What do the Subway Flags in Pokemon Black & White represent?

[Ottozone]

Flag0, Flag1, Flag2, Flag3, and Flag7.

They are given as an option to turn on/off but I don't know what they do. Tried looking in past forums but couldn't find any info on them. I have attached my subway data here. I haven't messed with the flags in PkHex, but wondering how they get triggered in game and what they do. Any help is appreciated.
