Transit Boarding Island

ELM-TBI-41
Recommended Element

Transit Boarding Island

A raised platform positioned between a bike lane and the vehicle travel lane at a transit stop, allowing bus or streetcar passengers to board and alight without crossing the bike lane at grade, and without the transit vehicle needing to merge across the bike lane to reach the curb.

Why this pattern exists

Where a protected bike lane runs along a curb that also serves transit stops, a standard curbside stop forces either the bus to cross the bike lane to reach the curb, or passengers to cross the bike lane to board, both creating a recurring conflict point. A boarding island resolves this by placing the stop between the two facilities, letting each operate without crossing the other. This pattern exists to document that specific, well-defined conflict and its resolution.1

Key considerations

Protected Bike Lane/Cycle Track (ELM-PBL-37), Transit Platform (FAC-TPL-02) (the two facilities this pattern reconciles); Detectable Warning Surface (ELM-DWS-10), Curb Ramp (ELM-CRP-03) (companion accessibility elements)
