For Blind or Visually Impaired Pedestrians

An Accessible Pedestrian System is an audio and tactile system that gives you Accessible crosswalks and helps to make your city pedestrian friendly.

This APS provides much of the information already available to sighted pedestrians to vision impaired pedestrians. An APS from BPC provides the vision impaired pedestrian with the following information:

That an intersection is Accessible
The location of the button and the need to actuate the button to get a walk cycle
Which button applies to which crosswalk
Indicates to the user that they have placed a call to the controller for a "walk" cycle
Whether the crosswalk is in a "walk" or "don't walk" phase
When the "walk" phase begins
When the clearance or "don't walk" phase begins
