Nowadays, developments in the Internet of Things based technologies are becoming an essential part of every aspect of human life. It has also become a norm for vehicular traffic management applications. Safe and smart ways to manage ever-increasing road traffic are essential requirements in smart cities or urban environments. Although there are various solutions for traffic management, most of them have limitations in energy efficiency, complexity, and cost. In this paper, a solution is proposed for the quick clearance of the traffic for emergency vehicles such as fire trucks, ambulances. Our approach having based on the LoRaWAN protocol, which is known for its long-range, low energy needs, low cost, scalable, and wide -area applications. LoRa devices and the TTN gateway are used to communicate with each other and to establish a green corridor for emergency vehicles. Once the green corridor is created, regular traffic is suspended for a short time to enable the emergency vehicle to cross the traffic junctions without delay. To track the location of the vehicle from the traffic signal a web page is also created. The developed system reduces the wait time for emergency vehicles and allows tracking the emergency vehicle. © 2020 IEEE.
