We study the occurrence of car accidents in the Nagel-Schreckenberg model. Both the effects of stochastic braking and speed limit are analyzed. An approximate scaling relation is observed with the varying of speed limit. The stochastic noise will enhance the probability for accidents in the low density region and suppress that in the high density region. The probability for car accidents to occur becomes a broadened distribution over a wide range of density.
我们研究了纳格尔 - 施雷肯贝格模型中汽车事故的发生情况。分析了随机制动和速度限制的影响。观察到随着速度限制的变化存在一种近似的标度关系。随机噪声会增加低密度区域事故发生的概率，而在高密度区域则会抑制事故发生概率。在很宽的密度范围内，汽车事故发生的概率呈现出一种展宽的分布。
