Abstract: Driving vehicles on the road probably change route according to road situation, which causes some difficulty to research of ATIS（Advanced Traveler Information System）. Traveler’s route choice and changing on road behaviors are studied based on method of multi-agent modeling and simulation. Traveler’s route choice model is build under changing on road, and an example is simulated using Repast S. Effect of traveler’s changing on road under ATIS is concluded at last. The method gives theory support for reasonable disposition and effective using.

Key words: Advanced Traveler Information System（ATIS）, Repast S, change on road, route choice

摘要： 出行车辆在行驶途中会根据路况随时调整行驶路径，这给公共交通先进出行者系统（ATIS）的研究带来一定的困难。基于多Agent仿真建模方法对ATIS 条件下出行者的路径选择及在途调整行为进行了研究，构建了在途路径调整下的出行者路径选择模型，并利用Repast S仿真工具进行仿真分析，得出了ATIS对出行者在途影响的结论。该方法为ATIS的合理配置和有效利用提供了理论依据。
