【摘要】 目前,随着经济的飞速发展,城市交通拥堵日益严峻,而城市轨道交通的出现及其快速发展极大的缓解了城市道路的出行压力,为居民提供了更加选择多样化的出行方式。对现有城市的轨道交通线网规模进行计算并评价,与城市的整体布局和长远规划息息相关。本文从如下几个方面进行研究：第一,介绍了线网规模的含义,分析了其主要影响因素,并对各影响因素的作用机理进行剖析,得出多层次递阶结构模型；第二,总结了当前几种线网规模计算方法(服务水平法、交通需求分析法、回归分析法、吸引范围几何分析法)的优缺点与适用条件,在此基础上运用非集计思想来标定覆盖范围；第三,系统的介绍了非集计模型的理论基础、基本模型及其目前在交通领域中的应用；第四,建立非集计模型并计算出行分担率。由于交通出行行为调查是分析居民出行行为特征和规律以及建立非集计模型的基础,因此本文从出行特性、出行者个人特性以及交通设施服务水平三个方面对居民出行方式选择的影响因素进行了详细地分析,选择时间T和费用F作为变量,应用非集计模型理论与重庆市核心区居民出行方式调查数据,建立MNL模型并计算,得到出行分担率。最后,运用出行分担率对重庆市核心区实例加以分析,对其现有的城市轨道交通线网规模进行评价。更多还原

【Abstract】 Nowadays with the rapid development of economy, the congestion of urban traffic is more and more serious. As the appearance and rapid development of urban rail transit, the traveling pressure of the urban road has been greatly eased, and provides the residents more diversity choice of transportation. Calculating and evaluating on the scale of existing urban rail transit network is closely linked with the city’s overall arrangement and long-term plan.This article researches from the following several aspects:First, introduces the concept of the scale of transit network, analyzes its main influence factors and their mechanism, then gets multi-layer hierarchical structure model.Second, summarizes the current calculation method (service level method, traffic demand analysis method, regression analysis method, and the attract scope geometry analysis) of the scale of transit network, analysis their advantages, disadvantages and applicable condition. Based on this, puts forward the concept of disaggregate.Third, systematically introduces the disaggregate model its basic theory, basic model and its current applications in traffic;Fourth, establish disaggregate model and calculate the share rate of traffic. As the investigation of the trip behavior is the foundation of analyzing the characteristic and regular pattern of residents travel behavior and modeling the disaggregate mode, this article analysis the influence factors of trip option from travel characteristics, travelers’ personal characteristics and traffic facilities and service level these three aspects. Choose representative of the factors:time and found as variables, apply the theory of disaggregate model and the survey data of residents travel ways in core zone of Chongqing area, establish the MNL model and get the share rate of traffic ways through calculation。At last, evaluate existing urban rail transit network scale in Chongqing by share rate of traffic ways. Evaluate the existed urban rail transit network scale.更多还原
