ABSTRACT: This project aims at designing THE DENSITY BASED TRAFFIC CONTROL SYSTEM in which the traffic signal is changed according to traffic density using sensors. In recent times the traffic congestion has become a severe problem in many metropolitan cities. So, in this project we change the traditional traffic system or time-based traffic system to density-based traffic control system. Present day traffic system is based on the time based. This may render inefficient if one lane is operational than other. As the number of vehicles increase constantly and current resources & infrastructure being limited. This type of project is particularly important for future. Our project will demonstrate the optimization of traffic light using wireless sensors. With multiple junctions, the complexity increases as the state of one light influence the flow of traffic that reflects on many other nodes
