BRT’s advantages as a public transit solution are clear. It mirrors light rail or streetcar service, but at a lower cost, by placing buses into dedicated transit travel lanes, removed from other vehicles. In this way, BRT provides more efficient and reliable service.
BRT implementation means re-designing the streetscape to accommodate not only the new bus lanes and stations, but also other vehicle traffic, parking, pedestrians and—bicycles. What happens when a proposed BRT corridor overlaps with a desirable route for cyclists, with only so much right-of-way to go around? Can BRT and bicycles coexist? And how?
Where do bikes fit into your modal pecking order?
Buses and bikes do not always get along. The friction is most often found in a corridor’s curbside lane. Buses and bikes go about the same speed on average in a city setting, but buses reach higher speeds between their stops. This creates a leapfrog effect: Bicyclists catch up to a bus when it makes its stop. The bikes cautiously pass, and when the bus starts again, it has to pass the bikes, which can impact bus speeds. This is bad for everyone: efficiency suffers and safety issues arise.
BRT designs would ideally relocate bicycle traffic to a parallel street with less traffic and pedestrian street-style conditions, but that is not always an option. Where bicycle use is already high on a proposed BRT corridor, there is danger in creating a similar situation to the one described above. Bicyclists may be drawn to riding in the dedicated transit lanes since they see less traffic, but doing so would increase safety risks for riders and take the “rapid” out of the BRT service.
Each community, therefore, needs to evaluate how high a priority it places on bicycle access. Should the project’s design limit automobile speeds to give priority to the buses and bikes? Will the community accept losing parking to make room for bicycle lanes? Answering these types of questions—as part of the planning process and in community feedback sessions—will establish a pecking order, or modal hierarchy, and determine the overall importance of bicycle facilities to the project.
The Seattle Department of Transportation’s (SDOT) Roosevelt-to-Downtown High-Capacity Transit Study is a good example of when cycling commanded a top spot in the modal hierarchy. In that project, SDOT and the public agreed that bike accommodations along the corridor, for users of all ages and abilities, was more desired than parking. While not all communities will reach that same conclusion, SDOT could incorporate several protected bike lane designs into its plans for their BRT project.
