CDOT shows preferred designs for bus stops beside protected bike lanes, committee raises accessibility concerns
Summary
Chicago Department of Transportation staff presented designs that separate pedestrians, raised bike lanes and bus loading areas using tactile directional indicators and detectable warning surfaces; committee members urged additional user testing with disability organizations and coordination with the Mayor’s Office for People with Disabilities.
Brad Topol, a CDOT streets program representative, presented design approaches for locations where raised or protected bike lanes run adjacent to bus stops. The presentation outlined treatments intended to separate pedestrian flows from bicycle traffic while leaving sufficient room for wheelchair ramp deployment and ADA maneuvers within bus loading areas.
Topol showed several configurations: a shared boarding area with a narrow boarding island and a raised bike lane at sidewalk level; a full‑width bus island at sidewalk level separated from the bike lane by curb and detectable warnings; and examples that add tactile directional indicators (TDIs) and trapezoidal detectable surfaces to guide people with vision impairments to designated crossing points.
CDOT told the committee that designers prefer positive wayfinding (TDIs, corduroy or flat‑top bars) offset from bike lanes by 12–24 inches so a cane user can detect the edge of the pedestrian access route. Topol cited examples and research from other U.S. cities and noted that PROWAG does not fully specify these treatments; CDOT is adapting international and peer‑city practice as standards evolve.
Committee members, including people who use wheelchairs and blind riders, expressed concern that some narrow shared boarding areas could make ramp deployment and boarding feel risky, and urged on‑the‑ground testing with mobility‑aid users. Topol said CDOT coordinated earlier designs with the Mayor’s Office for People with Disabilities (MOPD) and that the department will continue to refine standards and request input from the ADA Access Board and disability organizations.
Why it matters: As cities add protected bike lanes and prioritize multiple modes, design choices at bus stops affect safety and accessibility for riders who use wheelchairs, canes or other mobility aids. Committee members requested stronger coordination with disability advocates, targeted user testing and clear standards for detectable edges and crossings.
