Problems solved by technology

[0006] The object of the present invention is to solve the problems mentioned above, in order to solve the problems of secondary parking and potential safety hazards, improve the traffic capacity of left-turn vehicles and take into account the overall operating efficiency of the intersection, and propose a An intersection control method based on main and pre-signal phase coordination, using intermittent lanes, and the length of the intermittent area is not limited by the traffic flow at the intersection and the length of the road, which can maximize the capacity of the intersection and evacuate vehicles inside the intersection. Reduce the number of stops, reduce vehicle delay costs and fuel consumption costs at intersections

Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the drawings, so that those skilled in the art can better understand the present invention.

[0023] The present invention is mainly based on the intermittent lane, and the intermittent lane signal control based on the intersection of the waiting area means that the leftmost straight lane is retreated a certain distance as the intermittent area, and the left-turn traffic flow and the straight traffic flow use the signal between the pre-signal and the main signal. The coordinated control of the vehicle enters the intermittent zone in an orderly manner and passes through the intersection, and the remaining lanes leave the intersection according to the guidance of the main signal. Taking a four-lane intersection as an example, from left to right are left-turn special lanes, intermittent lanes, straight-going special lanes, and right-turn spe...

Abstract

The invention belongs to the technical field of traffic design and control, and particularly relates to an intersection signal control method adopting intermittent lanes. The method is used for a multi-lane intersection, multiple lanes at least comprise a left-turn special lane and a straight special lane, and the straight special lane adjacent to the left-turn special lane is set as an intermittent lane; according to the arrangement method of the intermittent lanes, intermittent area parking lines are arranged on the corresponding straight-going special lanes, the area between the intermittent area parking lines and the intersection parking lines is defined as an intermittent area, wherein the intermittent area refers to that left-turning vehicles and straight-going vehicles alternately enter under signal control. The method can reduce the problem of secondary parking at the intersection of the waiting area, gives consideration to the overall traffic efficiency of the intersection, and can be suitable for various traffic conditions.

Description

technical field [0001] The invention belongs to the technical field of traffic design and control, in particular to an intersection signal control method using intermittent lanes. Background technique [0002] Intersection geometric design and signal coordination control optimization are the main means for traffic engineers to solve urban traffic congestion, improve urban road traffic efficiency, and reduce travel delays and air pollution. As a key factor affecting the operational efficiency of intersections, left-turning vehicles, how to improve lane utilization efficiency by coordinating the ratio of left-turning phase and straight-going phase duration, thereby reducing the number of parking times and vehicle delays at intersections, is still a hot spot in the current traffic field. [0003] In order to eliminate the impact of left-turning vehicles, traditional methods have proposed intersection geometric design schemes such as symmetrical intersections, U-turns, super str...
