公共交通网络:实证分析与建模

Public transport networks: empirical analysis and modeling

C. von Ferber, T. Holovatch, Yu. Holovatch, V. Palchykov

摘要:

我们使用复杂网络的概念来分析城市公共交通网络(PTN)的统计特性。为此,我们提出了一个全面的调查PTNs的统计特性的基础上的数据,到目前为止未开发的网络规模的14个城市。在我们的分析中特别有用的是不同的网络表示。在一个全面的方法,我们计算PTN的特点,在所有这些表示,并进行比较分析。以这种方式获得的标准网络特征通常对应于对给定城市中使用公共交通的乘客具有实际重要性的特征。解决了PTNs和具有类似传输功能的网络(如嵌入2D或3D空间的神经元,电缆,管道,血管网络)所特有的特定功能。基于实证调查,我们提出了一个模型,虽然是足够简单的是能够重现许多已确定的PTN属性。这个模型的一个核心组成部分是一个增长动力学的自我回避步行代表的路线。

英文摘要:

We use complex network concepts to analyze statistical properties of urban public transport networks (PTN). To this end, we present a comprehensive survey of the statistical properties of PTNs based on the data of fourteen cities of so far unexplored network size. Especially helpful in our analysis are different network representations. Within a comprehensive approach we calculate PTN characteristics in all of these representations and perform a comparative analysis. The standard network characteristics obtained in this way often correspond to features that are of practical importance to a passenger using public traffic in a given city. Specific features are addressed that are unique to PTNs and networks with similar transport functions (such as networks of neurons, cables, pipes, vessels embedded in 2D or 3D space). Based on the empirical survey, we propose a model that albeit being simple enough is capable of reproducing many of the identified PTN properties. A central ingredient of this model is a growth dynamics in terms of routes represented by self-avoiding walks.
