INTELLIGENT TRAFFIC LIGHT CONTROL USING WIRELESS SENSOR NETWORKS WITH PRIORITIZE EMERGENCY VEHICLES

Vehicular traffic is the major problems in the fast developing countries. Major increase in number of vehicles in cities leads to heavy traffic congestion. Most of the traffic signals are based on fixed time allot ments. Higher traffic density at one side requires longer green signal as compared to the less traffic density at another side. The major disadvantage of fixed allotments at signal may cause higher traffic congestion at peak hours. To avoid the disadvantag e of fixed time allotment, we proposed a new method to control traffic in an efficient manner. This method has make use of Wireless Sensor Networks (WSN) at the road side junction and assigns time period to glow the respective lights. Based on the traffic at the junctions the time slot also varies. The sensor placed at the junctions will continuously monitor the vehicles and generate messages to avoid congestions. We also proposed to give importance to the Emergency vehicles such as ambulance, fire and VIP vehicles by giving special numbers to them. This technology is mainly designed to avoid traffic congestion at junctions and gives more priority to the emergency vehicles. These techniques are dynamically adapted for both single and multiple intersections
