STUDY OF AUTOMATIC TRAFFIC SIGNAL SYSTEM FOR CHANDIGARH

The increasing number of vehicles on our road intersections has given rise to the problems like road accidents, congestions, conflicts and bottlenecks. These problems can now only be solved by providing an efficient traffic control at intersections and that can be achieved by provision of automated volume-based traffic signal system at intersections for continuous and efficient movement of vehicles through the intersections Chandigarh – the city beautiful – though a modern and well-planned city, is also facing the same traffic problems. Here, the present traffic signals are based on the static feed of time without considering the actual available traffic. This leads to a situation where vehicles wait unnecessarily in one of the lanes while the traffic flow is not up to the considerable amount in the other lane. This paper provides the feasibility of replacing existing traffic signals with a system to monitor the traffic flow automatically in traffic signals where sensors are fixed in which the time feed is made dynamic and automatic by processing the live detections. The paper deals with the feasibility of provision of inductive loop detection-based traffic signals in place of existing Pretimed traffic signals by comparing their performance, suitability and economics.
