Demand maturation at new metro stations in Seoul: regular trips, neighboring stations, and forecasting from earlier openings - data, code and Supplemental Materials

Daily station-level demand of new metro stations, mechanism analyses and forecasting benchmark. The deposit contains the processed daily series of 57 new stations of 18 openings in the Seoul metropolitan network (2015-2026) and of 7 new stations of 3 openings in London (2019-2026), derived from open smart card counts of the Seoul Open Data Plaza and the Transport for London station footfall data; the opening events and the station attributes, including counts derived from OpenStreetMap and the distance to the nearest existing station; the results of the mechanism analyses (maturation by day type and time of day, event study of neighbouring stations, hierarchical model with the nearest existing station); the forecast errors of every method compared in the article, by station, opening and forecast origin; the Python code that reproduces every number, table and figure; and the Supplemental Materials of the article (Texts S1-S6, Tables S1-S3, Figs. S1-S4). Raw source files are not redistributed; the code downloads them from the original providers.
