Bus Priority Control System Based on Wireless Sensor Network (WSN) and Zigbee

In this paper, based on the analysis of the shortcomings of traditional technologies, including location technology, communication technology, the advantages of Wireless Sensor Network (WSN) and Zigbee are given first. Then the data requirements of Bus Priority Control System (BPCS) are presented. In the BPCS, the WSN nodes are classified into three types, i.e. intersection node, roadside node and vehicle node. Also the system architecture and operation process are expounded briefly. Finally, through the simulation and application of the test platform, the practicability is proved and some useful conclusions are drawn.
