| 摘 要： | 基于可变安全间距敏感驾驶模型对道路收费站系统进行了模拟研究. 与采用NS模型的
收费站系统进行了比较, 发现在慢化概率较大时(p=0.5), 该模型不仅使道路的通行能力
得到完全恢复, 还使其得到一定程度的提高; 当道路扩张区域长度L_{\rm B} \ge
7时, 通行能力得到很好的恢复; 当L_{\rm B}<7时, 随着L_{\rm B}的减少, 通行能
力也随之降低.

| Abstract: | Based on the variable security gap sensitive driving model,a cellular automaton model describing the tollbooth on the road is proposed.Compared with NS tollbooth model,when stochastic probability of braking is large(p = 0.5),the present model not only makes the capacity of road to be fully restored,but also makes it improve to a certain extent.When the value of the length of lane expansion L_B is no less than 7,the capacity of road recovers well;while the capacity of road will decrease. |
