- Most transfer stations are located at places which have large floating population. The subway lets passengers know the location of transfer stations through an announcement for their accommodation, but it is not enough for passengers who concentrate on other things on a subway.

- Vibration occurs at regular intervals on transportation using tracks like the subway. Making vibration on purpose provides passengers with information about a transfer station. A station can convey information more clearly by adding vibration to verbal announcement.
