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

A curated data set of P-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

本数据集为面向全球51个地铁网络的P空间表示（P-space）数据集，采用JSON格式存储且经过整理筛选。本数据集的构建属于下述硕士学位论文研究工作的一部分，其核心目标是基于经整理验证的通用交通提要系统（General Transit Feed Specification，GTFS）数据，构建一套拓扑表示集合。每个文件对应一张图，包含对应地铁网络的节点、边集合以及若干附加信息。车辆数相关统计信息基于时段为5:00至23:59的代表日数据。各地铁网络所选代表日以及数据处理相关详情，均可在metadata.xlsx文件中查阅。
