway in Washtenaw County? I have a guess - I-94 in Sylvan Township between mile 156 (Kalmbach Road) and 157 (Pierce Road) - but I'm looking for data to back it up.

Each red dot is one accident; the time span covered is 2004-2008.
