本研究基于FCD(浮动车数据),采用全局空间自相关分析方法,研究各个等级道路的空间相关性的关系,探讨城市不同等级道路之间的空间关联的内在规律,研究结果表明各个等级道路路段交通状态空间相关性系数存在差异,路段交通状态的空间相关性系数越大说明路段交通状态的相互影响程度越大,即拥堵路段对周边路段交通状态的影响程度越大.本研究得到快速路以及主干道的路段交通状态空间相关性系数较其他等级道路大,支路的路段交通状态空间相关性系数较其他等级道路小,即快速路和主干道的拥堵路段对周边道路影响较大.研究结果为梳理城市交通拥堵,合理分配有限的交通管理资源提供理论依据,对城市交通管理有借鉴意义.

基于机会累计的公交网络时空约束评价模型

本文提出的基于机会累计的公交网络时空约束评价模型突破了传统的公交网络设施供给评价框架体系,从城市用地开发和乘客出行需求出发,以通过公交网络可获得的累计机会数量来表示公交网络通达能力,并以城市公交网络期望服务能力和出行时间阈值为时空约束条件,给出城市公交网络综合评价思路和指标定义,最后以上海浦东金融城为实证分析对象,将评价模型应用于实践,计算结果表明公交网络服务能力与城市用地功能布局密切相关,而公交

大城市边缘区外来人口分布特征及因子研究--以北京北部边缘区为例

随着全球化的发展,我国城市化进程加快,城市用地外侵扩张迅速,在老城区和远郊区间形成犬牙交错的城市边缘区.该区域由于外来人口集中、用地布局碎片化以及交通规划指向性强等特点,形成了较为典型的交通问题.本文的目的在于,通过外来人口的分布特征及影响因子研究,分析其内在需求,从而提出相关建议以解决交通问题.首先通过GIS的空间统计方法,将北部边缘区的人口属性空间化,判断居民结构及出行需求特点:再通过SPSS
