A system and method for intelligently controlling traffic lights through sound decibels

Abstract

The invention provides a system for intelligently controlling traffic lights through decibels. The invention also provides a method for intelligently controlling traffic lights through decibels, based on the above system. The system for intelligently controlling traffic lights through decibels, and the method thereof can acquire the current noise through a noise measuring unit, can determine the current road condition through the noise condition, and can start a new traffic signal light change scheme when the estimated road condition is crowded, so that jam of a crossing can be eliminated and the pressure of traffic polices can be reduced.

Description

technical field [0001] The present invention relates to a system for controlling traffic lights by detecting noise decibels and a method adopted by the system. Background technique [0002] With the rapid development of urbanization, more and more urban diseases have emerged, among which the most troublesome thing for people is traffic congestion. One of the biggest causes of traffic congestion is failure of traffic lights at intersections. Due to the large traffic flow during peak hours, the traffic light scheme designed according to usual times often cannot meet the needs of peak hours, resulting in traffic congestion. [0003] For example: For a certain intersection, the green lights in the east-west direction and the north-south direction are alternately lit, and each time the light is on for 30 seconds. This kind of traffic plan can meet the demand when the road is not congested, but when the road is congested, if the east-west road is congested and the green light in...

Problems solved by technology

For example: the utility model patent with the publication number CN201946122 discloses a wind-power complementary traffic signal light, the purpose of which is to solve the current problems that the traffic signal lights cannot be used normally and consume a large amount of energy, and provide a combination of wind power and solar energy. The combination of electric energy can ensure that the traffic signal lights are not interrupted during power outages, and can save a lot of electric energy.
