City traffic management model using Wireless Sensor Networks

Road network of a region is an important mean of overall development. To manage the traffic in a city environment is a key factor for the city authority. In this perspective, reducing the road traffic congestion is a significant challenge. In this paper, a dynamic mathematical model for managing road traffic in important intersections of a city by reducing congestion is presented. This system will be built based on wireless sensor network which will detect the congestion on the road and broadcast the congestion information to the drivers in order to detour for avoiding congestion. Matlab simulation of this proposed model was performed with traffic generated following Poisson Distribution for twelve selected important intersections of a city and cost function was estimated for the generated traffic. Simulation results show that this traffic scheme succeeds in reducing the congestion compared to the traffic situation without this scheme.
