Design and Analysis of a Two Stage Traffic Light System Using Fuzzy Logic

Traffic congestion of streets and roads constitutes a critical problem which is aggravated by the rise in the number of vehicles and by greater urbanization. The slow pace in the development of new highways and roads and public opposition to the widening of existing streets in some locations has forced the city managers to optimally use the existing infrastructures in order to effectively manage the flow of traffic. Moreover the loss of valuable time during traffic congestion can directly affect the production, productivity, performance and the utilization of fuel. The control of traffic light signal is one of the subjects of intelligent or advance systems being investigated by researchers because this kind of control has a direct impact on the effectiveness of urban transportation systems [1].
