【摘要】：自1988年我國第一條高速公路（滬嘉高速公路）開通運(yùn)營以來，我國高速公路的建設(shè)穩(wěn)步發(fā)展。24年間，已逐步建成了由7條首都放射線、9條南北縱線和18條東西橫線組成的“7918”高速公路結(jié)構(gòu)網(wǎng)。隨著我國高速公路的迅猛發(fā)展，高速公路的建設(shè)也逐步從平原地區(qū)轉(zhuǎn)向山區(qū)、由經(jīng)濟(jì)相對發(fā)達(dá)的地區(qū)轉(zhuǎn)向經(jīng)濟(jì)欠發(fā)達(dá)的地區(qū)。越來越多山區(qū)高速公路的開通運(yùn)營，對發(fā)展山區(qū)經(jīng)濟(jì)，改善山區(qū)人民生活起到至關(guān)重要的作用。但是，當(dāng)人們享受越來越便利的快速交通的同時也面臨著交通事故的影響,特別是路側(cè)事故，不管是發(fā)生的概率還是嚴(yán)重程度，一直不斷地呈增長趨勢。因此，迫切需要對山區(qū)高速公路路側(cè)安全的影響機(jī)理進(jìn)行細(xì)致的研究。 本文首先結(jié)合江西省交通廳重點(diǎn)科技項目《不利氣候條件下山區(qū)高速公路路側(cè)安全關(guān)鍵技術(shù)研究》，選取江西省三條典型山區(qū)高速公路為研究對象，分別從時間、天氣、車型和線型指標(biāo)四個方面鑒別了山區(qū)高速公路路側(cè)事故的內(nèi)部特征。 接著從主、客觀兩個方面探究了路側(cè)事故的影響機(jī)理。 主觀方面，主要從駕駛員在行車過程中的生理和心理條件著手。通過對駕駛員生理學(xué)機(jī)理的研究得出：⑴駕駛員因長時間處于靜態(tài)施力而導(dǎo)致肌肉疲勞和眩暈是影響路側(cè)事故的因素之一；⑵駕駛員兩側(cè)后方區(qū)域各有約17.75°的“視野盲區(qū)”，而這一“視野盲區(qū)”恰恰有可能影響路側(cè)事故。 客觀方面，首先針對雨天環(huán)境、冰雪環(huán)境和霧天環(huán)境下各自不同的屬性特征，采用基于停車視距的限速模型、車輛滑水臨界模型、雪天安全行車限速模型和ADAMS/Car軟件分析路面附著系數(shù)和大氣能見度對路側(cè)安全的影響。然后將重點(diǎn)集中在行車道以外的路側(cè)環(huán)境上，發(fā)現(xiàn)路側(cè)安全凈區(qū)寬度和邊坡坡度的取值，路肩的設(shè)置，邊溝的型式以及路側(cè)護(hù)欄的設(shè)置和型式選取都與路側(cè)安全息息相關(guān)。
[Abstract]:Since the opening and operation of the first expressway (Hu-Jia Expressway) in China in 1988, the construction of freeway in China has developed steadily in the past 24 years.The "7918" freeway structure network composed of 7 capital radiation lines, 9 north-south vertical lines and 18 east-west crosslines has been gradually built.With the rapid development of expressway in China, the construction of expressway has gradually changed from plain area to mountainous area, from economically relatively developed area to economically underdeveloped area.The opening and operation of more and more mountain highway plays an important role in developing mountain economy and improving people's life.However, when people enjoy more and more convenient rapid traffic, they are also faced with the impact of traffic accidents, especially roadside accidents, no matter the probability of occurrence or severity, has been continuously increasing trend.Therefore, it is urgent to study the influence mechanism of highway side safety in mountainous area.In this paper, based on the key scientific and technological project of Jiangxi Provincial Communications Department, "study on key Technologies of Highway side Safety in Mountain area under unfavorable Climate", three typical mountain highways in Jiangxi Province are selected as research objects, respectively from time and weather.The interior characteristics of highway side accidents in mountainous area are identified in four aspects: vehicle type and linear index.Then it explores the influence mechanism of road side accident from two aspects: subjective and objective.Subjective aspects, mainly from the driver in the driving process of the physical and psychological conditions.Through the study of the physiological mechanism of driver, it is concluded that muscle fatigue and vertigo caused by long time static force are one of the factors that affect the road side accident. 2. There are about 17.75 擄"blind area of visual field" in the rear area of driver on both sides of driver.And this "blind area of vision" is precisely likely to affect the side of the road accident.Objectively, first of all, according to the different attribute characteristics of rainy, snow and fog environments, the speed limit model based on parking horizon and the critical model of vehicle water skiing are adopted.The speed limit model and ADAMS/Car software are used to analyze the influence of road adhesion coefficient and atmospheric visibility on road side safety.Then the emphasis is placed on the roadside environment outside the carriageway, and it is found that the selection of the width of the safe clear area and slope slope, the setting of the kerb, the type of the side ditch, the setting of the roadside guardrail and the selection of the type are all closely related to the safety of the side of the road.
