【摘要】 为了满足北京市交通治理精细化的工作需求,需要建立面向街道的交通指数计算模型和分析方法.本文首先对比了不同交通指数计算模型在不同区域范围的适用性,确立了采用行程时间比计算街道交通指数的方法;其次,采用系统聚类的方法,对北京市东城区、西城区共32个街道的交通指数进行了聚类,得出5种具有代表性的典型特征的街道指数模式曲线,并从出行特征、交通需求和用地类型的角度,对每种模型曲线进行了分析,总结其运行特征.更多还原

【Abstract】 In order to meet the work needs of Beijing traffic management refinement,it is necessary to establish calculation models and analysis methods about the community-oriented traffic performance index. This paper first compares the applicability of different traffic index calculation models in different regions,and establishes the method of calculating the community-oriented traffic performance index by using the travel-time ratio. Secondly,using the system clustering method,this paper analyzed traffic indexes for a total of 32 communities in the Dongcheng District and Xicheng District of Beijing. Five models were obtained with typical traffic characteristics,and the curves of each model were analyzed from the travel characteristics, traffic demand and land use function to summarize their operation characteristics.更多还原
