【摘要】：隨著我國經(jīng)濟(jì)的快速發(fā)展,高速公路建設(shè)事業(yè)也蓬勃發(fā)展,尤其在我國西部地區(qū),隧道越來越多,有些路段因地理?xiàng)l件特殊而形成隧道群路段,然而我國高速公路隧道群段交通事故數(shù)居高不下,尤其是出入口段,不僅事故率高,且嚴(yán)重性強(qiáng),如何合理的組織隧道出入口交通運(yùn)行,保證交通安全已成為交通工程部門著重進(jìn)行研究的重大課題之一。因此,進(jìn)行高速公路隧道出入口路段交通安全評價,甄別安全隱患,采取安全改善措施和保障技術(shù),對提高隧道出入口安全水平有著重大的意義。本論文依托國家自然科學(xué)基金青年基金項(xiàng)目“高速公路長大隧道群段駕駛員視覺疲勞致因機(jī)理與改善建議”,收集了典型山區(qū)高速公路長大隧道出入口的交通事故統(tǒng)計數(shù)據(jù),圍繞交通安全相關(guān)核心問題,運(yùn)用統(tǒng)計理論對數(shù)據(jù)進(jìn)行分析,明確了隧道出入口事故特點(diǎn),揭示了出入口安全的影響因素,建立了出入口安全評價模型,針對影響因子較高的因素提出了相應(yīng)的改善措施和安全保障技術(shù),進(jìn)行了以下主要研究:(1)通過連接段長度明確隧道群的概念,開展隧道出入口事故數(shù)據(jù)的調(diào)查研究,通過對數(shù)據(jù)資料收集、整理和統(tǒng)計分析,得出高速公路隧道出入口交通事故的時空分布特征,事故的形態(tài)和嚴(yán)重程度。(2)揭示隧道出入口事故致因機(jī)理,從駕駛員、道路、環(huán)境等不同的交通要素詳細(xì)分析了事故的影響因素,建立次序logit模型獲取影響因素的影響因子,通過比較獲得影響程度大的因素,分析這些因素的機(jī)理,提出保障行車安全的措施和技術(shù)。(3)基于傳統(tǒng)的層次分析法構(gòu)造判斷矩陣過程中存在的不足,運(yùn)用模糊數(shù)學(xué)中隸屬函數(shù)概念,創(chuàng)造性的提出了正態(tài)隸屬函數(shù)來構(gòu)建判斷矩陣,通過構(gòu)建安全評價層次結(jié)構(gòu),建立了隧道出入口安全評價模型,得到了安全系數(shù)的正態(tài)隸屬函數(shù),結(jié)合實(shí)例證明了模型的可靠性。(4)提出隧道出入口道路線形設(shè)計、減光格柵設(shè)置、GPS語音提示系統(tǒng)等措施改善隧道群出入口行車安全。
[Abstract]:With the rapid development of China's economy, highway construction is booming, especially in the western region of China, there are more and more tunnels. However, the number of traffic accidents in the highway tunnel group section is high, especially in the entrance and exit section, not only the accident rate is high, but also the severity is strong, how to organize the traffic operation of the tunnel entrance and exit reasonably. To ensure traffic safety has become one of the most important topics that traffic engineering departments focus on. Therefore, the highway tunnel entrance and exit sections of traffic safety evaluation, screening safety hidden dangers, safety improvement measures and security technology, It is of great significance to improve the safety level of tunnel entrance and exit. Based on the project of National Natural Science Foundation for Youth, "the Mechanism and suggestions for improvement of drivers' Visual fatigue in long Tunnel Section of Expressway", this paper has collected. Statistical data of traffic accidents at the entrance and exit of long tunnel in typical mountainous area, Based on the related core problems of traffic safety, this paper analyzes the data by using statistical theory, clarifies the characteristics of tunnel entrance and exit accidents, reveals the factors influencing the safety of the entrance and exit, and establishes the evaluation model of the safety of the entrance and exit. This paper puts forward the corresponding improvement measures and safety protection technology in view of the factors with higher influence factors, and carries out the following main research: 1. Through defining the concept of tunnel group in connection section length, the investigation and study of tunnel entrance and exit accident data are carried out. Through collecting, sorting and statistical analysis of the data, we can get the temporal and spatial distribution characteristics, the form and severity of the traffic accident at the entrance and exit of the expressway tunnel) and reveal the cause mechanism of the accident at the entrance and exit of the tunnel, from the driver, the road, Different traffic factors such as environment are analyzed in detail, order logit model is established to obtain the influencing factors, and the mechanism of these factors is analyzed by comparing the influential factors. Based on the shortcomings of the traditional AHP in the process of constructing the judgment matrix, this paper creatively puts forward the normal membership function to construct the judgment matrix by using the concept of membership function in fuzzy mathematics. By constructing the safety evaluation hierarchy, the tunnel entrance safety evaluation model is established, the normal membership function of the safety factor is obtained, and the reliability of the model is proved by an example. Some measures, such as GPS voice prompt system and so on, are used to improve the traffic safety at the entrance and exit of the tunnel group.
