Abstract: Aiming at solving the key technical problems of urban traffic, the intelligent means and approach which combine artificial intelligent and tradition control are adopted. On the basis of introduction of Chinese urban traffic control system structure and function requirement, a kind of frame structure of urban traffic intelligent control system based on multi-agents cooperation is stated. According to the frame structure, a kind of real-time and effective system design idea oriented to urban traffic is established; the system design of urban cross control and area control based on multi-agents is implemented. In this way, the goal for urban traffic intelligent control is insured so as to increase the capacity of urban road network and improve our urban traffic control and management modes. Therefore urban surroundings quality will be enhanced, and the comfortable and delightful traffic surroundings will be built.

Key words: multi-agent, urban traffic, integrated control, intelligent transport system (ITS)

摘要： 针对我国城市交通迫切需要解决的关键技术问题，采取传统方法与人工智能相互结合的智能方法与步骤，在引出我国城市交通控制系统结构与功能要求的基础上，阐述一种基于多智能体（multi-agent，MA）协作的城市交通智能控制系统的框架结构。根据该系统框架结构，建立一种面向城市交通实时、有效的控制系统设计思想，完成了基于多智能体的城市路口控制、区域控制的系统智能控制设计，完善我国城市交通控制与管理模式，以确保城市交通智能化控制目标的顺利实现，提高路网通行能力，改善城市环境质量，营造出舒适宜人的交通环境。
