Abstract

The invention discloses a traffic signal setting method for elimination of cross signal intersection left-turn phase, i.e. when a left-turn vehicle enters a signal control intersection, left turning can be realized by a method of turning right and turning around and then moving straightly or moving straightly and turning around and then turning right so that the number of the intersection signal phase and signal conversion time loss can be reduced, and an objective of enhancing intersection traffic capacity can be achieved. According to the setting method, safety hidden trouble of the intersection caused by the left-turn vehicle can be solved, and the number of the intersection signal phase and signal conversion time loss can be reduced so that intersection traffic efficiency can be substantially enhanced.

Description

technical field

[0001] The invention belongs to the field of traffic engineering, and in particular relates to a traffic signal setting method for eliminating the left-turn phase at a signal intersection. Background technique

[0002] The traditional intersection design has many conflict points and great potential safety hazards. There are 32 potential conflict points in the two-way two-lane intersection. Vehicles can collide when merging or diverging in the same lane; but the worst-case scenario occurs in the middle of an intersection, where a left-turning vehicle collides with an oncoming straight vehicle.

[0003] However, the existence of left-turn traffic flow not only brings safety problems, but also increases the number of signal phases at the intersection, increases the delay at the intersection to a certain extent, and reduces the vehicle traffic efficiency at the intersection.

[0004] Intersections are the bottleneck of the entire road network traffic operation. ...
