2、g , T Shiliang Abstract 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
3、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 efficien
4、cy of the road network. Some extended applications of the proposed WSN system are discussed as well. 1. Introduction Transportation plays an important role in our modern society. How to efficiently exploit the transportation capacity of the existing transportation infrastructure receives a lot of at
5、tention from the researchers across the world. The Intelligent Transportation System (ITS) has been proposed by many researchers to solve the problem. ITS comprises of three main sub-systems. They are surveillance sub-system, analysis and strategy subsystem and execution sub-system. The execution su
6、bsystem can be a traffic control sub-system, a vehicle guiding sub-system, or a navigation sub-system. The surveillance sub-system measures the traffic information such as the vehicles location, speed, number of the vehicles on the road, etc., using certain type of sensor, such as inductive loops 1 or ultrasonic sensor 2. A new method based on video analysis is now under development 1;3. The analysis and strategy sub-system optimizes the traffic flows based on the measurements from
