Fuzzy Logic Timing Control for Standard Crossroad Lights

Fuzzy logic can be arranged concerning practical experiences and blended with conventional control techniques. Even though it is not the replacement of conventional control methods in many cases, a fuzzy control system eases the implementation and design process. It has also been put in use in other matters like traffic control. Increasing vehicles and insufficiency of passages capacity have led to widespread traffic emergence. While it is very difficult to widen existing roads, optimizing traffic like control schemas is still possible. This paper assumes a common four-directional crossroad where vehicles can move in a bidirectional way from each direction. A Sugeno fuzzy logic set of rules is presented to regulate the timing schedule of green lights for the crossroad concerning the vehicle accumulation at each line.
