Analysis of Traffic Conflicts Between Right-Turning Vehicles and Pedestrians or Cyclists at an Urban Signalized Intersection

In Japan, where vehicles travel on the left side of the road (i.e., right turns correspond to left turns in the U.S.), right turns have the potential to put a heavy work load on drivers at signalized intersections in urban areas, because the driver has to judge the headway in oncoming traffic while avoiding pedestrians in the crosswalk. This study investigates conflicts between the right-turning vehicle and pedestrians/cyclists at such intersections. We conducted an observation to measure the the driverfs avoidance behavior, and evaluated the conflicts with the pedestrian/cyclist in terms of time-lag which is defined as the time interval between the time when the right-turning vehicle reaches the conflict point and the time when the pedestrian/cyclist reaches the conflict point. This study found that the time lag is re-evaluated by the driver during the right turn and that the driver constantly took low risk driving behavior to avoid the conflict with the pedestrian/cyclist at the actual intersection.
