Paper Details

The convergence of telecommunication, computing, wireless, andtransportation technologies facilitates that our roads and highways can be both ourcommunications and transportation platforms. These changes will completely revolution whenand how access services, communicate, commute, entertain, and navigate, in the comingfuture. Vehicular ad hoc networks (VANETs) are wireless communication networks that donot require any fixed infrastructure, and support cooperative driving among communicatingcars on the road. Vehicles act as communication nodes and relays, forming dynamic vehicularnetworks together with other near-by vehicles on the road and highways.This research paperexamines the possibility of deploying an priority based traffic signal control system inintersections, a system that can base its control decision on information coming from cars.Thus, each intersection with traffic lights is provided with a wireless infrastructure node thatcan extract data from an existing VANET. Now, efforts have been made to create traffic lightssystems that can respond to the ever increasing traffic. Most of the signal control systems relyon timing plans generated offline by traffic engineers using optimization models. Thesesystems are hard to maintain and do not respond well to traffic events, like a football game orroad construction,arrival of emergency vehicle. This research paper is focus on Priority basedtraffic signal control in VANET. Priority based means change according to arrival ofemergency vehicle. So in priority based traffic signal control is give green signal to lane as perthe current fixed cycle strategy. For making Priority base first find emergency vehicle on roadusing loop detector. So after each 60 seconds decision for green is taken based upon vehicletype over lanes. Green signal given to the lane(road) which have emergency vehicle at trafficsignal. It may possible that more than one of lane having emergency vehicle at traffic signal.Then as per arrival time of emergency vehicle we give green signal.
