实时信息的理论研究及应用

Research on theory of real-time information and application

针对实时信息服务的信息采集与处理问题,提出了实时信息的形式化定义与理论基础,建立了以实时信息采集与共享为基本功能的实时信息系统模型。该模型通过对实时信息系统的架构分析,确定了实时信息的采集和处理流程。在重点分析实时信息采集的完整性和精确性问题、实时信息场景重构问题的基础上,提出了实时信息的采集与处理机制。最后通过实例表明了基于实时信息的交通路径选择方法的性能。

Aiming at the problems of information collection and processing for real-time information services, the formal definition and theoretical foundation of real-time information are presented. Real-time information system model, which took real-time information collection and sharing as basic functions, is constructed. By analyzing the architecture of real-time information system, the real-time information collection and processing procedures are defined. Based on the analysis of the completeness and accuracy ofinformation collection issues and the scene reconstruction problem, real-time information collection and processing mechanism is proposed. Finally, performances of real-time information-based traffic path selection method are demonstrated by the application.
