摘　　要：微观交通仿真技术是解决城市交通网络拥塞问题的有效工具。在各种交通元素中,驾驶员-车辆单元是交通流的主体。该文通过对交通流中驾驶员、车辆特性的分析,将驾驶员和车辆视为一个整体,并基于Agent理论对之进行建模。文中详细分析了Agent的生成和路径搜索及选择算法,研究了Agent的跟驰、换道和挤占道等行为。该文最后介绍了基于Agent模型建立的一种微观交通仿真器,并在该仿真器上进行仿真实验。结果表明该系统能够较好的仿真实际交通流状况。The microscopic traffic simulation is an efficient means to resolve the traffic congestion in urban road network. Among the various traffic elements , driver and vehicle are the main bodies in traffic flow. By analyzing the characteristics of the drivers and vehicles in traffic flow, driver and vehicle are viewed as an integration and modeled based on Agent theory in this paper. The generation of driver - vehicle Agent, path search and choice algorithms are analyzed in detail; The Car - following, lane changing and the nosing behavior are also described in this paper. This driver- vehicle Agent model is applied to develop a microscopic traffic simulator,which is introduced in the last part of the paper. The simulations conducted on the simulator show the efficiency of the mechanism presented in this paper.
