The experiment verified the correctness of RSSI examination's the performance indicators and the parameter indicators in the actual environment application.The paper carried out the research of ZigBee wireless communication method and analyzes the ZigBee protocol stack's architecture.Above this foundation,the basic research of intelligent transportation using wireless sensor networks is carried on,which include the access of the traffic state information,data transmission,vehicles wireless localization and so on. Simulation experiments of a wireless location-related vehicle have been done under school campus's environment,parking area environment,and so on.The experiments realized the accurate localization of vehicles within the coverage area of reference node, and have made the relevant data analysis.The paper makes an adequate experiment in order to verify the function of the vehicles positioning system based on wireless sensor network using ZigBee,and carries on observation and analysis to network of ZigBee protocol stack and data exchange process.The wire sensor network which oriented towards the access to the traffic state information using field bus and Ethernet is contrasted and analyzed.
