Road grade crossing non-conflict traffic mode arrangement and control method

Abstract

The invention relates to a communication mode arrangement related to a road signal crossing management and control and control method thereof. The invention further discloses a conflict-free communication mode arrangement for road plane crossing. On the road plane crossing, dividing the road into four crossings of an N direction crossing, an S direction crossing, a W direction crossing and an E direction crossing according to relative orientation of the plan crossing. For S direction crossing, the S direction crossing further comprises a first left-turn queuing lane and a second left-turn queuing lane. The beneficial effects of the invention lie in: based on present signal crossing communication organization, conflict of left-turn vehicle and straightly driving vehicle, that of left-turn non-power-driven vehicle and power-driven vehicle and that of right-turn vehicle and left-turn vehicle, non-power-driven vehicle and pedestrian are solved in a more prefect way.

Description

technical field [0001] The technical field of the present invention belongs to road traffic engineering, and specifically relates to a traffic mode setting and a control method related to the management and control of road signalized intersections. Background technique [0002] As the traffic node of urban roads, level intersections play a decisive role in the capacity of the urban road network. This is because level intersections are concentrated areas where vehicles with different flow directions conflict. Reducing traffic conflicts at level intersections is one of the main methods to improve the traffic capacity of urban roads. Cities often use traffic signal control and traffic channelization to reduce traffic conflicts. However, the conflict between the left-turning motor vehicle and the opposite straight-going motor vehicle has not been well resolved. At present, the most commonly used method in China is to set the waiting area for left-turning vehicles and the speci...

AI Technical Summary

Problems solved by technology

[0005] (1) If non-motor vehicles turn left in parallel with motor vehicles in the center of the road, they will be affected by the opposite going straight and the original left-turning vehicles, reducing the safety of non-motor vehicles

[0006] (2) The shape of the left-turn vehicle queuing area in the center of the intersection is irregular, which is likely to cause confusion in the queuing of vehicles

[0007] (3) The queuing area for left-turning vehicles in the center of the intersection is too close to the center of the intersection, which will affect the vertical straight traffic adjacent to the queuing area of ​​left-turning vehicles and the running of the opposite straight traffic, and will slow down the passing speed of the through vehicles.

[0008] (4) "Use six phases" to complete a signal cycle, the traffic control process is too
