Urban transit systems

North American Industry Classification System code (NAICS): 4851

This industry group comprises establishments primarily engaged in operating local and suburban mass passenger transit systems. Such transportation may involve the use of one or more modes of transport including light rail, subways and streetcars, as well as buses. These establishments operate over fixed routes and schedules, and allow passengers to pay on a per-trip basis (whether or not they also accept payment methods such as monthly passes).
