A curated data set of L-space representations for 51 metro networks worldwide

A curated data set of L-space representations in .json format for 51 metro networks worldwide. The creation of this data set was part of the MSc thesis referenced below. The goal for the data was to create a set of topological representations based on GTFS data that is curated and verified. Each file is a graph, containing a set of nodes and edges for each network along with some additional information. The information on the number of vehicles is based on a representative day for the period of 05:00 until 23:59. The representative day chosen for each network along with information about the processing can be found in metadata.xlsx

本数据集为全球51条地铁网络的L空间（L-space）表示经整理甄选后的数据集，采用JSON格式存储。本数据集的构建系下述参考文献所载硕士学位论文的研究内容之一。本数据集旨在基于经过整理与核验的通用交通馈送规范（General Transit Feed Specification）数据，构建一套拓扑表示集合。每个文件对应一张拓扑图，包含对应地铁网络的节点、边集合及若干附加信息。车辆数量相关统计数据基于各地铁网络选定的代表性运营日中5:00至23:59时段的运营数据生成。各地铁网络所选定的代表性运营日，以及数据处理相关的详细信息，均可在metadata.xlsx文件中查阅。
