IoT Based Automatic Traffic Light And Speed Breaker System

The IoT-based automatic traffic light and speed breaker system is designed to enhance traffic management and road safety. It utilizes sensors and devices connected to a NodeMCU Esp8266 to detect vehicle speed and control the speed breaker. Barrier gate connected to servo motors adjust according to the traffic light, optimizing traffic flow. An emergency vehicle detection system detects sirens of emergency vehicle, turning the traffic light green and lowering barrier gate automatically. The system is connected to the cayenne IoT platform, enabling alert notification emails during the detected value is more than threshold value. Power is supplied through a solar panel during the day, a battery at night, and piezoelectric sensors will be put below the zebra crossing to generate power. And the direct supply of this generated power will be given to the street lights and etc. During adverse weather conditions as the solar panel will not be perform well. Thus, the power generated by piezoelectric sensors can be use here, so that this system can work properly at any cost. While maintenance is necessary, this work demonstrates the potential of IoT-based solutions to address real-world traffic issues and enhance road safety.
