Traffic organization method for intersection with wide central isolation belts

Abstract

The invention provides a traffic organization method for an intersection with wide central isolation belts. Since the wide central isolation belts exist in the intersection, dynamically variable driving pending areas corresponding to the central isolation belts are arranged in the intersection; variable lanes are arranged in the dynamically variable driving pending areas; driving pending area signal lights are arranged in each dynamically variable driving pending area; variable split lane indication signs are arranged in front of the dynamically variable driving pending areas and are used forindicating the change of the variable lanes; when the central isolation belts are located in a road in an east-west direction; an east side driving pending area and a west side driving pending area are correspondingly arranged in the dynamically variable driving pending areas in the intersection; vehicles pass the intersection in a circulatory manner according to a set phase sequence; phases are set reasonably, and therefore, the clearing time of the intersection is compressed, and the release efficiency of the intersection is improved; and space-time optimization is realized, so that more traffic flow can pass per unit time, vehicle overflow can be avoided, and passage effectiveness can be improved.

Description

technical field [0001] The invention relates to the field of urban road traffic organization, in particular to a traffic organization method at an intersection with a wide central isolation zone. Background technique [0002] In urban traffic, the traffic capacity of road intersections directly affects and restricts the traffic efficiency of the entire road network, and becomes the bottleneck of urban traffic. How to improve the traffic efficiency of intersections is an effective means to solve traffic problems. [0003] At present, in many cities, due to reasons such as road widening, large-scale road construction, elevated bridge construction, and natural river barriers, large intersections with wide central isolation have been formed in the city. This kind of intersection is not convenient for carrying out traffic organization and becomes the difficult point of traffic because the crossing space is too large. The existing intersections are mainly organized in the followi...

AI Technical Summary

Problems solved by technology

Due to the large space at this intersection, it is not convenient for traffic organization to become a difficulty in traffic.

The existing intersections are mainly organized in the following ways: (1) The intersection is split into two small intersections for signal control, but there are often times when the traffic flow is too large and the coordination of the intersection is not properly coordinated during the peak period, and vehicles are easy to overflow at the intersection during the peak period ; (2) Carry out signal light control in the way of conventional intersections, but due to the large intersection space, the long distance of vehicles and the long time for clearing, the traffic efficiency is not high, and it is even more likely to cause traffic accidents due to untimely clearing ACCIDENT
