Chungjeongno Station in Seoul is a transit hub where Line 2 and Line 5 meet. Bus riders need to check which stop they board at and which stop they get off at, and the station carries a large number of public transit users. The transfer route between Line 2 and Line 5 follows a winding slope. Exits 1 and 2 have only stairs, which makes them difficult to use with wheelchairs and strollers.
