摘要: 交通流微观仿真模型是目前广泛开展的智能运输系统项目开发、研究的重要内容。人们在研究、应用交通流微观仿真模型时,对模型验证过程重视不够。模型验证不足,使得模型本身不能达到其应有的精确程度,应用时常发生模拟结果与实际路况不能完全吻合的现象。结合一种基于投影寻踪回归的车辆跟驰模型,着重从微观角度,运用直观对比法和非参数统计方法对模型进行验证。验证结果表明,直观对比法和非参数统计方法用于模型验证是可行的。

Abstract: The microscopic traffic flow simulation models are important content in the study of intelligent transportation systems.The validation is not attracted attention enough in the study or application of microscopic traffic simulation models.The exactitude degree can not be achieved,because the models are short of validation.As a result,simulation results often can not match to the field ones when the models are used.In this paper,the straight comparison method and nonparametric statistical methods are used to validate the car-following model based on AHP in microcosmic level.The validation models are feasible through the test.

Key words: micro-simulation, driving behavior, car-following model, wald-wolfowitz runs method, run-length method
