Identifying Deer Vehicle Collision Concentrations in Minnesota

Deer-vehicle collisions (DVCs) represent a significant hazard on Minnesota roads, with roughly 1,200 DVCs reported annually to the Minnesota Department of Public Safety (MnDPS) and many more going unreported. While DVCs are common across Minnesota, local variations in deer density as well as roadway characteristics and use patterns make DVCs more likely to occur on some roadways than others. Moreover, the true extent of DVC concentrations is unclear due to the high proportion of DVCs that go unreported. This report presents findings from research that (1) uses data to identify areas of DVC concentration based on the specific roadway characteristics and (2) presents a methodology to estimate DVC reporting rate across the state. This methodology is applied in a pilot study in the Duluth area, as well as in an extended search area that includes highways spread across much of outstate Minnesota to estimate the DVC reporting rate.
