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 and "customary stops" have no
specific infrastructure being known by their description. Bus stops may be clustered together into transport hubs allowing
interchange between routes from nearby stops and with other public transport modes.
