Overview

Product Overview

The WiAAPS is an Accessible Pedestrian System (APS) based on network communications. Communication from the traffic controller cabinet to the pedestrian station is done wirelessly. Power for the pedestrian stations can be provided via 2 wires running from the Advanced Pedestrian Coordinator (APC), which resides in the cabinet, or from an alternate source (solar powered or PedSafety’s Signal Power Interface (SPI). In many cases, the two conductors for power are already at the intersection from the previous pedestrian detector system.

The WiAAPS uses a web browser-based interface to manage and monitor the system. This web browser can be viewed on any device with a network connection to the APC. Desktop computers, laptops, and even handheld devices can connect and operate the system as long as they share a network connection.

The WiAAPS provides all of the standard features for an APS as defined by the MUTCD as well as additional features based on local specifications. A locator tone tells a pedestrian that the crossing is equipped with APS and where it can be found. An extended press provides specific crossing information and access to additional functions. The audible walk tone or message is accompanied by a vibro-tactile indication during the visual walk display. Optional clearance phase indications may provide additional information to the pedestrian where appropriate.

Each WiAAPS is pre-configured at the factory based on the documentation provided by the customer. Configuring the WiAAPS can be done entirely through the APC management webpage, so the customer can re-configure the system as needed. In addition, audio files and operating firmware can be updated directly on an APB through a USB connection.

Components

There are three primary components to the WiAAPS; the WiAPC, a Termination Board, and one or more Wireless Advanced Pedestrian Buttons (WiAPB).

The WiAPC is the center point of the WiAAPS. It provides both power and pedestrian signal information to all of the WiAPBs. The WiAPC is also the point at which the system is configured. The WiAPC is installed in the traffic controller cabinet. It connects to the 120VAC load switch outputs for the pedestrian signals and the low voltage pedestrian call inputs.

The termination board is installed in the traffic controller cabinet with the WiAPC. It provides a convenient place to land all the power connections to the WiAPBs. The termination board also provides current-limiting protection to each field connection. If alternate power is provided to the WiAPBs, the termination board is not required.

The WiAPB is the point of interaction with the pedestrian.

WiAPB “Wave”

The WiAPB “Wave” feature provides pedestrians a secondary, no-contact form of actuation that protects against the spread of germs and viruses. The WiAPB “Wave” uses active infrared to detect the presence of a pedestrian’s hand typically 1 – 6 inches away from the device. This distance can be adjusted to increase the detection range to typically 1 – 9 inches or decrease the detection range to typically 1 – 3 inches from the device. The “Wave” sensor detection sensitivity can be adjusted so the device actuates with slower or faster hand movements.

The “Wave” sensor works independently from the physical piezo driven push button on the APB and can be turned off if requested. The “Wave” sensor can detect various materials and skin tones to provide a non-exclusive form of actuation for all pedestrians. The sensor resides directly below the physical piezo push button.

Contact PedSafety Tech Support at 208-345-7459 option 2 if the sensor settings need to be changed.

Audio Messages

The WiAAPS comes fully programmed with audio files from the factory but we give you the option to create your own custom messages in a simple .wav format that can be easily uploaded
via the APC network connection. Second languages, gender narrative, and special percussive tones can be easily created, uploaded, and saved via System Configuration.

Accessing the Utility

To make changes and view the WiAAPS utility, simply plug an Ethernet cable into the Ethernet port on the front of the APC. Then connect the Ethernet cable into your laptop. Launch a web browser such as Google Chrome and type in the APC IP address into the
address bar. (See Below)

Status Tab

The Pedestrian Signal Status shows the current state of the system configuration and the status of each of the connected APBs.

APC Settings

This tab is where the APC configuration is set, including intersection information

Active Stations – allows for a station to be set to active (On) or non-active (Off)

Intersection Identification
The intersection identification can be found here:

• Location:
• Intersection:
• CC#
• PO #
• An Intersection image can be selected here and then click “Submit Intersection Identification” to update APC

The APC can be set to normal operation (120V I/O Mode) or test (Simulator Mode). The simulator mode allows for the APC and APBs to be tested without being connected to the traffic controller.

Station Settings Tab

Setting station IDs and individual station configuration is done on this tab.

Station ID – allows for the stations to be assigned a specific station ID by using the station’s MAC address, or change which station is assigned to a specific station ID. Utilizing the Station Identity function allows for the station to audibly identify its assigned station ID.

Please consult PedSafety Technical Support prior to using the Reboot, Bootloader or Reset Radio functionality.

All active stations will be shown in this tab. The following settings can be changed:

• Phase and Sync Call

• Station Mode

  • MUTCD – allows the Stations to perform the assigned functions in accordance with MUTCD and the configuration created (utilized while in operation at the intersection)
  • SET ID Mode – allows the stations to accept the setting or changing of the station’s ID
  • Audio Mode – allows the stations to accept the setting or changing of the stations audio files

• Station Walk Timeout

• Station Button Time

  • Extended Press Time: Time in (ms) the contacts will closed to the traffic controller to signify an extended press was made.
