Level crossing traffic diversion method and system

Abstract

Provided are a level crossing traffic diversion method and system. Various combination schemes are achieved by vehicle left steering (and / or straight running), so that the highly-gathering state of vehicles at a crossing is dispersed and defused, and the trafficability of the level crossing is improved. A transition zone is arranged, the shape, the position, the direction and the running rule of the transition zone are designed so that the vehicles, especially small vehicles can steer smoothly, lane changing is achieved smoothly, steering is carried out at the crossing, accordingly, the number of waiting vehicles at the crossing is reduced, and waiting time is shortened. Crossing traffic pressure is relieved by traffic diversion. Technical measures such as signal lamp control and avoiding zone arranging, so that traffic conditions are further optimized, and overall operation efficiency and vehicle trafficability are improved.

Description

technical field [0001] The invention relates to a method and a system for diverting traffic of motor vehicles at level crossings. Background technique [0002] In the background technology, the left-turning vehicle at a level crossing intersects with the lane of the oncoming through vehicle. If the left-turning vehicle and the through vehicle are released at the same time, they will easily interfere with each other when they meet at the intersection. At some intersections, left-turn and straight-going traffic signals are set up separately to avoid their mutual interference, but this will always increase the waiting time for vehicles in a certain direction, which is not conducive to the full play of the passing capacity of the intersection, thereby causing traffic congestion. [0003] Overpass bridges can solve the above problems, but overpass bridges have complex structures, occupy a lot of land, and have high construction and maintenance costs.

AI Technical Summary

Problems solved by technology

[0002] In the background technology, the left-turning vehicle at a level crossing intersects with the lanes of the oncoming straight-going vehicle. If the left-turning vehicle and the straight-going vehicle are released at the same time, they will easily interfere with each other when they meet at the intersection.

At some intersections, the left-turn and straight-going traffic signals are separately set up to avoid their mutual interference, but this will always increase the waiting time for vehicles in a certain direction, which is not conducive to the full play of the passing capacity of the intersection, and thus causes traffic congestion.

[0003] Overpass bridges can solve the above problems, but overpass bridges are complex in structure, occupy a lot of land, and have high construction and maintenance costs. Not all level crossings are suitable for transformation into overpasses

In the overpass system, there are always some vehicles driving on the bridge deck above the ground. If a traffic accident occurs and rushes down the bridge deck, more serious damage will be caused, and it may also affect the normal driving vehicles under the bridge.
