Motor Bus Transit Route Mileage

Notes: 

Motor bus includes commuter bus, bus, bus rapid transit, and trolleybus. Directional route-miles is the mileage in each direction over which public transportation vehicles travel while in revenue service.  Directional route-miles are a measure of the facility or roadway, not the service carried on the facility, such as the number of routes or vehicle-miles.  Directional route-miles are computed with regard to direction of service, but without regard to the number of traffic lanes or rail tracks existing in the right-of-way.  Exclusive right-of-way refers to lanes reserved at all times for transit use and other high occupancy vehicles (HOVs).  Controlled right-of-way refers to lanes restricted for at least a portion of the day for use by transit vehicles and other HOVs.  Mixed right-of-way refers to lanes used for general automobile traffic. Route-miles are assigned to the state of the transit agency's headquarters.
