【摘要】：山地大城市是我国城市结构体系的重要组成部分,很多分布在我国西部地区,如重庆、兰州、攀枝花等。山地城市一般具有地形地貌复杂、城市建设用地紧张、人口高密度聚集等特点。这不仅给城市道路交通系统的建设及规划带来一定的复杂性和特殊性,而且使山地大城市的居民交通出行活动特征不同于一般的平原城市。因此,根据山地大城市的城市形态及路网规划特征、社会经济与文化特征、居民出行习惯特点等,对山地大城市居民交通出行方式选择进行分析,得出不同因素对山地大城市居民出行方式的影响作用,为山地大城市提出相适应的城市道路交通规划对策,优化山地大城市居民出行结构,具有重要的理论研究及实践意义。本论文首先系统分析了山地大城市的居民出行特征、路网形态特征与公共交通服务设施形态特征,总结出了这三大外在影响因素对山地大城市居民出行方式选择的影响,得出了山地大城市交通形态特征与平原城市的差异;其次,分析了影响山地大城市居民步行出行方式、非机动车出行方式、机动车出行方式、公共交通出行方式的各种影响因素、作用范围以及不同出行方式选择的相互作用,得出了山地大城市居民出行方式选择的15种内、外在影响因素,并对各因素对出行方式选择作用的大小进行了初始理论判断;然后,以居民属性、居住区位、出行目的、出行时间、出行方式等出行属性为基础,针对各因素对出行方式选择的作用关系,建立了山地大城市居民出行选择的结构方程(SEM)模型,得到了各出行属性变量间的相互作用关系,以及山地大城市路网特征对出行方式的相关性影响,提出了各因素作用于居民出行方式选择效应的计算方法;最后,以山地大城市重庆的居民出行行为为实例,基于对该市居民出行参数的实际调查,对所建立的结构方程模型进行了应用分析。结果表明,步行路网满意度与步行出行方式呈较强正相关,与非机动车出行呈负相关;非机动车路网满意度与各类交通出行方式选择的效应关系并不明显;城市路网密度与电动/助动/自行车、小汽车、摩托车等出行方式呈正相关,与步行和公交出行呈负相关;路网非直线系数、路网平均纵坡与步行交通方式呈正相关,与摩托车出行方式呈负相关。本论文研究成果对分析山地大城市居民出行方式选择特性、总结山地大城市居民出行方式的影响因素具有较强的理论意义;对指导山地大城市的交通网络建设,合理引导山地大城市居民出行方式选择,建立更加合理有效的山地大城市居民出行方式结构,具有一定的实践指导作用。
[Abstract]:Mountainous cities are an important part of the urban structure system in China, many of them are distributed in western China, such as Chongqing, Lanzhou, Panzhihua and so on. Mountainous cities are generally characterized by complex landforms, tight land for urban construction and high population density. This not only brings some complexity and particularity to the construction and planning of urban road traffic system, but also makes the characteristics of residents' traffic travel in mountainous cities different from those in plain cities. Therefore, according to the characteristics of urban form and road network planning, socio-economic and cultural characteristics, the characteristics of residents' travel habits and so on, this paper analyzes the choice of transportation modes for the residents of mountainous big cities. It is of great theoretical and practical significance to find out the influence of different factors on the travel patterns of the residents in mountainous cities, to put forward appropriate urban road traffic planning strategies for mountainous cities and to optimize the travel structure of residents in mountainous cities. Firstly, this paper systematically analyzes the characteristics of residents' travel, road network and public transportation service facilities in mountainous cities, and summarizes the influence of these three external factors on the choice of travel modes of residents in mountainous big cities. The difference between the traffic form characteristics of mountainous cities and plain cities is obtained. Secondly, the paper analyzes the influence of walking mode and non-motor vehicle travel mode of residents in mountainous big cities. The influence factors of public transportation travel mode, the scope of action and the interaction of different travel modes are obtained. The 15 kinds of internal and external factors affecting the choice of travel mode of residents in mountainous big cities are obtained. Then, based on the resident attribute, residential location, travel purpose, travel time, travel mode and other travel attributes, the paper makes an initial theoretical judgment on the effect of various factors on the choice of travel mode. Then, based on the characteristics of residents, residential location, travel purpose, travel time, travel mode, etc. According to the effect of various factors on travel mode selection, the structure equation (SEM) model of travel choice for residents in mountainous large cities is established, and the interaction relationship among travel attribute variables is obtained. As well as the influence of the road network characteristics on the travel mode, the paper puts forward the calculation method of the influence of various factors on the choice effect of the residents' travel mode. Finally, taking Chongqing, a mountainous city, as an example, the paper takes the travel behavior of the residents in Chongqing, a mountainous city, as an example. Based on the actual investigation of the travel parameters of the residents in the city, the structural equation model is applied and analyzed. The results show that there is a strong positive correlation between pedestrian network satisfaction and walking mode, and negative correlation with non-motor vehicle travel, while the effect of non-motor network satisfaction on various types of travel mode is not obvious. The density of urban road network is positively correlated with electric / auxiliary / bicycle, car, motorcycle and other travel modes, and negatively correlated with walking and public transportation, and the road network is not linear, and the average longitudinal slope of road network is positively correlated with walking traffic mode. It has negative correlation with motorcycle travel mode. The research results of this paper are of great theoretical significance to analyze the characteristics of the choice of trip modes for the residents of mountainous big cities and to summarize the influencing factors of the trip modes of the residents of mountainous large cities, and to guide the construction of transportation network in mountainous cities. It has certain practical guidance function to guide the choice of travel mode and to establish a more reasonable and effective structure of travel mode for residents of mountainous big cities.
