基于Arduino的智能交通信号灯设计

AbstractIntelligent traffic control system play an important role in the trafficcontrol system.In order to better control the transportation system,alleviate traffic pressure.This paper designs the intelligent traffic lightbased on Arduino,According to the traffic flow crossing detection,trafficlights to achieve automatic switching function.Traffic signal system based on the Arduino use ATmega328 microcontroller as the main control chip of the controller.The system canachieve five basic and innovative features:Firstly,digital tube can achieve countdown;Secondly,the digital lights can display;Thirdly,it also can realize the flow rate of traffic detection andadjustment of the passage of time,it count the number of the flow rate oftraffic up through the pressure sensor for traffic,when it comes to acertain value,the interrupt latency of the program will be executed;Fourthly,this design also combines with the use of infrared sensorand the buzzer to be an alarm circuit,when the red light of the pedestrianissues a security alert.Ⅲ
