中文摘要：

采用摩擦接触理论和有限元方法分别计算了路面不同结冰工况下的汽车制动距离，并进行现场制动试验验证。结果分析表明，采取防冰措施可大幅降低制动距离和提高行车安全性，建议冰雪天气控制行车速度不超过60km／h，小汽车和货车的车辆间距分别不低于80m和100m，且宜采取间断放行方式以策安全。

英文摘要：

Frictional contact theory and finite element method were applied to calculate the braking distance under different freezing conditions. Calculation and field braking test results show that the anti-icing measures can significantly reduce the braking distance and improve the safety of driving. It suggested that driving speed should be less than 60 km/h on snow weather. The vehicle spacing of cars and trucks are less than 80 m and 100 m, respectively, and should carry traffic discontinuity to ensure safety.
