Survey on Application of Wireless Sensor Networks for Traffic Monitoring

Wireless sensor networks are new integrative technologies arising from the development of wireless communication and tiny sensors. With the reduction of power consumption and cost of instruments and maintenances, it's ready to install over large-scale traffic areas and monitor roads in a much fine way, which is certain to bring some breakthroughs in the field of traffic monitoring. Surveying the technologies of vehicle detecting nodes, communication networks, traffic forecasting algorithms and architecture, this paper gives a full view of the application of wireless sensor networks in traffic monitoring systems. The key technologies and future development trends are also analyzed in details.
