摘　　要：对公路的特点和设计评价手段进行了分析,提出了建立公路仿真系统,对设计方案和设计指标进行评价的思路.分析了公路仿真系统的特点,建立了基于Multi-Agent的仿真系统框架,将仿真主体划分为反应Agent,合作Agent,界面Agent3类,分析了各Agent的结构特征.建立了多刚体汽车动力学模型、基于约束Delaunay三角网的公路视景模型、基于预瞄理论的驾驶员模型,并对仿真结果进行了初步的实验验证.By analyzing the character of highway and methods of highway design evaluation, the idea of building highway simulation system to evaluate highway design is put forward. The multi-agent framework of simulation system is built according to the characters of system. Further more, the simulation agents are divided into response agent, corporation agent and interface agent and their structures are analyzed. The vehicle model based on multi-rigid body, highway scene model based on constraint delaunay triangle net and driver model based on preview follower are built. The simulation results are validated by basic experiments. The simulation system is an efficient tools for highway design evaluation.
