【摘要】：城市客运交通结构是关系城市交通系统发展方向的核心问题。建立城市可持续发展的交通运输系统,不但要考虑交通出行效率目标最大化,还要使交通系统的资源消耗最小,环境污染最低,以打造低碳城市的发展模式。为了减少城市客运的碳排放,本文根据碳足迹理论,通过建立城市交通结构模型对广州市的客运交通结构进行合理优化,基于社会可持续性、经济可持续性和环境可持续性等方面的交通可持续性,以交通系统的社会效率最大化和交通系统内部成本以及环境影响最小化为约束,构建城市客运交通结构模型并进行优化,得出了2020年公交系统(轨道交通与常规公交之和)的分担比例增长至63.5%,其中轨道交通分担比例增长了近12.5%,而小汽车交通及出租车交通的分担比例都有较大程度的降低。该模型从出行特性角度出发,在考虑可持续发展的基础之上,把城市交通需求、资源、能源、环境作为约束条件,较好地体现了当今城市交通的发展态势,为城市客运交通结构优化提供理论支撑,同时根据广州市的交通发展对模型进行了实例验证,应用中取得了良好的效果。
[Abstract]:Urban passenger transport structure is the core problem related to the development direction of urban transportation system. To establish a sustainable urban transportation system, we should not only consider the goal of maximum travel efficiency, but also minimize the resource consumption of traffic system. In order to reduce the carbon emission of urban passenger transport, this paper optimizes the passenger transport structure of Guangzhou by establishing a model of urban traffic structure according to the theory of carbon footprint. Based on social sustainability, economic sustainability and environmental sustainability, traffic sustainability is constrained by the maximization of social efficiency of transport systems and the minimization of internal costs and environmental impacts of transport systems. The model of urban passenger traffic structure is constructed and optimized. In 2020, the share ratio of public transportation system (the sum of rail transit and conventional public transport) increased to 63.5, in which the proportion of rail transit increased by 12.5. and the share of car traffic and taxi traffic increased to a greater extent. This model is based on the travel characteristics, On the basis of considering sustainable development, taking urban traffic demand, resources, energy and environment as constraint conditions, it reflects the development situation of urban traffic well, and provides theoretical support for the optimization of urban passenger transport structure. At the same time, according to the traffic development in Guangzhou, the model is verified by an example, and good results are obtained in the application.
