THE AUTOMATED BRIDGE TRAFFIC CONTROL MECHANISM USING FUZZY LOGIC SYSTEM

Vehicular travel is increasing throughout the world, particularly in the urban areas. With the increasing use of automobiles in cities traffic congestion occurred. So there is requirement for optimizing traffic control methods to better accommodate the increasing demand, so as the transportation system will continue to grow intelligent Traffic Controls have to be employed to face road Traffic congestion problems. Fuzzy Controllers have been widely used in many consumer products and industrial applications with success over the past two decades for Traffic control, however, Fuzzy controllers have not been widely applied. This paper proposes a Fuzzy Traffic Lights Controller to be used at a complex Traffic junction. The real time parameters such as Traffic density and queue length are obtained by using image processing techniques. So, the on/off timings for the green, red and orange lights are adjusted as per the actual road conditions. Fuzzy Logic has been widely used to develop a Traffic signal Controller, because, it allows qualitative modeling of complex systems. This project describes a Fuzzy Logic controller for a four –way intersection suitable for mixed traffic, including a high proportion of motor vehicles. This project discusses the Traffic control strategy, which dictates the design criteria for the Fuzzy Logic Controller. The components of Fuzzy Logic Controller-the Fuzzifier, the Fuzzy rule base formulate by human experts, the Fuzzy interference engine and the defuzzifier.
