IoT based Intelligent Traffic Signal System for Emergency vehicles

the population of India is growing, the number of vehicles is also increasing tremendously. This makes it difficult to manage time and priority of emergency vehicles like ambulance, fire brigade, police vehicles etc. The proposed model basically works on properly managing the traffic and clear the congestion of vehicles in order to make clear way for emergency vehicles and reduce their effort and time to reach the destination. Some researchers have already worked on proper traffic management by identifying the priority of the vehicles, still their work is not enough to solve the problem completely. So to address this traffic congestion issue an idea has been proposed in this paper which includes use of IoT which helps to overcome the traffic congestion for emergency vehicles. This proposed model includes managing traffic signals using devices like Raspberry PI, Node MCU, RFID Tag and Reader in such a way that when an emergency vehicle arrives, the signal changes by properly communicating with the sensors in vehicle and signal.
