From this study, we found that most microscopic simulation models, such as VISSIM, use traditional car-followingtheory, which does not automatically exhibit the two-capacity phenomenon.
本文发现大多数微观模拟模型，例如VISSIM，尽管使用了传统的跟弛理论，但不能自动展示双能力现象。

On the basis of the classic car-followingtheory, under the ideal conditions, a headway model is put up in the paper.
基于经典的跟驰理论，建立理想条件下车辆稳定跟驰行驶时的车头间距模型。

The theory of optimization and car-following are adopted to determine the relationship between traveling speed and headway in this dissertation, and a model about critical speed is made.
