The congestion is rapidly rising across the globe because a larger number of vehicles are adding to the urban traffic every year. The rising numbers of vehicles are elevating traffic problems in the cities, which is causing the slower speeds of vehicular movements across the city roads. In this paper, the proposed model is designed to ease the urban traffic by using the smart traffic management, which is primarily based upon the contention management. The contention management is the model to determine the balanced time slots for the smoother movement of the vehicles across the squares (or light points). The dynamic time slot allocation for the particular direction is entirely based upon the vehicle density assessment mechanism, which provides the information to the time slot allocation algorithm for contention management across the city. This paper evaluates the vehicles moving on the average speed between 1 and 9 KMPH, which imitates the busiest roads of the metro cities and pushes the effort to clear as many as possible vehicles in the lowest possible time using the smart contention mechanism.
