【摘要】 高速公路交通量的增加对高速公路交通控制提出了更高的要求。传统的基于精确数学模型的交通控制方法很复杂并且在实际应用中往往达不到预期的控制效果 ,因此寻求新的有效的交通控制方法也就成为必然。多智能主体 (Multi- Agent)技术是人工智能领域中的一个研究热点 ,单个Agent能够自主地、主动地对对象进行控制 ,并且 Agent之间可以进行协作从而使整个系统达到更大的智能性。介绍多智能主体系统 (Multi- Agent System,MAS)的概念 ,然后描述基于 MAS的高速公路交通控制系统结构以及 Agent的内部模块的功能 ,最后对 Agent之间的协作进行了简要的分析。基于多智能主体的高速公路交通控制系统拥有一种全新的智能交通控制结构 ,它能够较好地克服传统交通控制系统所存在的缺陷 ,适应高速公路交通系统的复杂性和随机性。 MAS技术的关键在 Agent之间的协调 ,因此下一步的研究应该集中在 Agent之间如何建立有效的协调机制更多还原

【Abstract】 The increasing of expressway traffic quantity has brought forward a higher request on expressway traffic control. The traditional traffic control methods based on precise mathematics models is complex and the effects of their application always can not reach the expectation, so developing a new control method is necessary. Multi-agent technology is a hotspot in the artificial intelligence field. One agent controls its object autonomically and initiatively. Between two agents there is a cooperation which can improve the intelligence of the whole system. This paper introduced the concept of the Multi-Agent System(MAS), and described the architecture of the expressway traffic control system based on multi-agent and the functions of modules inside agent. A brief analysis of the cooperation between agents was presented. The expressway traffic control system based on multi-agent technology, which is an intelligent traffic control system with new architecture, can overcome drawbacks of the traditional traffic control methods and can adapt well to the complexity and randomicity of expressway traffic. The key of MAS technology is the cooperation between agents. Consequently the next research should be focused on how to build an effective mechanism of cooperation between agents.2 figs,8 refs.更多还原
