Public Transportation - Shanghai

Whereas Beijing is an relatively orderly mass of centrally managed bus lines by a single organization, Shanghai appears to be plates of spaghetti, linguini, angel hair and other pasta messes cooked up who knows why.  Since I'm not in Shanghai, I'll post what I can find, and leave it to Shanghai locals to repair the damage as they see fit.
