【摘要】：本文在分析連續(xù)長下坡路段事故特征及原因的基礎(chǔ)上,首先對三種貨車制動(dòng)鼓溫升模型的特點(diǎn)和適用范圍等進(jìn)行了分析比較,最后選用無輔助制動(dòng)下的制動(dòng)鼓溫升模型作為事故預(yù)測的工具,建立了基于車輛制動(dòng)失效與道路縱坡關(guān)系的長下坡路段事故預(yù)測方法;與此同時(shí),本文還分析了常用的道路安全性評(píng)價(jià)方法,并參照《公路項(xiàng)目安全性評(píng)價(jià)指南》方法,建立了基于道路線形設(shè)計(jì)安全性評(píng)價(jià)的長下坡路段事故預(yù)測方法。兩種方法相互補(bǔ)充和驗(yàn)證,能夠有效提高事故預(yù)測的準(zhǔn)確性。在此基礎(chǔ)上,本文還結(jié)合連續(xù)長下坡路段的事故特點(diǎn)和安全保障要求,系統(tǒng)研究了連續(xù)長下坡路段的安全防治技術(shù),為連續(xù)長下坡路段的事故防治工作提供了理論指導(dǎo)與技術(shù)支持。結(jié)合兩種方法預(yù)測出的長下坡路段事故多發(fā)點(diǎn),考慮路段的實(shí)際情況,對于已建成公路的長下坡路段,主要考慮對事故多發(fā)點(diǎn)采取相應(yīng)的被動(dòng)防護(hù)措施,包括安全保障設(shè)施建設(shè)、緊急避險(xiǎn)車道設(shè)置等,使車輛在長下坡路段盡可能安全的行駛;對于新建或擬建公路的長下坡路段,由于缺乏事故資料,結(jié)合兩種方法預(yù)測出的長下坡路段事故多發(fā)點(diǎn),主要考慮采取相關(guān)的主動(dòng)防治措施,包括公路縱坡設(shè)計(jì)優(yōu)化、信息告知系統(tǒng)與緊急救援系統(tǒng)構(gòu)建、交通安全設(shè)施設(shè)計(jì)等,這樣可以有效預(yù)防事故的發(fā)生;對于不同類型及不同等級(jí)的公路長下坡路段,都應(yīng)該加強(qiáng)路段的安全管理,這主要包括安全宣傳與教育與路段限速標(biāo)準(zhǔn)的確定等。將管理措施與防治措施相結(jié)合可以有效的地預(yù)防長下坡路段交通事故的發(fā)生。通過本文的研究可以為如何預(yù)測連續(xù)長下坡路段的事故多發(fā)點(diǎn)提供依據(jù),結(jié)合研究出的基于車輛制動(dòng)失效的長下坡路段事故預(yù)測方法,分析以運(yùn)行速度為基礎(chǔ)的長下坡路段安全性評(píng)價(jià)方法及評(píng)價(jià)結(jié)果,對可能的事故多發(fā)點(diǎn)加強(qiáng)相應(yīng)防治措施的實(shí)施,對我國公路連續(xù)長下坡路段事故的防治具有實(shí)際指導(dǎo)意義。
[Abstract]:Based on the analysis of the accident characteristics and causes of the continuous long downhill section, this paper first analyzes and compares the characteristics and applicable scope of the three kinds of truck brake drum temperature rise models. Finally, the model of temperature rise of brake drum without auxiliary braking is chosen as the tool of accident prediction, and the method of predicting long downhill road accident based on the relationship between vehicle braking failure and road longitudinal slope is established, at the same time, This paper also analyzes the commonly used methods of road safety evaluation, and establishes a method of accident prediction for long downhill road sections based on safety evaluation of road line design, referring to the method of highway project safety evaluation. The two methods complement and verify each other, which can effectively improve the accuracy of accident prediction. On this basis, combined with the accident characteristics and safety requirements of the continuous long downhill section, the paper systematically studies the safety prevention and treatment technology of the continuous long downhill road section. It provides theoretical guidance and technical support for accident prevention and treatment of continuous long downhill sections. Considering the actual situation of the long downhill road section, considering the actual situation of the long downhill road section predicted by two methods, the corresponding passive protection measures are mainly considered for the long downhill section of the highway that has already been built. Including the construction of safety and security facilities and the setting of emergency safe havens, so that vehicles can drive safely in long downhill sections as far as possible. For long downhill sections of new or planned highways, due to the lack of accident data, Combined with the two methods to predict the accident prone points of long downhill road sections, the main consideration is to take relevant active prevention measures, including highway longitudinal slope design optimization, information notification system and emergency rescue system construction, traffic safety facilities design, etc. For different types and different grades of long downhill road sections, the safety management of road sections should be strengthened, which mainly includes safety propaganda and education and determination of speed limit standards of road sections and so on. The combination of management measures and prevention measures can effectively prevent traffic accidents in long downhill sections. The research in this paper can provide the basis for how to predict the accident prone points of continuous long downhill sections, combined with the study of the long downhill road accident prediction method based on vehicle brake failure. This paper analyzes the safety evaluation method and evaluation results of long downhill road sections based on running speed, strengthens the implementation of corresponding prevention measures for possible accident prone areas, and has practical guiding significance for the prevention and treatment of accidents in continuous downhill sections of highways in China.
