Embodiment Construction

[0033] The intelligent traffic management system mainly has the following components: microwave detector 6, data processing module 7, wireless communication module 8, main controller 9, computer control center 10, traffic light display board 11 and fuzzy controller 12.

[0034] The signal detected by the microwave detector 6 is input to the data processing module 7, and after the number of vehicles obtained by the data processing module 7 is input to the main controller 9, the main controller 9 combines the fuzzy controller 12 to calculate the next moment by fuzzy algorithm The length of the green light, and then send the obtained time length T back to the main controller 9; the main controller 9 outputs the received T value to the LED traffic light display board 11 in the direction of passing, and finally realizes real-time control; the computer control center 10 Connect with main controller 9 and carry out serial port communication.

[0035]The microwave detector 6 continuou...

Abstract

The invention provides a method for detecting vehicles by a microwave detector and realizing intelligent control. The method comprises the following steps of: transmitting and receiving microwaves for detecting the vehicles, and counting; inputting the obtained data into a fuzzy controller; and calculating by using a fuzzy algorithm so as to obtain the duration of a green light in the next period and intelligently distribute time to red and green lights. The invention provides a good solution for solving the problem of traffic delay caused by fixed time distribution in the conventional traffic.

Description

technical field [0001] The invention relates to a method for using microwave detection and intelligent timing of traffic lights. The microwave detector is used to detect traffic flow, and the period and duration of traffic lights are automatically adjusted according to the size of the flow, so as to realize the traffic system of intelligent control of traffic lights. technical background [0002] The Intelligent Transportation System (ITS) has been proposed in our country for many years, but the current large and medium-sized cities still cannot apply the ITS well. Due to road conditions and other reasons, the current traffic light signal change cycle is mostly fixed, lacking real-time and variability. Sometimes at the intersection, the accumulation of cars on the main road is almost saturated, but there are no vehicles on the lane, causing the cars on the main road to wait for the green light meaninglessly. At present, some large and medium-sized cities also adopt the meth...
