【摘要】 在人、车、路的交通体系研究中,从医学和工学相结合的角度,以行车实验为依据,通过驾驶员的心率和血压的变动规律,用定量分析的方法研究道路线形构造同驾驶员心理压力和生理负担间的相关性,并建立定量的评价指标.以山区公路圆曲线线形构造要素的合理性和宜人性为研究对象,通过分析曲线半径与驾驶员心率血压变动的相关性,论证了最小曲线半径的合理性.更多还原

【Abstract】 This paper presents us a new view integrating medicine with engineering to study the traffic system consisting of human being,vehicle and road.As tokens of drivers’psychological and physiological pressure, heart rate and systolic blood pressure are got in many driving experiments,and their quantitative relationships with road alignment are also analyzed and established.The rationalization and comfort of curve in mountainous highways are the focuses of the paper; the reasonable value of the minimum curvature radius is suggested through analyying the relationship between the variation of drivers’heart rate and systolic blood pressure and the curvature radius.更多还原
