I think it really does have potential. I'm sure some cities don't have decent public transportation page, so I guess it should go there. Or of course intercity bus travel agencies might be interested in this.
Great name, as others said you will have little trouble selling it. Also for developing purposes, perhaps a website about bus fares etc across different companies, global?
It's a common phrase so that's good. Too bad it's a .net. It's possible usage is pretty obvious. Btw, I noticed the plural is for sale for $849. That's a little high and I think yours isn't worth that either. Maybe low $xxx.
