Transit Stop or Stop Zone
The stop zone is the space designated for the waiting and boarding of transit riders and can be integrated into the sidewalk, the median, or on a dedicated boarding island.
When curbside, the stop zone is adjacent to the pedestrian clear path.Shelters, seating, signs, and transit information must be located so as not to impede pedestrian accessibility.The stop zone may also be aligned with the parking lane or cycle lane, and may include green infrastructure or other curbside amenities at non-stop locations.
Transit Running Way
Most transit vehicles are 2.4–2.8 m wide, excluding mirrors; a 3 m width allows for a comfortable low-speed operating space, so long as there is flexible buffer space adjacent to the transit running way (such as a parking lane, cycle facility, or marked buffer). When operating along the curb or in a bidirectional transit configuration, a 3.3–3.5 m width allows for comfortable operation with low risk for mirror clips or sideswipes. Designate exclusive transit running way with pavement markings and signs.
Buffer Zone
The buffer zone may simply be extra roadway width assigned to the transit lane, or may be more defined, such as medians or marked/constructed buffer. Vertical features must not interfere with safe transit operation.
