基于元胞自动机的刹车灯模型交通流分析

摘要

By changing the definition of“very good driving conditions”in Tian model and considering the impact of deceleration after acceleration to randomization in the model ,produced a new model of Tian.Through specific numerical analysis flow improved cellular automata greater than NS cellular automata ,and on the basis of the brake lights on the model by using the cellular automaton to simulate traffic flow is more realistic.%通过改变Tian模型中对“非常好的驾驶条件”的定义以及在模型中考虑车辆加速后再减速对随机慢化的影响，提出了新的Tian模型。通过具体的数值分析发现改进后的元胞自动机的流量要大于NS元胞自动机，且在刹车灯模型的基础上用元胞自动机模拟出的车流量更加符合实际的交通情况。
