【摘要】：高原公路是高原地区交通运输的主动脉,是高原地区经济发展和社会生活的重要保障。高原公路多处于地质复杂多变和生态环境较为脆弱的高山重丘地区；部分路段还会处于冰积地区。道路线形受高原地质条件的影响表现出弯多、坡陡、高差大等特征,严重影响了驾驶舒适性、行车速度以及道路行车安全。在高原公路行车的驾驶员不仅会受到道路线形的影响,还要受到高原低氧、干燥、辐射等自然环境的干扰,有必要对高原公路线形的驾驶适宜性进行研究。本文以人机工程学和交通心理学为理论基础,以高原公路曲线段和两曲线间直线段的舒适性与安全性为研究对象,在G314线帕米尔高原路段选取典型路段进行问卷调查、静态检测以及行车试验。通过对高原公路驾驶员进行主观心理问卷调查和静态检测得知,驾驶员心生理特性受高原低氧影响有明显变化。为获取驾驶员心生理特性变化与高原公路平曲线主要参数的直接关系,通过行车试验利用生物反馈设备对心率、血压、肌电、脑电等驾驶员动态心生理指标进行检测；通过对各指标高原变化特性的对比分析可知,心率能够同时有效的反映出驾驶员紧张性和受低氧影响程度。为排除驾驶员个体差异的影响,即选用心率增长率作为驾驶员紧张度的评价指标。利用统计软件SPSS对平曲线参数、高程、平均车速与心率增长率进行偏相关分析,排除了车速对心率变化的影响,分别建立平曲线半径、高程与心率增长率之间以及曲线间直线长度、高程与心率增长率之间的关系模型。结果表明,驾驶员在高原公路弯道或直线上行车时,平曲线高程越高,半径越小,驾驶员紧张度增加越明显；两曲线间直线长度越小,高程越高,紧张度增加越明显,驾驶员行车安全受到的影响越大。
[Abstract]:Plateau highway is the aorta of plateau transportation, and it is an important guarantee of economic development and social life in plateau area. Most plateau highways are located in high mountains and heavy hills with complex geological conditions and fragile ecological environment, and some sections will also be located in ice deposits. The road alignment affected by the geological conditions of the plateau shows the characteristics of many bends steep slopes and great height difference which seriously affect driving comfort driving speed and road driving safety. Drivers driving on highland highways will not only be affected by road alignment, but also disturbed by the natural environment such as altitude hypoxia, drying, radiation, etc. It is necessary to study the driving suitability of plateau highway alignment. Based on the theory of ergonomics and traffic psychology, this paper takes the comfort and safety of the curve section and the straight section between the two curves as the research object, and selects the typical section of the Pamir plateau section of the G314 line to carry on the questionnaire survey. Static test and driving test. Through the subjective psychological survey and static test, it was found that the physiological characteristics of the driver's heart were obviously affected by altitude hypoxia. In order to obtain the direct relationship between the physiological characteristics of the driver's heart and the main parameters of the plateau highway level curve, the dynamic cardiac physiological indexes such as heart rate, blood pressure, electromyography and EEG were measured by using biofeedback equipment. Through the comparison and analysis of the characteristics of the plateau, it can be seen that the heart rate can reflect the driver's tension and the degree of hypoxic influence at the same time. In order to eliminate the influence of individual difference of driver, the rate of heart rate is chosen as the evaluation index of driver's tensity. Using SPSS to analyze the partial correlation between the parameters of flat curve, elevation, average speed and heart rate growth rate, the influence of speed on heart rate was excluded, and the radius of flat curve was established. The relationship model between elevation and heart rate growth rate, straight line length between curves, elevation and heart rate growth rate. The results show that the higher the elevation of the flat curve and the smaller the radius, the more obvious the driver's tension increases, the smaller the length of the straight line between the two curves, the higher the elevation, the more the tension increases, the higher the driver is driving on the bend or straight line of the plateau highway, the higher the horizontal curve is, the smaller the radius is. The more the driver's safety is affected.
