Density Based Traffic Congestion Control System and Emergency Vehicle Clearance

Abstract

With the growing population, traffic congestion in cities is one of the most urgent concerns. Congestion not only causes additional delay and stress for the driver but also increases fuel consumption and pollution. The existing traffic management system does not offer priority when emergency vehicles are seen because it is a timer-based traffic control system. Ambulances, fire trucks, and other emergency vehicles are unable to arrive on time because of the traffic jams on the roadways. So, in order to reduce traffic congestion in daily life, our proposed methodology measures the density of vehicles at a 4-way junction. In the absence of emergency vehicles, the proposed system gives green light automatically based on the density of vehicles on the road. The traffic light changes according to the signal emitted by the sensor. Using an RF transmitter and receiver, the signal priority is switched to the lane in which an emergency vehicle is present. This system incorporates the entire traffic system and operates in emergency scenarios to ensure quick arrival at the desired location without any delay.
