摘要
视距是评价汽车行驶安全性和舒适性的重要指标.从医学和工学相结合的角度,以行车实验为依据,对驾驶员心率和血压变动规律与山区公路平曲线通视距离相关性进行分析研究.基于人机工程学实验研究表明,山区公路平曲线通视距离,应比现行理论计算通视距离增加5-10 m的安全距离,同时提出了相应的山区交通安全改善措施.
The driving sight distance is an important indicator for evaluating driving safety and comfort. This paper presents a new view integrating medicine with engineering to study the quantitative relationship between the drivers heart rate systolic blood pressure and driving sight distance at the small radius curve part of mountainous highways. Based on the ex- periment research of ergonomics, the reasonable value of driving sight distance should be five to ten meters longer than the calculated driving sight distance. Some countermeasures are also given to improve the traffic safety at the small radius curve part of mountainous highways.
