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

There are many features, advantages and benefits to using an APS at your city's intersections.

The driver unit (DUAT811) provides all of the necessary electronics to drive an audio tactile transducer (located in the push button). This system creates the don�t walk and walk audible and tactile signals as specified in the above standards to assist sight and/or hearing impaired pedestrians.
The output level of the audible signals generated by the module automatically and instantaneously increase or decreases depending on the ambient noise level.
There are three different audible tones:
The locating tone: (Don�t Walk) is 1000Hz �50Hz with a repetition rate of 0.55Hz � 0.05Hz
The transition tone: (Walk) starts with a burst at 3500Hz � 500Hz and then decreases exponentially to 700Hz � 100Hz
The crossing tone: (Walk) is 500Hz � 25Hz and the repetition rate is 8.5Hz � 0.5Hz.
It is simple to upgrade standard push button facilities to full audio and tactile systems.

The BPC push button has an audible output that consists of three tones. The locating or "don't walk" tone, the transitional and "walk" tone.
Click here to listen to the different audio tones for each mode.
There is also the option with the BPC push button to have an LED indicator which signals to the hearing impaired that they have placed a call to the controller for a "walk" cycle.
