SAFER LEFT TURN SIGNING

ANALYSIS REVEALED THAT THE LEFT-TURN MANEUVER BECOMES UNSAFE WHEN INSUFFICIENT GAPS IN ONCOMING TRAFFIC OCCUR, AND WHEN INFORMATION AVAILABLE TO BOTH STREAMS IS INSUFFICIENT. A SYSTEM OF SIGNS WAS DEVELOPED TO INDICATE TO THE ONCOMING DRIVER WHEN LEFT TURNING WAS PERMISSIBLE, AND TO INFORM THE TURNING DRIVER OF THE PRESENCE OF ADVANCED GREEN SIGNAL OPERATION.
