【摘要】 本文首先对近年来通信领域的新技术无线传感器网络(WSN)以及传输协议(ZigBee)进行了简介,指出了将这些技术运用于智能公交领域的可行性。作者又分析了基于公交优先的交叉口信号控制方法的信息需求,在比较了现有检测与传输技术的优缺点之后,提出了用 WSN 与 ZigBee 技术实现交叉口公交优先信号控制,并给出了系统结构与运行过程。更多还原

【Abstract】 This paper at first briefly introduced the new telecommunication tech- nologies WSN and ZigBee,pointed out the possibility of their use in APTS field. The author analyzed the information demand of traffic signal control strategy based on bus priority.After comparing the advantages and disadvantages of pres- ent detecting technologies,the essay putted forward the idea to realize the cross- ing bus priority by using WSN and ZigBee,then provided the system structure, the operational process.更多还原
