摘要： 公路线形的构造直接影响行车安全,以山岭重丘区公路长大下坡的纵坡度值为研究对象,利用动态心电仪、GPS系统,对行车中驾驶员的心率和行车速度进行测试,研究了心率和行车速度的变动与纵坡度值的相关关系,分析了此种路段上纵坡度的合理值,建议在山岭重丘区公路线形设计中,不易出现大于5%的纵坡度值。

关键词: 交通工程, 线形设计, 心率, 速度, 纵坡度值

Abstract: The structure of the highway alignment has a direct effect on the driving safety.With the longitudinal gradient at the long slope alignment of the mountain highways as the research target,a study of the relationships between the driver's heart-rate,the vehicle speed and the longitudinal gradient of the long slope alignment is made to analyze the reasonable gradient at the long slope,by measuring the driver's heart-rate and the vehicle speed through the auto-recording heart-rate instrument and the motive GPS.On the basis of aboue research,the suggestion that the profile grade at the long slope alignment should not be more than 5% in the mountain highways is proposed.

Key words: traffic engineering, alignment design, heart-rate, vehicle speed, longitudinal gradient
