Bus station  A bus station is a structure where city or intercity buses stop to pick up and drop off passengers. While the term bus depot can also be used to refer to a bus station, it generally refers to a bus garage. A bus station is larger than a bus stop, which is usually simply a place on the roadside, where buses can stop. It may be intended as a terminal station for a number of routes, or as a transfer station where the routes continue. Bus station platforms may be assigned to fixed bus lines, or variable in combination with a dynamic passenger information system. The latter requires fewer platforms, but does not supply the passenger the comfort of knowing the platform well in advance and waiting there. An accessible station is a public transportation passenger station which provides ready access, is usable and does not have physical barriers that prohibit and/or restrict access by people with disabilities, including those who use wheelchairs.
