NOTE: 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.
