城市路网布局结构对公共交通出行的影响

Effects of urban road network layout structure on public transportation trips

以路网的介数中心势量化路网的布局结构,选取我国29个城市为样本,建立多元线性回归模型进行人均公交出行次数的对数对介数中心势的回归。结果显示:城市路网布局结构与居民使用公共交通程度存在显著的相关性,城市路网介数中心势越大,即该路网越具有中心化趋势,城市居民人均公交出行次数越多,居民的公共交通使用程度越高。在发展公共交通时应注重通过形成轴向发展的集中化的路网布局结构来促进居民对公共交通的使用。

In order to understand the impact of urban road network layout and structure of public transportation to the road network betweenness centralization to quantify different structural layout of the road network, a sample of 29 cities was selected to establish a multiple linear regression model for logarithmic average bus travel times of betweenness centralization return. Results showed that the urban road network layout structure and residents use of public transportation extent had a significant correlation with the urban road network betweenness centralization, that was, the more the road network with a central tendency and urban residents per capita bus travel times, the higher the level of public transport used. The development of public transport should pay attention to the road network by forming a centralized layout structure to promote axial residents to use public transport.
