Traffic Congestion Alert System using WSN (wireless sensor network)

Abstract

Traffic congestion is one of the major problem in now a days as cities are transforming into smart city this problem should be avoided. In the recent past, traffic congestion has emerged as one of the main challenge for engineers, planners and policy makers in urban areas. To overcome these problems, a system has to be designed which will able to alert for congestion and navigate for alternate path. “Traffic Congestion Alert System using WSN (wireless sensor network)” The suggested system detects the congestion on junction by IR sensors which are mounted on roads sided to monitor the traffic condition within a particular distance of meter. In each junction a transmitter and receiver will be present along with a LCD screen for display of message for congestion ahead. When congestion is reported an interrupt is sent to the controller by the array IR sensors and, CONGESTION AHEAD message is  sent to the neighboring junctions and a unique blinking of traffic light takes place which help in making decision for two wheeler or four wheeler either to change the route . Thus the rider has alerted for the congestion condition in advance. This facilitates to the rider in taking an alternate route in congestion free, avoiding being stuck in the traffic jam. After the particular junction gets clears, the traffic lights continues its control as normal. This helps in diverting the traffic on other route and hence reducing congestion.
