+title = "Bus and metro networks of Chinese cities (CPTOND-2025)"
+description = """Bus networks of 350 cities and metro networks of 46 cities in mainland China, Hong Kong and Macao (and one metro network of Taiwan, `taiwan_metro`, around Taipei), from the China Public Transport Operation Network Dataset (CPTOND-2025) compiled by L. Wang, H. Wei, Y. Guan and collaborators. The routes and stops were collected in June 2025 by systematically enumerating the routes listed by the public transport information platform 8684 (8684.cn) and retrieving their courses, stops and operational attributes from the Amap (Gaode) map API; the coordinates were converted from the Chinese GCJ-02 system to WGS 84. The English names of stops and cities in the data are automatic translations of the Chinese names, and some are mistranslations (e.g. the city of Jixi, 鸡西, appears as "Chicken West", and Dezhou, 德州, as "Texas").
+
+There is one network for each city and mode, named after the city, in pinyin without tones, and the mode (e.g. `beijing_bus`, `beijing_metro`, `jixi_bus`, `xianggang_metro`), since the English names of the data are automatic translations, some of them wrong (e.g. "Chicken West" for 鸡西, Jixi); the five pairs of cities with the same name in pinyin are told apart by their province (e.g. `fuzhou_fujian_bus` for 福州 and `fuzhou_jiangxi_bus` for 抚州); the network properties `city_cn` and `city_en` give the city's name. A node is a stop (bus stop or metro station, deduplicated over the routes of the city), and a directed edge from stop $i$ to stop $j$ means that some route serves $j$ immediately after $i$; the edges are the segments between consecutive stops provided by the authors, aggregated over the routes and directions, with the number of routes passing through them. Some segments join a stop to itself (9,853 self-loops over all networks), presumably where consecutive stops of a route share the same stop id. The courses of the segments and routes (as polylines) are not included, and neither are the routes themselves with their operational attributes (operating hours, fares, companies). The dataset has two versions on figshare (July and September 2025); the second, used here, separates the bus networks of five pairs of cities with the same name in pinyin (Fuzhou, Suzhou, Taizhou, Yichun and Yulin), which are merged in the first.
+
+The networks have the following properties:
+
+- Nodes: `name`, the name of the stop (Chinese); `name_en`, its (automatic) English translation; `stop_id`, its id in the data; `num_routes`, the number of routes serving it (counting the two directions of a route separately); `latitude` and `longitude`, its position.
+- Edges: `num_routes`, the number of routes passing through the segment; `distance`, its length along the route (km).
+- Network: `city_cn` and `city_en`, the name of the city in Chinese and (automatically translated) in English; `mode`, `bus` or `metro`."""
