摘要
NETSIM凭借其对城市道路交通现象的高精度描述,能够真实再现动态交通的随机行为,已在世界范围内得到了广泛的应用。文章分析了NETSIM模型的现状及优缺点,对于车辆行驶中的跟车模型、车辆换道模型以及信号控制交叉口的延误模型配以相应的时空分布图并进行了详细地探讨,从中可以体会到该模型对车辆及驾驶员特性的精确描述。
NETSIM can precisely describe the urban traffic and truly replay the stochastic actions of the dynamic traffic. Therefore, it has been widely used all over the world. This paper mainly analyzes its status, advantages and disadvantages. Based on the time-space figure, this paper discusses the car-following model, lane-changing model and delay model of signal intersection in details, which shows its accurate description of the characteristics of vehicles and drivers.
