Abstract:
Based on the variable security gap sensitive drivingmodel, a cellular automaton model describing the tollbooth on the road isproposed. Compared with NS tollbooth model, when stochastic probability ofbraking is large (p=0.5), the present model not only makes the capacity ofroad to be fully restored, but also makes it improve to a certain extent.When the value of the length of lane expansion L_{\rm B}is no less than 7, the capacity of road recovers well; while thecapacity of road will decrease.
