This bike offramp is intended to keep cyclists out of roundabout traffic. It routes bikes from the roadway to the sidewalk; once they use the crosswalk there’s an on-ramp to move them back to the road.


For a pedestrian who is blind or low-vision and uses a cane, the design is a problem. This pedestrian ‘tracks right,’ using her cane to follow the right edge of the walkway to stay on track. The slight angle of the ramp seems normal at first, and the lack of any tactile change at the roadway means she is well into the oncoming traffic lane and into the raised lane divider before she realizes something is wrong. For this roundabout design there are four such ramps. The day we visited the Warm Springs corridor, we noticed several inattentive drivers on cellphones; at an intersection to the west of this location, several cars flew right through the flashing pedestrian signal. With a silent electric vehicle, there is no warning that a collision is imminent. It’s critical for planners and designers to include a variety of users with different perspectives to review and contribute to designs affecting connectivity, visit ability and safety. We should note that several people were watching traffic to ensure her safety. Her goal was simply to follow the sidewalk heading west as she would normally navigate with a cane.
