【摘要】 高速公路交通管理系统是为了缓解高速公路特别是城市高速公路交通拥挤、提高道路的有效利用率和交通流量、减少交通事故的发生率以及因交通事故造成的出行时间和经济等方面的损失、保护道路交通环境而建立起来的现代化的管理、控制系统。其以交通法规为原则,以计算机、信息网络等现代技术为手段,以运筹学、控制论为核心理论,以创造有序、迅速、安全舒适的行车环境为系统目标来对交通流合理引导、限制和优化。论文综合考虑高速公路交通管理系统的上述特征,分别从系统目标定位及概念设计、系统需求分析、系统数据管理及网络结构分析、交通控制与交通事件检测理论与应用四个层面,对高速公路交通管理与控制问题进行了系统阐述,界定了系统的功能及各功能的实现要求,并从系统集成角度划分了系统的结构;分析了各子系统的信息、功能、建设等方面的需求,给出了基本实施方案要求;对系统数据流程进行了描述和梳理,提出了数据管理的方法、目标及措施,分析、设计了系统网络拓扑结构及设备需求;阐述了交通模型的建模思想和动态交通模型的建立过程,对集中式和分散式全局交通控制理论进行了详细的分析,提出了基于预测的高速公路匝道控制理论,并对理论模式及相关的问题进行了研究,分析了高速公路事件检测系统,并采用面向对象的编程思想,以Visual C++为编写工具,开发了高速公路事件检测系统分析软件。

【Abstract】 Freeway traffic management system is modern management and control one which can relax traffic congest, improve road utilization, increase traffic flow, decrease traffic accident rate and economic loss, protect environment. It selects highway code as principle, operational research, and cybernetics as kernel theories in order to create well-ordered, speedy, safety-comfort travelling environment and realize traffic flow rational leading, limiting and optimizing. Synthetically considering these characteristics, the method of freeway management and control are presented according to four aspects: system objective orientation and concept design, system demand and requirement analysis, system data management and network structure, traffic control and accident detecting theory as well as its application. Function and structure of system are delimitated from the point view of integration. Construction and function demand of subsystem are analyzed and basic implement projects are presented. In this thesis, system data flow and management method and target which based on system network topology structure and equipment demand are described. Traffic modeling ideology and the process of making dynamic model as well as accident detecting program are presented with centralized and distributed traffic control theory in detail, then freeway ramp control theory which based on predictive model and its theoretic pattern are explored. Finally, based on the object oriented programming, program of accident detecting and checking on freeway is developed by using visual C++ as tool.
