【摘要】：高原公路是高原地區(qū)交通運(yùn)輸?shù)闹鲃?dòng)脈,是高原地區(qū)經(jīng)濟(jì)發(fā)展和社會(huì)生活的重要保障。高原公路多處于地質(zhì)復(fù)雜多變和生態(tài)環(huán)境較為脆弱的高山重丘地區(qū)；部分路段還會(huì)處于冰積地區(qū)。道路線形受高原地質(zhì)條件的影響表現(xiàn)出彎多、坡陡、高差大等特征,嚴(yán)重影響了駕駛舒適性、行車速度以及道路行車安全。在高原公路行車的駕駛員不僅會(huì)受到道路線形的影響,還要受到高原低氧、干燥、輻射等自然環(huán)境的干擾,有必要對(duì)高原公路線形的駕駛適宜性進(jìn)行研究。本文以人機(jī)工程學(xué)和交通心理學(xué)為理論基礎(chǔ),以高原公路曲線段和兩曲線間直線段的舒適性與安全性為研究對(duì)象,在G314線帕米爾高原路段選取典型路段進(jìn)行問卷調(diào)查、靜態(tài)檢測(cè)以及行車試驗(yàn)。通過對(duì)高原公路駕駛員進(jìn)行主觀心理問卷調(diào)查和靜態(tài)檢測(cè)得知,駕駛員心生理特性受高原低氧影響有明顯變化。為獲取駕駛員心生理特性變化與高原公路平曲線主要參數(shù)的直接關(guān)系,通過行車試驗(yàn)利用生物反饋設(shè)備對(duì)心率、血壓、肌電、腦電等駕駛員動(dòng)態(tài)心生理指標(biāo)進(jìn)行檢測(cè)；通過對(duì)各指標(biāo)高原變化特性的對(duì)比分析可知,心率能夠同時(shí)有效的反映出駕駛員緊張性和受低氧影響程度。為排除駕駛員個(gè)體差異的影響,即選用心率增長(zhǎng)率作為駕駛員緊張度的評(píng)價(jià)指標(biāo)。利用統(tǒng)計(jì)軟件SPSS對(duì)平曲線參數(shù)、高程、平均車速與心率增長(zhǎng)率進(jìn)行偏相關(guān)分析,排除了車速對(duì)心率變化的影響,分別建立平曲線半徑、高程與心率增長(zhǎng)率之間以及曲線間直線長(zhǎng)度、高程與心率增長(zhǎng)率之間的關(guān)系模型。結(jié)果表明,駕駛員在高原公路彎道或直線上行車時(shí),平曲線高程越高,半徑越小,駕駛員緊張度增加越明顯；兩曲線間直線長(zhǎng)度越小,高程越高,緊張度增加越明顯,駕駛員行車安全受到的影響越大。
[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.
