Traffic Impacts of Bicycle FacilitiesStatus: CompleteReport Date: 06/21/2017 Summary: Researchers evaluated bicycle and motor vehicle interactions at nine locations in Duluth, Mankato, Minneapolis and St. Paul. Results show that on shared roadways without clearly marked bicycle facilities, drivers are more inclined to pass bicyclists, encroach on other traffic lanes or line up behind bicyclists than they are on roadways with clearly marked facilities. Researchers recommend that where space allows, bicycle facilities should be striped or buffered to reduce interactions between vehicles and bicycles and to improve traffic flow.
