Balance bridge at entrance and exit of main and auxiliary roads and method for easing traffic jam

Abstract

The invention discloses a balance bridge at an entrance and an exit for main and auxiliary roads and a method for easing a traffic jam of the roads, the balance bridge at the entrance and the exit for the main and the auxiliary roads comprises an exit channel, an entrance channel and a balance bridge body, and the method comprises the following steps: (a) setting a driving channel under the bridge for communicating the main road with the auxiliary road; (b) setting the balance bridge body bestriding the driving channel under the bridge above the driving channel under the bridge; (c) setting abridge surface driving channel from the main road to the auxiliary road or from the auxiliary road to the main road along the upper surface of the balance bridge body; (d) enabling one of the bridge surface driving channel and the driving cannel under the bridge to be the exit channel which can only enable vehicles to drive from the main road to the auxiliary road along the vehicle driving direction, and enabling the other one to be the entrance channel which can only enable the vehicles to drive from the auxiliary road to the main road along the vehicle driving direction; and (e) enabling the vehicles to drive into the auxiliary road from the exit channel, and enabling the vehicles to drive into the main road from the entrance channel. By adopting the balance bridge and the method, the number of nodes under the jam along a demarcation line of the main road and the auxiliary road can be effectively reduced, and the status of the traffic jam of the roads can be effectively eased under the situation of not reducing the passing efficiency of entering into and exiting from the main road and / or the auxiliary road.

Description

technical field [0001] The invention relates to a road traffic facility, in particular to a balance bridge at the entrance and exit of main and auxiliary roads for alleviating traffic congestion on urban roads. Background technique [0002] like figure 1 As shown, in the prior art, in order to make it easier for vehicles traveling on the main road to enter and exit the auxiliary road and vehicles traveling on the auxiliary road to enter and exit the main road, exits that can only enter the auxiliary road from the main road and exits that can only enter the auxiliary road from the main road are provided at certain distances. The entrance of the auxiliary road into the main road, the exit and the entrance are set at intervals to facilitate the entry and exit of vehicles on the main road. [0003] At the exit: vehicles on the main road that need to enter the side road merge into the lane near the exit to enter the side road, while vehicles on the main road that do not need to ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, at the exit and entrance, there will be congestion due to the temporary reduction of the forward driving lane and the merging of vehicles; while there will be exits or entrances at regular intervals along the junction of the main road and the auxiliary road, so that along the main road There will be a congestion node every certain distance at the junction with the auxiliary road, which greatly reduces the traffic efficiency of the road; this is an important reason for urban road traffic congestion, especially in big cities such as Beijing and Shanghai.
