A bus stop is a designated place where buses stop for passengers to board or alight from a bus. These are normally positioned on the highway and are distinct from off-highway facilities such as bus stations. The construction of bus stops tends to reflect the level of usage. Stops at busy locations may have shelters, seating, and possibly electronic passenger information systems; less busy stops may use a simple pole and flag to mark the location. Bus stops may be clustered together into transport hubs allowing interchange between routes from nearby stops and with other public transport modes.
For operational purposes, there are three main kinds of stops: Scheduled stops, at which the bus should stop irrespective of demand; request stops (or flag stop), at which the vehicle will stop only on request; and hail and ride stops, at which a vehicle will stop anywhere along the designated section of road on request.
Certain stops may be restricted to "discharge/set-down only" or "pick-up only". Some stops may be designated as "timing points", and if the vehicle is ahead of schedule it will wait there to ensure correct synchronization with the timetable. In dense urban areas where bus volumes are high, skip-stops are sometimes used to increase efficiency and reduce delays at bus stops. Fare stages may also be defined by the location of certain stops in distance or zone-based fare collection systems. Sunday stops are close to a church and used only on Sundays.
The first ever recorded bus stop was in Bishops Stortford and was believed to be constructed in 1890, linking Bishops Stortford to the town of Colchester.
Bus stop infrastructure ranges from a simple pole and sign, to a rudimentary shelter, to sophisticated structures. The usual minimum is a pole mounted flag with suitable name/symbol. Bus stop shelters may have a full or partial roof, supported by a two, three or four sided construction. Modern stops are mere steel and glass/perspex constructions, although in other places, such as rural Britain, stops may be wooden brick or concrete built.Bus stop in Western Isles
