道路交通动态信息采集系统既是ITS的重要组成部分,又是ITS其它应用系统建设的基础.从系统构成、系统输入输出、系统功能单元、系统信息流程等方面对道路交通动态信息采集系统框架进行了总体设计;针对多种动态交通信息采集系统共存的现象,进行了应用框架设计;并以广州市为例设计了道路交通动态信息采集系统. The dynamic information collection system of road traffic is not only an important part of ITS but also the foundation of other ITS application systems.From the aspects of system configuration, system input and output, system function unit and system information flow, the dynamic information collection system framework of road traffic Overall design; Aiming at the coexistence phenomenon of many kinds of dynamic traffic information acquisition system, the application frame is designed; and the dynamic traffic information collection system of Guangzhou is designed as an example.
