IoT Enabled Smart Traffic System for Public and Emergency Mobility in Smart City

Transportation has existed for thousands of years. Hence, infrastructure for transportation plays a major key role in most of the metropolitan cities, leading to a change in working strategies. These changes are necessary and are made by keeping various aspects that are needed for the city and it results in being a smart city. Due to industrial establishments, IT parks and other related reasons the population density of the urban area increases in vast numbers. This in turn shoots in the number of vehicles in the urban as commutation resulting in the traffic congestions. The present road infrastructures are not able to appease the rapidly increasing number of automotive mobility on the roads. One of the major infrastructures for mobility is traffic signal management. Currently, the conventional method of the signal controlling that fails to a larger extent in managing the time. A modern-era solution is proposed here by employing the Internet of Things (IoT) that was achieved here by integrating several sensors to the microcontroller. The proposed solutions are favorable effects in reduction of delay, fuel consumption, wastage of energy, pollution from vehicles. To validate the proposed approach a prototype model was demonstrated and it was specifically designed for public and emergency vehicles such as fire brigade and ambulance that had to be needed highest priority at the time of mobility. Hence, a completely automated and intelligent IoT based traffic system is developed and proposed here.
