NOTES: 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.
Directly operated transit is service provided by a public transit agency using
its own employees to operate transit vehicles. Transit service purchased under
contract by a public transit agency is not considered directly operated transit.
