A traffic organization and signal control method for left-right dislocation intersections

Abstract

The invention discloses a traffic organization and signal control method facing a left-and-right type staggered intersection. The basic principle of the invention is to, by targeting the left-to-right type staggered intersection, optimally use the intersection staggering space and the optimally design the signal timing of the intersection on the basis of the traditional intersection design. The traffic organization and signal control method fully uses the time space resource of the intersection, reduces the purging time in a signal period, and improves the traffic capacity of the left-to-right type staggered intersection. In order to achieve that, the traffic organization and signal control method disclosed by the invention comprises steps of performing data collection on the related parameters of the intersection, performing intersection traffic organization design, performing the intersection signal optimization timing, and determining whether the intersection satisfies the preset condition and chooses the corresponding scheme.

Description

technical field [0001] The invention relates to a traffic organization and signal control method for dislocation intersections, which is used for the traffic organization and control of urban intersections and belongs to the field of traffic organization and traffic control. Background technique [0002] Dislocation intersection is a special form of intersection in urban road network. Although in my country's urban road traffic planning, it is not recommended to set up dislocation intersection due to the constraints of terrain and environment and traffic planning. Due to historical reasons, some cities still have dislocation intersections with irregular shapes. Due to the irregular shape, these dislocation intersections bring great challenges to urban traffic management and control. [0003] Generally speaking, a dislocation intersection is composed of two T-shaped intersections with a certain distance. Typical dislocation intersections can be divided into two types accordin...

Problems solved by technology

[0005] In the second method, due to the particularity of the dislocation intersection structure and the difference in traffic demand between arterial roads and intersecting roads, it is difficult to ideally implement coordinated control of dislocation intersections using the existing coordination control model

The method in the article "Research on Signal Control Scheme Optimization of Displaced Intersections in Urban Areas" cannot achieve the maximum value of two-way green waves at the same time due to the small distance between intersections. Under the method, the traffic capacity of the main road at the intersection is seriously restricted by the dislocation length of the intersection

The above two documents are designed for specific conditions (determined dislocation distance and traffic flow), and neither of them analyzes the applicable conditions and scope of their own methods, which is likely to mislead engineering practitioners
