动态交通信息处理技术研究

Study on Data Processing Techniques of Dynamic Traffic Information

信息是智能交通系统的关键,ITS的各种功能都是以信息应用为中心展开的。交通信息处理系统是ITS各子系统联系的纽带和中枢,为ITS提供信息保障。阐述了交通信息处理系统的重要性和基本功能,对国内外交通信息处理技术进行了分析比较。在此基础上给出了系统框架流程设计,并对交通数据质量控制、信息融合、交通数据集成和存储等信息处理的关键技术进行了探讨。

Traffic information is the key of ITS and the traffic data processing system is the primary link of the rest subsystems of the ITS. In this paper, the basic function and particularity of real time traffic information collection and processing subsystem was given at first, and the technologies and key architecture of present ITS real time data processing system were reviewed and compared. Then, main parts of this subsystem traffic data quality control and traffic data archiving and storing were analyzed and designed.
