This project prints out the nearest station where the restroom is located within the turnstile gate, depending on the station and direction you choose.
When you were on the subway,
- when the distance to the destination is quite long
- when you don't know the geography around you
You can't wait to go to the bathroom,
- When you don't want to get off at any station and be in a crowded situation,
- When you don't want to pay for transportation twice,
This program was designed to get to the bathroom as quickly as possible without paying for transportation again in a less crowded environment.
