Fuzzy Coordination System for Traffic Light

The traffic light is a signaling device that helps to manage the traffic. The current system uses rigid value to control the traffic timing. However, due to its unresponsiveness to the current traffic condition, the traditional traffic light system sometimes could cause a traffic jam. This is due to improper setting of timing which didn’t consider the current situation i.e. heavy traffic during peak hour. Therefore, the use of human reasoning associated with the existing traffic control system is very important as it could react and change according to real-time condition. Fuzzy logic is able to do that as it is applying human logic and good at handling fuzziness in the world and produce the optimum output for the condition. Hence, this study identifies the traffic light timing setting problem and develops an intelligent traffic light system as a solution based on fuzzy logic. This web-based system is beneficial as a controller and monitoring for improving the traditional system. It is able to make changes to the green light duration according to the traffic condition at the current time of day e.g. peak, normal and off-peak as well as the density (congestion) of the road.
