Abstract

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.

Description

technical field

[0001] The invention relates to a method for improving the traffic capacity of a cross-shaped intersection of urban roads, in particular to a collaborative design method for diagonal pedestrian crossings and motor vehicles turning left at the cross-shaped intersection. Background technique

[0002] Motor vehicles turning left at urban cross-shaped intersections are likely to conflict with pedestrians, which affects the efficiency and safety of intersections. Vehicles turning left at urban cross-shaped intersections are more likely to cross with pedestrians crossing the street, which affects the efficiency and safety of motor vehicles and pedestrians. When the traffic volume of motor vehicles turning left at the intersection is large, it will cause pedestrians to cross the street sideways and wait for the red light for too long, which will induce pedestrians to "hit the red light" phenomenon; When crossing the street, you need to wait for the traffic lights t...
