Intersection bidirectional congestion intelligent induction control system and method

Abstract

The invention discloses an intersection bidirectional congestion intelligent induction control system and method. The system comprises a vehicle queuing length geomagnetic detector, an intersection central congestion overflow geomagnetic detector, an LED warning lamp, a signal lamp, a wireless geomagnetic node information receiving and controlling device and an intelligent annunciator. In intersection bidirectional congestion intelligent induction control system and method, an intelligent control mode which is simple in logic, intelligent in process and easy to implement can be provided for the bidirectional congestion-prone intersection mainly according to queuing length and overflow state data monitored in real time under the control rule of the intelligent induction and control system; risks of bidirectional congestion overflow and vehicle intertwining at the intersection are reduced, the vehicle passing efficiency in different vehicle flow directions is improved, and the intelligence of intersection signal control is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic control, and in particular relates to an intelligent sensing control system and method for two-way congestion at an intersection. Background technique [0002] With the rapid increase of road traffic volume, urban road traffic congestion is becoming more and more serious. In some intersections, vehicles will blindly "grab the road" in the last few seconds of the signal lights. Especially at intersections where the two-way traffic flow is relatively large and the distance is relatively close, the traffic flow in one direction (for example: east-west direction) is relatively large, and the queuing traffic flow in this direction has not been released within the entire green light duration. Due to the large traffic flow , the traffic queue length at the next intersection has reached the intersection, and some vehicles in the east-west direction will "grab into the intersection" in the last...

AI Technical Summary

Problems solved by technology

The two-way traffic flow "rushing in" can easily cause the intersection overflow phenomenon, and the vehicles pouring into the intersection will appear in a state of multiple interweaving horizontally and vertically, causing vehicles in two directions to intertwine and entangle in the intersection, and refuse to give way to each other. Impossible to pass through, making the signal control of the entire intersection invalid, and the intersection begins to be congested in both directions, completely entering a paralyzed state, and the traffic efficiency is reduced
