Abstract
With the advent and applications of sensor networks, pervasive traffic information can be gathered rapidly and collaboratively, which can upgrade traditional traffic monitoring system and enable many unprecedented services for travelers. In this paper, three-tiered sensor network architecture is proposed to approach the novel traffic information service system that would dramatically improve the ways and qualities of traffic information collection. A brief analysis of the important requirements of system, as well as the key issues that are faced in the design process, is described. The detailed strategies at each level, from the network architecture, to the sensor unit configuration and software deployment, to the operation of system, are explained. The implementation of a pilot platform is discussed in the end.
