A traffic organization method for intersections with wide medians

Abstract

The invention provides a method for organizing traffic at intersections with wide central isolation strips, which utilizes the space of road intersections generated by the existence of central isolation strips to set up dynamic variable waiting areas, and sets corresponding central isolation strips in road intersections. There are dynamic variable waiting areas, and variable lanes are set in the dynamic variable waiting areas, each dynamic variable waiting area is respectively equipped with waiting area signal lights, and variable lanes are set in front of the dynamic variable waiting areas. Lane dividing signs are used to guide the change of variable lanes. When the central isolation zone is located in the middle of the road in the east-west direction, the dynamic variable waiting area in the road intersection is correspondingly set as the east waiting area and the west waiting area. Vehicles circulate in the order of the set phases. Through reasonable phase settings, the intersection clearing time is compressed, and the efficiency of intersection clearance is improved. Through space-time optimization, the goal of passing more traffic flow per unit time is achieved, vehicle overflow is avoided, and traffic flow is improved. efficiency.

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
