A curated data set of P-space representations for 61 East Asian metro networks

A curated dataset of P-space representations in .json format for 61 metro networks in East Asia. Network structures are built from non-English open data rather than standard GTFS feeds and harmonized into a consistent topological format. Primary sources are ktdb.go.kr for Seoul, Busan, Daegu, and Incheon; tdx.transportdata.tw for Taipei, Taoyuan, Taichung, and Kaohsiung; odpt.org for Tokyo, Yokohama, Kyoto, Kobe, Sapporo, Sendai, and Fukuoka; and lbs.amap.com (a Chinese local map provider) for the remaining 47 systems. Since the raw data sources are often in Japanese, Chinese, or Korean, language skills may be required if exact station names or local conventions are of interest.

本数据集为东亚61个城市轨道交通网络的P空间表征（P-space representations）精选数据集，采用JSON格式存储。其网络结构并非源自标准通用交通馈送规范（General Transit Feed Specification，简称GTFS）数据源，而是依托非英语开放数据构建，并被统一规整为标准一致的拓扑格式。本次数据集的主要数据源包括：针对首尔、釜山、大邱及仁川的ktdb.go.kr；针对台北、桃园、台中与高雄的tdx.transportdata.tw；针对东京、横滨、京都、神户、札幌、仙台及福冈的odpt.org；以及针对剩余47个轨道交通系统的lbs.amap.com（中国本土地图服务提供商）。由于原始数据源多采用日语、中文或韩语编写，若需获取精准的站点名称或遵循当地使用惯例，则需具备相应的语言能力。
