Look books up on Google Books, see how many references there are to transportation terms like "bus" or "subway."
For tv shows, look for recap sites, and use Google Advanced search to determine if that site or domain regularly mentions the show and transportation keywords.
For all types of media, look for reviews of the works and see if the reviews mention either the city or transportation as a key theme.
