中文摘要：

关键交通基础设施（critical transportation infrastructure,CTI）模型是社会仿真中国家关键基础设施（national critical infrastructure,NCI）仿真的重要组成部分。为寻求CTI这类复杂网络系统适用的建模与仿真方法,介绍了CTI的概念,分析了CTI的组成及特点,引入了Agent技术,提出了一种基于Agent的CTI模型。通过设计CTI中主要Agent的结构、属性、行为和交互,初步实现了模型的仿真运行,并给出了仿真结果。结果表明模型是合理和正确的。

英文摘要：

Critical transportation infrastructure （CTI） model is an important component of national critical infrastructure（NCI） simulation in virtual societies. In order to seek a method suit to model and simulate complex network system like CTI, the concept of CTI was introduced; the components and characteristics of CTI are analyzed. A new CTI model based on Agent is put forward after briefly introduced Agent technology. By designing the structure, attribute, behavior and interaction of major Agent classes in CTI, the simulation of the model is primarily realized and the simulation result is also presented. The simulation result shows that the Agent based CTI model is reasonable and right.
