【摘要】 公路线形构造直接影响驾驶行为和行车安全。以山区公路平曲线通视距离的安全性为研究对象,利用全自动血压仪,对行车中驾驶员心率和血压的变动进行实验测试。定量分析的结果表明驾驶员的心率与收缩压同平曲线通视距离有很高的相关性,建议在低等级山区公路,平面线形设计应满足35m以上的通视距离。更多还原

【Abstract】 Alignment has direct effect on drivers’ behavior and driving safety.This paper aims at safe visible distance of mountainous highways,the variety of drivers’ heart rate and systolic blood pressure is measured during driving by use auto-recording blood pressure instrument.Quantitative analysis demonstrates that there has high relationship between visible distance and drivers’ heart rate and systolic pressure.A suggestion is put forward that visible distance should not be less than 35 meter in lower class mountainous highways.更多还原
