An intelligent guiding and controlling system for transportation network based on wireless sensor network technology

This paper proposes architecture based on wireless sensor network (WSN) technology for intelligent transportation system (ITS) of a transportation network. With the help of WSN technology, the traffic info of the network can be accurately measured in real time. Based on this architecture, an optimization algorithm is proposed to minimize the average travel time for the vehicles in the network. Compared to randomly-chosen algorithm, simulation results show that the average speed of the road network is significantly improved by our algorithm, and thus improve the efficiency of the road network. Some extended applications of the proposed WSN system are discussed as well.
