Expressway exit alternative passing control method and control device

Abstract

The invention discloses an expressway exit alternative passing control method and control device. The method comprises the steps of: setting a stop line and signal lamps at an upstream change lane of a side road at the expressway exit for each lane; setting a detection device which is used for detecting a vehicle congestion condition in front of the stop line for each lane; and transmitting vehicle congestion signals detected by the detection device to a signal machine so that the signal machine controls the signal lamps according to the received vehicle congestion signals so as to control each lane to be in a normal state or an alternative passing state. According to the method and device disclosed by the invention, the side road congestion condition is detected by the detector, corresponding control is performed according to the detection result, and congestion problem of the expressway exit can be solved efficiently.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a control method and a control device for alternate release at expressway exits. Background technique [0002] The urban expressway serves for long-distance travel and can guide cross-regional traffic. It is the main traffic connection channel between the central area and the peripheral area, between the central city and the new city, and between the main road of the central city and the radial road outside the city. The urban expressway is a relatively independent system. It intersects with other urban roads as interchanges. Auxiliary roads should be set up on both sides of the expressway exit to connect the entrances and exits on both sides, so as to provide convenience for vehicles entering and exiting the expressway. [0003] With the continuous growth of automobile traffic demand, the traffic congestion phenomenon of the expressway system is also very serious, and ...

AI Technical Summary

Problems solved by technology

Especially at the bottleneck of the upstream road on the auxiliary road at the exit of the expressway, because multi-lane vehicles meet and change lanes here, when the traffic flow on the auxiliary road is large, the vehicles on the auxiliary road near the expressway exit and the main road are seriously intertwined, the traffic order is chaotic, and there are potential safety hazards Larger, which in turn makes the expressway congestion serious, and the expressway cannot play a fast role

The existing traffic control for expressway exits is relatively simple. Generally, the signal control method at urban intersections is directly transplanted, which cannot effectively solve the congestion problem near the expressway exit and the expressway.
