【摘要】：随着城市人口的迅猛增长,城市用地规模的逐渐扩大,市区用地不断向四周蔓延,城市居民出行的需求也不断增加。在这种背景下,城市轨道交通容量大、环保、快捷的特性,提升了城市交通业的服务水平、改善了居民出行质量和效率、有效减少了私家车出行数量、缓解了城市拥堵和污染情况,对节能减排、实现可持续发展具有现实意义。近年来,城市轨道交通建设在我国已进入蓬勃发展的时期。城市轨道交通的建设受社会政治经济条件的制约,选择适宜于城市规模和交通形态的线网规模一直是国内外研究的重点。城市轨道交通的合理线网规模决定了其与城市地域、经济、人口和出行的平衡关系。本文首先介绍了城市轨道交通的技术经济特性和类型,然后对线网的类型和线网规划的主要内容做了梳理,最后考虑轨道交通与城市的协调发展,分析了人口和城市形态布局对城市轨道交通线网的影响。根据城市轨道交通规划的目标和分析指标,将线网长度作为分析线网合理性的重要标准。本文利用层次分析法,对影响轨道交通线网规模的因素进行分析,得出影响线网规模的递阶层次结构。并详细分析了人口与城市轨道交通线网规模的关系。然后,利用神经网络获得各因素的影响权重。基于影响因素层次分析中城区人口、城区面积、地区生产总值(GDP)三个可量化的指标,提出以下三种方法计算城市轨道交通线网合理规模：1、基于城区人口规模的出行需求法；2、基于城区面积的服务水平法；3、基于地区生产总值(GDP)的成本效益法。然后,结合神经网络得到的影响权重,得出兼顾城区人口、城区面积、地区生产总值(GDP)三个方面的城市轨道交通线网合理规模。利用本文得到的线网合理规模计算模型,具体分析内江市城市轨道交通的合理线网规模,为内江市城市轨道交通的建设者提供了较有价值的规划意见。
[Abstract]:With the rapid growth of urban population, the scale of urban land is gradually expanding, the urban land is spreading to the surrounding area, and the demand for urban residents is increasing. In this context, the large capacity, environmental protection and fast characteristics of urban rail transit have improved the service level of urban transportation and improved the quality and efficiency of the residents' travel. In recent years, the construction of urban rail transit has entered a period of vigorous development in China. The construction of urban rail transit is restricted by social and political and economic conditions, and it is suitable for urban scale and traffic. The scale of line network has always been the focus of research at home and abroad. The rational line network size of urban rail transit determines its balance with urban area, economy, population and travel. This paper first introduces the technical and economic characteristics and types of urban rail transit, and then combs the types of line network and the main content of line network planning. Finally, considering the coordinated development of urban rail transit and city, the influence of population and urban layout on urban rail transit network is analyzed. According to the target and analysis index of urban rail transit planning, the length of line network is regarded as an important criterion for the rationality of line network analysis. The factors that affect the scale of the network scale are analyzed, and the relationship between the population and the urban rail transit network scale is analyzed in detail. Then, the influence weight of the factors is obtained by using the neural network. Based on the influence factor level analysis, three quantifiable indexes of urban population, urban area and GDP are proposed. The following three methods are given to calculate the reasonable scale of urban rail transit network: 1, the travel demand method based on urban population size; 2, service level based on urban area; 3, based on the cost-benefit method based on GDP. Then, combining with the weight of the response of the neural network, the urban population, urban area and regional population are obtained. The rational scale of urban rail transit network in three aspects (GDP) is used to analyze the reasonable scale of urban rail transit in Neijiang by using a reasonable scale model obtained in this paper, which provides a more valuable planning opinion for the builders of urban rail transit in Neijiang.
