Smart Traffic Management System Using Arduino and Sound Sensor

Even today in some places the traffic drivers are still dependent on the traffic police to control the traffic based on the traffic density. Their had been a lot of research for controlling the traffic automatically like using image processing technique, IR sensors, laser sensors. These are cost efficient and are complex. So in order to avoid the traffic congestion we use Arduino and ultrasonic sensor which is simple and less cost. Ultrasonic sensor is a type of sensor, it measures the distance of an object with the help of transducer and receiver. Arduino is referred as a microcontroller. It available for both hardware and software companies, projects and it is also used to manufacture a single board of microcontroller or the microcontroller kits for the building of the digital devices. Arduino device is mainly used to collect the signals from the ultrasonic sensors and these signals of sensors again interacts with other Arduino device which helps in handling traffic light signals.
