Implementation of ITS at Signalized Traffic Intersections and Operation Methods of Light Signalization with the Aim of Coordination
The basic mission of traffic signalisation is to inform the traffic participants about the characteristics of the road they are moving along, and to give command about the method of moving and other obligations they have to comply with. Their characteristic is the uniformity and recognisability everywhere in the world. In setting traffic signalization the designers have to take into account many factors before the traffic signs becomes the traffic regulator. The traffic sign can hardly bear the load of intersection regulation. For this purpose traffic lights are used. Traffic lights are electronic devices that control and regulate the traffic at intersections thus dictating the throughput and capacity of vehicles on sections of intersections. Designing of traffic signalization at intersections is a very demanding and responsible task which includes the activities of experts of several different profiles, first of all the traffic, construction as well as electrical engineering profile. It is generally known that the traffic light design procedure at intersections consists of several phases, and fuzzification represents one of the starting ones, and the quality of its implementation affects the quality, i.e. efficiency and efficacy of the overall system to be designed.
