【摘要】：隨著我國(guó)公路事業(yè)的不斷發(fā)展，高速公路在客貨運(yùn)交通中的優(yōu)勢(shì)地位日漸突出，但因雨霧等惡劣天氣引發(fā)的高速公路交通事故也在不斷增加。據(jù)統(tǒng)計(jì)，我國(guó)因霧引發(fā)的交通事故占高速公路交通事故總量的15%～25%。大霧災(zāi)害不僅成為影響高速公路交通安全的公害、大害，而且成為影響公眾出行和社會(huì)秩序的重要制約因素。本文在2013年云南省交通運(yùn)輸廳重大科技攻關(guān)項(xiàng)目-《特定高原氣候與復(fù)雜道路條件耦合作用下高速公路行車危險(xiǎn)路段安全保障技術(shù)研究》資助下，從高速公路霧的致災(zāi)機(jī)理、高速公路霧區(qū)的交通事故類型及特征分析、霧區(qū)高速公路安全行車控制技術(shù)、高速公路霧的監(jiān)測(cè)識(shí)別及預(yù)警發(fā)布技術(shù)等方面開(kāi)展霧對(duì)高速公路行車的影響及對(duì)策研究。 本文主要針對(duì)高速公路大霧頻發(fā)路段，在充分借鑒國(guó)內(nèi)外相關(guān)研究的基礎(chǔ)上，對(duì)高速公路霧的特點(diǎn)、霧的致災(zāi)機(jī)理、霧的量化分級(jí)、以及高速公路霧區(qū)的事故類型和事故特征進(jìn)行了詳細(xì)的分析研究。在此基礎(chǔ)上，本文以能見(jiàn)度和交通流量指標(biāo)為主要控制指標(biāo)，建立了多霧路段的安全控速方法，并對(duì)霧區(qū)高速公路限速具體實(shí)施方法進(jìn)行相應(yīng)的分析研究。同時(shí)，本文對(duì)霧區(qū)監(jiān)測(cè)設(shè)備進(jìn)行了相應(yīng)的選型分析，建立了多霧路段氣象信息監(jiān)控系統(tǒng)和低能見(jiàn)度條件下交通誘導(dǎo)系統(tǒng)，，通過(guò)可變信息情報(bào)板、可變限速標(biāo)志、視線誘導(dǎo)、無(wú)線廣播等多源方式發(fā)布可能的車速控制和有效的交通組織方式等技術(shù)措施，實(shí)現(xiàn)多霧路段警情信息和誘導(dǎo)措施的聯(lián)動(dòng)發(fā)布。
[Abstract]:With the continuous development of highway industry in our country, the superiority of expressway in passenger and freight transportation is becoming more and more prominent, but the traffic accidents caused by severe weather such as rain and fog are also increasing. According to statistics, The traffic accidents caused by fog in China account for 15% or 25% of the total number of highway traffic accidents. The fog disaster not only becomes a public hazard, but also a great harm to the highway traffic safety. In 2013, the major scientific and technological research project of Yunnan Provincial Transportation Department-< under the coupling of specific plateau climate and complex road conditions, the expressway driving danger'is also becoming an important restriction factor for public travel and social order. Study on Safety and Security Technology of dangerous sections of roads. According to the mechanism of highway fog, the types and characteristics of traffic accidents in the fog area of expressway, the safe driving control technology of expressway in fog area, The influence of fog on freeway driving and its countermeasures are studied in the aspects of monitoring and identification of expressway fog and the technology of warning and issuing. In this paper, the characteristics of fog, the mechanism of fog disaster, the quantitative classification of fog are discussed based on the study of heavy fog in expressway, based on the reference of related research at home and abroad. On the basis of the detailed analysis and study of the accident types and accident characteristics in the fog area of expressway, this paper takes the visibility and traffic flow index as the main control index, and establishes the safety speed control method of the multi-fog section. At the same time, this paper makes a corresponding analysis and analysis on the type selection of the monitoring equipment in the fog zone, and makes a corresponding analysis on the specific implementation method of the speed limit of the expressway in the fog zone. The meteorological information monitoring system of multi-fog section and the traffic guidance system under the condition of low visibility are established. The system is guided by variable information information board, variable speed limit sign and line of sight. Multiple sources, such as radio broadcasting, publish possible speed control and effective traffic organization, and realize the linkage release of police information and guidance measures in multi-fog road sections.
