A review on smart traffic control system using modern approaches

In India, emergency vehicles encounter a multitude of obstacles that significantly lengthen the time it takes to reach the intended location. The increasing volume of traffic and the lack of a standardised method for regulating it are major contributors to this problem. Mainly, we want to make sure that the crisis car can get where it has to go as quickly as possible, relative to how long it usually takes an emergency vehicle to get there. A variety of techniques are employed, including global positioning system (GPS) tracking, radio frequency identification (RFID) tags that confirm the arrival and movements of the crisis vehicle through a traffic signal and alert the control system to turn the signal green for an emergency passage, and the utilisation of ultrasonic sensors and cameras to determine the density of the traffic flow and transmit the information to turn the signal green.
