Intelligent traffic control system and method based on sensor network and lifting guardrail

Abstract

The invention provides an intelligent traffic control system based on a sensor network and a lifting guardrail, the intelligent traffic control system comprises a traffic flow detecting device, a traffic signal instrument and a plurality of automatic lifting piles, the traffic flow detecting device comprises a signal collecting unit and a gathering unit, the signal collecting unit and the gathering unit are both buried below a traffic road surface, the automatic lifting piles are arranged above the traffic road surface, an output end of the signal collecting unit is connected with an input endof the gathering unit, the output end of the gathering unit is connected with the traffic signal instrument, the traffic signal instrument is connected with the automatic lifting piles, the signal collecting unit detects metal disturbance that is caused when a vehicle passes through the traffic road surface, and transmits a metal disturbance signal to the gathering unit, the gathering unit mergesthe received metal disturbance signals and transmits a merged metal disturbance signal to the traffic signal instrument, and the traffic signal instrument judges the traffic flow of a target road section according to the merged metal disturbance signal and controls the ascending and descending of the automatic lifting piles according to the traffic flow information.

Description

technical field [0001] The invention relates to the field of intelligent traffic systems, in particular to an intelligent traffic control system and method based on a sensor network and a lifting guardrail. Background technique [0002] At present, the contradiction between limited urban road resources and the ever-growing vehicle market is becoming more and more obvious. In order to cope with the increasingly congested traffic environment and the demand for urban growth, the method of changing the number of lanes through "zipper cars" has existed and been put into operation. . The traffic department also specially marks tidal lanes on individual roads, stipulates the time of passing in the direction, or restricts the number of vehicles and other means. At the same time, the use of traffic lights to intelligently control traffic flow and alleviate congestion is also the main means of most intelligent transportation systems. [0003] However, these main methods have disadva...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides an intelligent traffic control system and method based on sensor networks and lifting guardrails, which are mainly used to alleviate urban traffic congestion and solve the problems of fragile, high maintenance costs, labor-intensive and Problems such as untimely regulation and unclear prompts caused by passive acceptance of unexpected traffic changes
