While the traditional vehicles have apparently unable to meet the demand of the new car, urgently needed to support and development road system in urban traffic information, the application requirements, this article introduces the EASYARM1138 such chips and MC13213 + uC/OS - II operating system flat, we design and implement a ZigBee technology based on the wireless car path automatically stops system, This system has the advantages of small size, the function is strong, low power consumption, real-time and good stability etc, can significantly reduce the labor intensity, the driver staff effectively lower the error due to manual stops to wait for an accident happening, but as a city bus system of intelligent an integral part. To improve the urban traffic intelligent and informatization has important significance. 目录 摘要 I
