The invention relates to a design method for cooperating the
street crossing of opposite-angle pedestrians and the left turning of a motor vehicle at an intersection. According to the method, firstly, traffic island chamfer parts (2) of angle-turning traffic islands (1) in the opposite-angle direction of the intersection are connected with each other, and two zebra crossings (5) with the opposite angles being crossed are arranged so that the opposite-angle pedestrians can pass through; a central
pedestrian safety island (7) is arranged in the center of the intersection, and a left turning guide line (6) of the motor vehicle is arranged in the intersection, so as to ensure the separation of motor vehicles and non-motor vehicles at the intersection and guarantee the secondary opposite-angle
street crossing safety of the pedestrians; meanwhile,
pedestrian street-crossing traffic lights (4) in the opposite-angle direction are arranged on the angle-turning traffic islands (1) at the intersection, so that the
street crossing of the opposite-angle pedestrians and the left-turning street crossing of the motor vehicles are controlled together with
signal phases cooperatively. According to the design method, the effective road passing-through area of the intersection at a left-turning phase can be effectively enlarged, the
delay of the street crossing of the opposite-angle pedestrians can be reduced, and the
traffic conflict can be decreased. The design method is suitable for the intersection of an
urban road which is large in the flow of the left-turning motor vehicles, large in the demand of opposite-angle street crossing and lower in the speed of the vehicles.
