【摘要】：隨著高速路網(wǎng)的逐步發(fā)展,公路運(yùn)營(yíng)中不斷暴露出道路使用壽命短、車流穩(wěn)定性差、交通事故頻發(fā)、路面破壞嚴(yán)重、道路通行能力不能有效利用等諸多問題;同時(shí),隨著國(guó)民經(jīng)濟(jì)能力提升,群眾的需求層次進(jìn)一步多樣化發(fā)展,特別是客貨運(yùn)的不同發(fā)展需求,迫切需要建設(shè)更專業(yè)化的道路系統(tǒng),達(dá)到需求與供給的質(zhì)量匹配和總量平衡�？拓浄志�能有效緩解傳統(tǒng)客貨混行帶來的困擾,國(guó)內(nèi)已有部分道路實(shí)施了客貨分線,其實(shí)際效益也逐步被認(rèn)可。但由于相關(guān)理論及行業(yè)規(guī)范的缺失,沒有詳實(shí)準(zhǔn)確完善的技術(shù)作為支撐,導(dǎo)致設(shè)計(jì)時(shí)仍采用客貨混行的技術(shù)指標(biāo),比較盲目隨意且不符合實(shí)際需要,故加快完善客貨分線相關(guān)理論,具有里程碑意義。論文通過分析國(guó)內(nèi)外客貨分離理論研究與實(shí)施狀況,確定了論文研究的基本方向,提出了客貨分線的概念,確定了專用車道代表車型,探討了客貨分線的優(yōu)勢(shì),并運(yùn)用層次析法和VISSM仿真對(duì)客貨分線的適用條件及車道功能劃分進(jìn)行了初步研究。文章重點(diǎn)研究了客貨分線幾何設(shè)計(jì)技術(shù)指標(biāo),根據(jù)客貨車型不同,應(yīng)用國(guó)內(nèi)外成熟理論和方法,分別計(jì)算研究客車專用道路與貨車專用道路的車道寬度、中間帶和同向帶寬度、縱坡主要參數(shù)值、立交型式及交通流組織措施。結(jié)合云南小鋪至烏龍高速公路共用段改擴(kuò)建工程項(xiàng)目,利用本文客貨分線研究成果,對(duì)其實(shí)施方案進(jìn)行重新比選,證明了實(shí)施客貨分線的可行性和必要性。文章分析了客貨分線的優(yōu)勢(shì),構(gòu)建了客車專用車道和貨車專用車道模型,并對(duì)其幾何設(shè)計(jì)中的部分重點(diǎn)指標(biāo)完成了理論計(jì)算,為客貨分線的發(fā)展奠定基礎(chǔ)。
[Abstract]:With the gradual development of highway network, many problems have been exposed in highway operation, such as short service life of road, poor stability of vehicle flow, frequent traffic accidents, serious damage of road surface, and the inability of effective utilization of road capacity. With the improvement of national economy capacity and the further diversification of the mass demand levels, especially the different development needs of passenger and freight transport, there is an urgent need to build a more specialized road system to achieve the quality matching between demand and supply and the balance of total quantity. Passenger and cargo sub-line can effectively alleviate the problems caused by traditional mixed passenger and cargo lines. In China, some roads have implemented passenger and cargo sub-lines, and their actual benefits have been gradually recognized. However, due to the lack of relevant theories and industry norms, there is no detailed, accurate and perfect technology as the support, which leads to the technical index of mixed passenger and freight lines still used in the design, which is blind and random and does not meet the actual needs. Therefore, speeding up the improvement of passenger and cargo sub-line related theory, has milestone significance. By analyzing the theoretical research and implementation of passenger and cargo separation at home and abroad, this paper determines the basic research direction of the paper, puts forward the concept of passenger and cargo separation, determines the representative type of special lane, and probes into the advantages of passenger and cargo separation. Using hierarchical analysis method and VISSM simulation, the applicable conditions and lane function division of passenger and cargo separation lines are studied preliminarily. This paper focuses on the technical index of geometric design of passenger and freight cars. According to the different types of passenger and freight cars, applying mature theories and methods at home and abroad, the width of carriageway, intermediate belt and codirectional zone of special road for passenger cars and freight cars are calculated, respectively. Main parameters of longitudinal slope, interchange type and traffic flow organization measures. Combined with the reconstruction and extension project of the common section of the Xiaopu to Wulong Expressway in Yunnan Province, the feasibility and necessity of carrying out the passenger and cargo sub-line are proved by using the research results of the passenger and freight sub-line in this paper. In this paper, the advantages of passenger and freight lines are analyzed, and the models of passenger and freight car lanes are constructed, and some important indexes in geometric design are calculated theoretically, which lays a foundation for the development of passenger and freight lines.
