One of the most common locations for fatal motor vehicle–bicyclist crashes is at intersections, which inherently have many conflicts related to turning. Reducing these conflicts is a key objective in improving intersection safety across all modes. Of particular concern for bicyclists' safety at intersections are the conflicts between bicyclists travelling straight through the intersection and motor vehicle drivers making right turns and opposing left turns.
NCHRP Research Report 1125: Reducing Conflicts Between Turning Motor Vehicles and Bicycles: Decision Tool and Design Guidelines, from TRB's National Cooperative Highway Research Program, presents a decision tool and design guidelines to help highway safety practitioners reduce turning motor vehicle–bicycle conflicts at intersections.
