| 摘 要： | 为研究冰雪环境下的道路通行能力,首先分析道路通行能力理论公式,综合考虑冰雪环境下的车辆运行特点,选择前后车刹车距离相等情况下的通行能力模型做为计算模型,然后分析速度与车辆几何结构、车辆偏离中心距离及摩擦系数间的关系,建立速度预测模型,验证该模型的可行性,并在此基础上计算冰雪环境下的道路通行能力。

| Abstract: | To research the highway capacity under snow disaster,analyzed the formula of highway capacity and chose the capacity model under the circumstance of braking distance equality between front vehicle and rear vehicle after overall consideration,then analyze the relation between velocity and geometric construction,off-centered distance and friction coefficient,set up apredicting model of velocity,and validated the feasibility,at last,calculated the highway capacity under snow disaster. |
