Dynamic Traffic Light Switching based on Traffic Density

Abstract

In recent years, the amount of traffic on the roads has risendramatically. The signals in the new Traffic Light system differaccording to preset time intervals. They do not change according to the amount of traffic. Waiting times are longer and fuel consumption is higher due to fixed time intervals. Furthermore, emergency vehicles are not prioritised in these traffic networks. Emergency vehicles will find it difficult to cross the traffic signal during peak hours. We suggest a system that allows for dynamic switching between traffic lights as well as emergency vehicle preemption to increase traffic lightcontrol performance. A microcontroller with an infrared sensor is used to monitor traffic lights. A microphone is also built into themicrocontroller to identify emergency vehicles. As a result, traffic signal optimization improves the flow of traffic.
