摘要:在计算机上进行交通仿真是帮助设计、分析和评估各类交通工程、管理和规划项目可选方案的有力工具。与西方发达国家一样,中国日益严重的交通拥堵问题促动了对应用和开发交通仿真软件的浓厚兴趣。阐述了中国开发和应用交通仿真软件的观点,认为当务之急是收集数据,客观地评价和分析现有各种交通仿真模型软件在不同条件下的适用性,对有关软件产品估计出适合中国人驾驶行为和环境条件的模型参数,提出应用指南,并对中国混合车流条件下,跟车、换道、插车和交叉口延误描述等驱动交通仿真软件的数学模型进行深入研究。

Abstract: Traffic simulation can be an effective tool in help-ing design and evaluation of alternative in various traffic engi-neering, management and transportation planning projects. In light of the growing interest in application and development of traffic simulation models and software in China, the author ar-gued that it is important to calibrate these models using ob-served local traffic data and drive behavior. We need to learn from the experience of other countries and avoid their mis-takes; we need basic research on traffic models such as car-fol-lowing, lane changing, gap acceptance, delay at signalized or unsigned intersections and so on under mixed traffic condition.
