Talking Signs

Type of APS
Receiver based

Talking Signs remote infrared audible sign receiver.

Pedhead-mounted APS units transmit speech message to a handheld receiver.

Standard features
WALK indication
  • Highly directional speech message transmitted by remote infrared light, to handheld receiver - - repeats "WALK sign" and the name of the street to be crossed
  • WAIT message during Flashing DON'T WALK or DON'T WALK - - repeats "Wait" and the name of the street to be crossed.
  • Orientation message with wider transmitter range, available to pedestrians before they reach the intersection, provides street identification, signalization and/or directional information.
Optional features
  • Additional landmark information can be included in the orientation message, as this information is received before users reach the intersection, and it does not interfere with their ability to hear or attend to traffic and signal information when they are at the crosswalk.
  • Developments in the technology and installation may include radio transmitted speech or vibratory information to alert travelers to locations where transmitters are installed. This technology, developed under the direction of the Japan National Police Agency, is compatible with the Smith-Kettlewell/Talking Signs® standard.
Installation notes

Transmitter providing signal information must be carefully positioned to provide information only within the width of the crosswalk.

  • Infinitely variable messages recorded in transmitters
  • Receivers usable for many wayfinding tasks where transmitters are installed
  • Pedestrians must know where the TS transmitters are installed, or they are unlikely to search for or use the available information
  • Pedestrians who are blind must have access to receivers

The above illustration shows how the Talking Signs infrared transmitter delivers messages to the pedestrian who is carrying a receiver.

Wide beam tells:
  • Direction of travel — "traveling east"
  • Present location — "on zero hundred block of Larkin"
  • Intersecting street — "towards Grove Street"
Narrow beam tells:
  • Crossing condition and intersecting street —
    "Wait — Grove Street"
    "WALK sign — Grove Street"
  • Safe crosswalk zone
