Trainspotting:交通和交通网络拓扑的提取和分析

Trainspotting: Extraction and Analysis of Traffic and Topologies of Transportation Networks

Maciej Kurant, Patrick Thiran

摘要:

了解现实生活中的交通模式对于理解和分析交通系统至关重要。这一数据相当罕见。在本文中,我们提出了一个算法提取的实际物理拓扑结构和网络的交通流从公共交通系统的时刻表。我们将此算法应用于三个大型交通网络的时刻表。这使我们能够系统地比较三种不同的方法来构建交通网络的图形表示;所得到的图形是根本不同的。我们还发现,现实生活中的交通模式是非常异质性,无论是在空间和交通流强度。

英文摘要:

The knowledge of real-life traffic pattern is crucial for good understanding and analysis of transportation systems. This data is quite rare. In this paper we propose an algorithm for extracting both the real physical topology and the network of traffic flows from timetables of public mass transportation systems. We apply this algorithm to timetables of three large transportation networks. This enables us to make a systematic comparison between three different approaches to construct a graph representation of a transportation network; the resulting graphs are fundamentally different. We also find that the real-life traffic pattern is very heterogenous, both in space and traffic flow intensities.
