Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] A kind of road crossing provided by the present invention is straight ahead and left-turn variable guiding lane signal control method, and implementation condition is as follows:

[0039] 1. Facing the road intersections of No. 3 Road, No. 4 Road and No. 5 Road, no less than 2 lanes are planned for each entrance road;

[0040] 2. For variable directional lanes, draw variable directional lane markings on the ground;

[0041] 3. The right-turn traffic flow of each entrance road is not controlled by a separate signal;

[0042] 4. The number of signal phases at each road intersection is not less than 2, and the ...

Abstract

The invention, which relates to the technical fields of traffic information and control, provides a guide lane signal control method for realizing go-straight and left turning changing at a road intersection. The method comprises: a running rule of a lane is made and a variable arrow signal light is set; main signal timing is calculated by using a Webster formula; according to a phase difference between a pre signal and a main signal, pre signal timing is determined; and a pre signal light, a lane-changing prompting mark line and a traffic sign are set to realize cyclic changing between a go-straight lane and a left turning lane for a guide lane. According to the method provided by the invention, a lane at the entrance of a road intersection is set to a viable guide lane shared by left turning and going straight; and the road resources are allocated again based on the function of pre-signal-based real-time transformation of the go-straight and left turning of the variable guide lane under the condition of the traffic flow with unbalanced layout, so that the utilization rate of the traffic facility of the road intersection is increased.

Description

technical field [0001] The invention relates to the technical field of traffic information and control, in particular to a signal control method of a guiding lane with variable straight-going and left-turning at road intersections. Background technique [0002] At present, the problem of urban traffic congestion has attracted more and more attention, seriously affecting people's travel efficiency and quality of life. Among them, the management and control of left-turn motor vehicles at road intersections is a difficult problem to solve. When there is a left-turn special lane, the existing method can basically meet the traffic demand during peak hours; but in the off-peak period, due to the reduction of left-turn traffic volume, the space utilization rate of the left-turn lane is not high, and the flow of straight traffic is large. The space resources of through lanes are very tight. How to integrate and optimize the space-time resources of road intersections is the key to im...
