AAPS Advanced Accessible Pedestrian System

Overview

The Advanced Accessible Pedestrian System is the latest development in pedestrian smart signal technology that provides pedestrians with customized audible and haptic feedback. Each button has a locator tone to assist pedestrians in finding the button. When the pedestrian registers a call, audio and vibrotactile guidance is initiated and updated concurrently with the status of the walk signal visual display.

Web-based Management

The AAPS is the first of its kind to use web-based management, which enables traffic agency technicians to update and monitor the system remotely over network communication lines via traditional workstations, laptops or any device that is web browser compatible.

Operators can view AAPS systems in real time and control audio and visual components with the capability to download files directly to individual pedestrian stations or to an entire network. Other features include ambient gain compensation, detectable sound, groupings, and night mode offering smart sound control.

Advanced Pedestrian Controller (APC)

The Advanced Pedestrian Controller (APC) interfaces with the traffic control cabinet and provides a single point for configuration and status information. The front panel displays Advanced Pedestrian Buttons (APB) status and provides for all connections. Secure remote access is available to the APC when the cabinet is on a network.

The AAPS can be easily retrofitted in existing intersection controls using the preexisting pedestrian button conductors. Manufacturing by Campbell Company is done the U.S. and the system is configured at the factory for a true plug and play installation.
