| 摘 要： | 根据汽车动力学原理计算车辆安全制动距离,利用泊松分布函数研究武汉市长江隧道路面的车辆间距分布及路面摩擦系数与交通事故率的相关性。研究结果表明,摩擦系数的提高首先缩短了车辆的安全制动距离,从而减小了事故高发区域和意外状态下交通事故发生率。

| Abstract: | The author calculated the safe stopping distance of vehicles according to kinetic principle of automobile,studied the vehicles spacing distribution of the road surface of Wuhan Yangtze River tunnel by using the Poisson distribution function,and studied the relativity between friction coefficient and traffic accident rate.The findings indicated that the increase of the friction coefficient firstly shorten the safe stopping distance of vehicles,resulting the decrease of the traffic accident rate in the frequent accident area and accidental state. |
