摘　　要：以某公路长大下坡试验路段为例,在提出此类路段关键控制指标以及交通事故的发生原因后,构建小客车运行速度预测模型和货车制动毂温度预测模型,采用SPSS软件分析刹车轮毂温度的影响因素以及彼此间存在的影响机制,并预测长大下坡路段安全坡长的取值。经过本次研究,为该类特殊路段的设计工作提供参考,严格控制坡长及相关关键参数,提高长大下坡路段的设计水平,保障车辆行驶安全。This article takes a long downhill test section of a certain highway as an example.After proposing key control indicators and the causes of traffic accidents in such sections,a prediction model for passenger car operating speed and a prediction model for truck brake hub temperature are constructed.SPSS software is used to analyze the influencing factors of brake hub temperature and their influencing mechanisms,and to predict the value of safe slope length in long downhill sections.After this study,reference is provided for the design work of this type of special road section,strictly controlling the slope length and related key parameters,improving the design level of long and steep downhill sections,and ensuring vehicle driving safety.
