Blogger M. V. Jantzen has taken bike crash data compiled by Arlington County and put them online in a very impressive looking mapping system (as shown above).
Arlington County has released its own set of bicycle accident data. There were 227 incidents recorded from January 1, 2010 to December 31, 2012 (though the first recorded accident wasn’t until March 1, 2010). That’s 6.3 reported incidents a month. I’ve made a map for them, the Arlington Bicycle Accidents Stat Mapper.Locally, some bike crashes are shown, but far less than elsewhere in the County.
