Bus bulb
Avancée de trottoir pour bus
Bus bulb is a sidewalk extension at a bus stop that allows a bus to serve passengers without pulling fully into a curbside parking lane. It can expand waiting space and reduce re-entry delay, while its geometry must support accessible boarding and safe interactions with cycling.
Understanding the term
A bus bulb is a stop layout, not a service frequency measure. Assess platform crowding and the path between the boarding edge and the surrounding sidewalk.
Design assessment should follow the complete paths of people and vehicles through the location. Check visibility, drainage, accessible passage, delivery handling, and maintenance under realistic operating conditions. An apparently adequate plan can fail when doors open, vehicles turn, or queues form. Record site constraints and the governing design guidance, then review the arrangement after installation so that changing activity and seasonal conditions do not invalidate the intended function.
