【摘要】：随着高速路网的逐步发展,公路运营中不断暴露出道路使用寿命短、车流稳定性差、交通事故频发、路面破坏严重、道路通行能力不能有效利用等诸多问题;同时,随着国民经济能力提升,群众的需求层次进一步多样化发展,特别是客货运的不同发展需求,迫切需要建设更专业化的道路系统,达到需求与供给的质量匹配和总量平衡。客货分线能有效缓解传统客货混行带来的困扰,国内已有部分道路实施了客货分线,其实际效益也逐步被认可。但由于相关理论及行业规范的缺失,没有详实准确完善的技术作为支撑,导致设计时仍采用客货混行的技术指标,比较盲目随意且不符合实际需要,故加快完善客货分线相关理论,具有里程碑意义。论文通过分析国内外客货分离理论研究与实施状况,确定了论文研究的基本方向,提出了客货分线的概念,确定了专用车道代表车型,探讨了客货分线的优势,并运用层次析法和VISSM仿真对客货分线的适用条件及车道功能划分进行了初步研究。文章重点研究了客货分线几何设计技术指标,根据客货车型不同,应用国内外成熟理论和方法,分别计算研究客车专用道路与货车专用道路的车道宽度、中间带和同向带宽度、纵坡主要参数值、立交型式及交通流组织措施。结合云南小铺至乌龙高速公路共用段改扩建工程项目,利用本文客货分线研究成果,对其实施方案进行重新比选,证明了实施客货分线的可行性和必要性。文章分析了客货分线的优势,构建了客车专用车道和货车专用车道模型,并对其几何设计中的部分重点指标完成了理论计算,为客货分线的发展奠定基础。
[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.
