Factors Affecting Vehicle Passing Distance and Encroachments While Overtaking Cyclists

State and local governments are interested in providing safe and comfortable bicycle infrastructure that encourages cycling as a mode of transportation. After Hennepin County, Minnesota, USA acquired C3FT bike-mounted radars, they collaborated with the University of Minnesota on a study of vehicle passing behavior on the county bicycle network. This article presents the results of that study, which used two measures of relative safety: (1) vehicle passing distance (VPD) when overtaking cyclists, and (2) encroachments. Minnesota statute requires a minimum VPD of 3 feet (36 inches) while passing a cyclist. Anything less is an encroachment. This report investigates vehicular encroachment and VPD while overtaking cyclists on different bicycle facilities across seven roadways in Hennepin County
