Based on the NS model of traffic flow, we propose a new single-lane cellular automaton model to study the effect of deceleration strips upon traffic flow.

本文在NS模型基础上建立了一个新的单车道元胞自动机模型以研究减速带对交通流的影响。

The consequent agreement in the behavior of the asymptotic steady state of the "corrective NS model" and FI model was discussed and the importance of random delay style was considered.

讨论了“修正NS模型”的渐进稳态行为与n模型的结果一致性，及考虑随机延迟方式的重要性。

Several faults in the improved NS model using two examples is pointed out and also another single lane traffic CA model by introducing vehicle_moving_status variable and feedback rule is proposed.

通过两种情况列出了改进的NS模型存在不尽周严的地方，随之在新模型中引入了行车状态变量和反馈规则，从而控制车辆出现倒车和刹车过急等现象。
