【摘要】：随着我国城市化水平的快速发展,现有城市道路的交通能力和服务功能已无法满足居民的出行需要。而以绿色、生态为导向的城市道路横断面提倡绿色环保型出行方式,可缓解道路拥挤、减少环境污染,保证资源合理利用。目前,国内外对城市道路横断面布置的研究较多,并提出了一些相关技术标准,但较为零乱,尚不系统;有关绿色生态型城市道路横断面的实际标准与优化体系方面更是空白。因此,建设以绿色、生态为导向的横断面形式具有重要的现实意义。本文全面分析了城市道路横断面影响因素及设计中存在的问题,确定了典型绿色生态型城市道路横断面形式,建立了基于模糊重构优化DEA方法的评价模型。主要研究内容如下所示:(1)全面研究了城市道路横断面基本形式及其道路功能,从道路等级和功能、交通噪音和安全、道路景观和绿化、交通流特征等方面提出了目前城市道路横断面设计的不足,为绿色生态型城市道路横断面设计奠定了坚实的理论基础。(2)确定了基于交通流量的绿色生态型城市道路横断面选择标准及布置形式,系统分析了城市道路横断面组成要素及其设置要求,在此基础上提出了典型绿色生态型城市道路横断面形式。(3)构建了绿色生态型城市道路横断面影响评价指标体系,在模糊重构的基础上,提出了两种思路对传统的DEA模型进行优化,保证了绿色生态型城市道路横断面评价的顺利实施。
[Abstract]:With the rapid development of urbanization in China, the traffic capacity and service function of existing urban roads can no longer meet the travel needs of residents. The green and eco-oriented urban road cross section advocates green and environment-friendly travel mode, which can alleviate road congestion, reduce environmental pollution and ensure the rational use of resources. At present, there are many researches on the layout of urban road cross section at home and abroad, and some related technical standards are put forward, but they are not systematic, and the actual standards and optimization system of green ecological urban road cross section are blank. Therefore, the construction of green, ecological-oriented cross-section form has important practical significance. In this paper, the influencing factors of urban road cross section and the problems existing in the design are comprehensively analyzed, the typical green ecological urban road cross section form is determined, and the evaluation model based on fuzzy reconstruction optimization DEA method is established. The main contents of the study are as follows: (1) A comprehensive study of the basic form of urban road cross-section and its road functions, from road grade and function, traffic noise and safety, road landscape and greening, Traffic flow characteristics and other aspects of the current urban road cross-section design deficiencies, It lays a solid theoretical foundation for the design of green ecological urban road cross section.) it determines the selection standard and layout form of green ecological city road cross section based on traffic flow. Based on the systematic analysis of the elements of urban road cross section and its setting requirements, this paper puts forward the typical green ecological urban road cross section form. 3) and constructs the green ecological urban road cross section impact evaluation index system. On the basis of fuzzy reconstruction, two ways of thinking are put forward to optimize the traditional DEA model to ensure the smooth implementation of the green ecological urban road cross-section evaluation.
