摘　　要：为了找出冰雪条件下高速公路通行能力衰减规律,用理论计算和软件仿真相结合的方法得出高速公路通行能力衰减数据。结果表明,计算与仿真结论基本一致,不同路面状况下,低速时通行能力差异较小,高速时通行能力随附着系数减小而衰减明显。相同路面状况下,高速公路通行能力随车速增加而增大,达到最大通行能力后逐渐减小。In order to find out the rule of traffic capability attenuation of highway in snow and ice condition, the attenuation data was got based on theory calculation and software simulation. Result shows that the conclusion got from both the calculation and simula- tion methods are almost the same. In different pavement conditions, the difference of traffic capability is relatively small with low speed. But in high speed, the traffic capability is obviously attenuated with the decrease of adhesion coefficient. When the road con- dition is the same, highway capability first increases with the car speed, and then gradually decreases after arrived maximum traffic capability.
