It’s often necessary for passengers to transfer from one bus route to another during a journey. This is particularly common where routes are linked to operate across the city center. Some systems are designed on the hub-and-spoke principle requiring a high proportion of passengers to transfer at central points.
At points where large numbers of passengers regularly transfer, facilities such as purpose-built off-road bus stations, or roadside bus stops with shelters, perhaps linked by pedestrian bridges or subways, should be provided.
Bus stations should be located so buses do not have to deviate significantly from their routes.
However, with good route planning, it should be unnecessary for the majority of passengers to transfer between bus routes in the city centre, and extensive interchange facilities should not be required. Off-street bus stations in city centers are, in any case, often a wasteful use of expensive land. Although this may be offset by the development of property above the station.
Poor interchange facilities will aggravate the inconvenience for passengers of having to transfer from one bus route to another.
