Besides the obvious "surveilance and punishment" approach, the other politically incorrect but sometimes proven effective approach is raise public transportation prices a lot and then subsidize it if you have a stable job, a family, no criminal record, etc, etc. Of course this includes the word "subsidize" so it may be politically charged as a proposal in the USA, or so I've heard.
