国土数値情報 鉄道データ N02
（国土交通省）を加工して作成。Matched to stations, routed and simplified — not the original dataset.
Frequencies 運行頻度
Departures per hour derived from GTFS / GTFS-JP feeds published by operators and
gtfs-data.jp, and from the
公共交通オープンデータセンター (ODPT). Currency and accuracy are not
guaranteed, and questions about this app belong in
this repository, not with the operators.
Travel times are estimated from distance, not read from timetables, and express
services are not modeled. Don't use this for navigation or for trip planning that matters.
