Why install them?
Intersections and traffic signals have become more complex, and we want to increase safety for pedestrians with hearing and visual impairments to accurately determine the timing of some crossing signals. Read more about accessibility and MnDOT.

What are accessible pedestrian signals?
Accessible pedestrian signals provide directions in alternative formats such as:
- Verbal messages
- Audible tones
- Vibrating surfaces
They also provide pedestrians with information about:
- Existence and location of the pushbutton
- Beginning of the "WALK" interval
- Direction of the crosswalk
Audible signals can be heard six to twelve feet from the pushbutton. Volumes become louder or softer in response to level of traffic noise. Audible signals provide information using:
- Repeating tone indicating location of pushbutton
- Tone, click or spoken "WAIT" indicating button was pushed
- Tone or spoken “WALK” message providing name of street to be crossed
- Spoken countdown of remaining crossing time
Tactile signals are located at the pushbutton. Tactile signals provide information using:
- Raised arrow pointing in direction of travel and vibrating during the “WALK” signal
- Braille symbols providing name of street
- Improve ability of pedestrians with hearing and visual impairments to cross the street safely
- Allow pedestrians to more accurately judge beginning of “WALK” interval
- Reduce crossings begun during “DON’T WALK” phase
