This is a continuation of my prior post, same data source. Bicyclists who get hit by cars along Maple mostly do so when riding in the roadway. Secondarily, while riding in a crosswalk. Over the period 2015-2019 (to date), there was one reportable accident involving injury to a bicyclist who was on the sidewalk, crossing a driveway along Maple Avenue.
As in the prior post, the blue dot marks the accident scene. Same minor caveat applies: The DMV only plots the accident location when they have GPS latitude and longitude data but they appear to have that information for most if not all accidents in Vienna.
