A bus bulb, also called a bus boarder, bus border, bumpout, bus cape,[1] or a kerb outstand is an arrangement by which a sidewalk or pavement is extended outwards for a bus stop; typically the bus bulb replaces roadway that would otherwise be part of a parking lane. With bus bulbs or boarders, a bus can stay in its traffic lane to discharge and pick up passengers, instead of having to pull over to the curb.
The term bus bulb is prevalent in North American usage, whilst bus boarder or bus border is used elsewhere.[2][3][4]
A bus bulb or boarder can be considered as a specific form of curb extension, although that term is more normally used to describe a sidewalk extension for the purposes of traffic calming or other traffic management purposes.
