Intelligent transportation systems for wireless sensor networks based on ZigBee

Combining with the characteristics of intelligent transportation system and introduces wireless sensor networks technology. This paper illustrates a kind of intelligent transportation system solution of wireless sensor networks based on ZigBee technology. Through the comprehensive analysis of three respects of network topology, energy saving as well as being stable and reliable, this paper brings forward the hardware design of sensor network node and network protocols suitable for urban public transport system. Online travel buses can be monitored in real-time, to achieve the purpose of intelligent management. This system has higher cost performance compare with the current GPS used in public transit system.
