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 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.
