Traffic Lights Control using Wireless Sensors Networks

Optimization of signal control at intersection by using real time traffic collected by wireless sensor network presents an important focus of research into intelligent transportation system. Several studies have proposed adaptive algorithm road traffic, which concentrates on determining green light length and sequence of the phases for each cycle in accordance with the real time traffic detected, and in order to minimize the waiting time at the intersection, these methods have chosen to give priority to the largest queue. In this paper we propose adaptive traffic light control method for an isolated intersection that considers a number of traffic factors such as traffic volume, waiting time, etc. In this method we give priority to the shortest queue and we show that this method gives an optimal waiting time.
