发布时间：2018-08-20 17:20
【摘要】：近年来,随着我国城市居民生活水平的提高,交通出行需求问题越来越突出,利用有限的土地资源建立完善的公共交通系统是解决这一需求问题的关键,而合理规划常规地面公交线网更能实现城市土地资源的有效利用。可达性作为评价公共交通系统服务水平的一个重要指标,不仅可以用来评价公交线网结构布局现状,还可以为更好地进一步优化公交线网起到重要的现实意义。本文基于可达性理论基础,将常规公交线网可达性定义为出行者通过常规地面公交从出发点到达目的地获得的广义综合效用,并从该定义出发,分析了出行者交通出行需求及常规公交线网可达性主要影响因素。根据出行者特性和常规公交出行特性,对居民常规公交出行乘车线路选择行为进行研究分析,建立了包括出行者特性、出行时间、换乘次数、公交服务质量、公交线网连通性等变量的多元Logit模型。该模型以随机效用理论为理论基础,以离散选择模型为框架结构。采用SP/RP组合调查法获取模型所需数据,然后用SPSS统计软件处理调查数据,对多元Logit模型中的未知参数进行标定和验证,最后得出文中所建模型能够较为精确地对居民常规公交出行决策行为进行描述,并适用于城市常规公交线网可达性评价。
[Abstract]:In recent years, with the improvement of living standards of urban residents in China, the problem of transportation travel demand is more and more prominent. The key to solve this problem is to use limited land resources to establish a perfect public transportation system. The rational planning of conventional ground transit network can realize the effective utilization of urban land resources. As an important index to evaluate the service level of public transportation system, reachability can not only be used to evaluate the present situation of bus network structure, but also play an important practical significance for better optimization of public transport network. Based on the theory of reachability, this paper defines the reachability of conventional public transit network as the generalized comprehensive utility that travelers get from the starting point to the destination through the conventional ground transit, and proceed from this definition. The main influencing factors of travelers' travel demand and the accessibility of conventional bus network are analyzed. According to the characteristics of travelers and regular public transportation, this paper studies and analyzes the behavior of residents' choice of bus route, and establishes the characteristics of travelers, travel time, transfer times, and the quality of public transport service. Multivariate Logit model of bus network connectivity and other variables. The model is based on the stochastic utility theory and the discrete selection model as the frame structure. The data needed by the model are obtained by SP/RP combined survey method, and then processed by the SPSS statistical software, and the unknown parameters in the multivariate Logit model are calibrated and verified. Finally, it is concluded that the model can accurately describe the decision-making behavior of residents' conventional public transport travel, and can be used to evaluate the accessibility of urban conventional transit network.
