We study analytically the occurrence of car accidents in the Nagel-Schreckenberg traffic model. We obtain exact results for the occurrence of car accidents P(ac) as a function of the car density rho and the degree of stochastic braking p(1) in the case of speed limit v(max)=1. Various quantities are calculated analytically. The nontrivial limit p(1)-->0 is discussed.
我们对纳格尔 - 施雷肯贝格交通模型中汽车事故的发生情况进行了分析研究。在速度限制(v_{max}=1)的情况下，我们得到了汽车事故发生率(P(ac))作为汽车密度(\rho)和随机制动程度(p(1))的函数的精确结果。通过分析计算了各种量。讨论了非平凡极限(p(1)\to0)的情况。
