摘　　要：事件自动检测系统是高速公路交通管理的基本组成部分,对高速公路的交通管理具有重要的意义。现代高速公路事件管理中,在发现、判断事件发生时,要求时间短,反应快,在短的时间和短的距离里获得大量的数据,要求数据具有实时性。为了满足事件检测的实时性,提高事件检测的效率,本文研究了实时数据库技术在高速公路事件管理中的应用,并设计了事件检测的AID系统和事件管理的实时数据库的分布式系统,该系统采用每个节点数据重复设置技术和PC and Sun workstation结构,能够满足高速公路事件的动态管理。Incident detection system is the base constitutes of freeway traffic management, it is very important for freeway traffic management. At present freeway traffic management, it should be short time and quick response for detecting and judging the incident, and get abundant real-time data at short time and short distance. In order to meet the real time of the incident detection and improve the efficiency, the real-time database was studied for the freeway traffic management application, the AID system and the distributed real-time database system were also designed. In this system, the key technology of replication of every data table and the structure of PC and Sun workstation were introduced. It can meet the dynamic traffic management for the freeway.
