Accessible Pedestrian Signals: Morgantown, WV

Project Abstract

This case study is one of nine case studies on accessible pedestrian signals posted by Pedestrian and Bike Information Center. These studies describe experiences of US cities that have installed Accessible Pedestrian Signals. Some of these cities have a long history of installing APS; others have more recently installed APS at one or two intersections. This and each case study includes information on the municipality's history of APS installation, process and procedures, types of devices installed, dates installed, installation, maintenance, and evaluation issues, and contact information.



wv 1:  Mounting of two Prisma pushbutton units on a single pole. See arrows on insert detail for the orientation of the tactile arrow on the top of each unit. Both devices make the same sound during the Walk indication, which is acceptable in this installation since there is exclusive pedestrian phasing.

History and background APS were installed in 2002, at the request of blind citizens. These are the first APS that have been installed in the state.
Process and procedure Morgantown does not have a process or procedure for determining which intersections will be equipped with APS. Typically, all traffic signal installations in West Virginia are installed by contract under the purview of the West Virginia Division of Highways.
Funding This demonstration project was fully funded by the West Virginia Division of Highways.
Description of intersection APS were installed at two intersections in the downtown area of Morgantown that have pedestrian actuation, and exclusive pedestrian phasing with right turns on red permitted.
APS type and features Pushbutton-integrated APS manufactured by Prisma Teknik (model TS-903).
APS features:
  • WALK indication for crossing in both directions is fast repetition of the pushbutton locator tone
  • Pushbutton locator tone
  • Automatic volume adjustment in response to ambient sound
  • Tactile map of crossing

Signals are being modified to include pushbutton information messages modeled after "Wait to cross Willey St. at High St. Wait for red light for all vehicles. Right turn on red permitted."
APS Installation Two pushbuttons have been mounted on some corners so the standard single arrow can be correctly oriented in the same direction as each crosswalk. This was necessary where the two crosswalks at a corner were not at right angles to each other.
Since these locations used exclusive pedestrian phases, a right-angle, double ended arrow was installed so that a single pushbutton could be located on one corner or quadrant, controlling the WALK signal for two crossing directions. The right angle arrow will be installed where both crossings are 90 degrees from a particular quadrant.

Installation issues Wiring of the APS was little different than typical (non-APS) pushbuttons.
APS are mounted to signal uprights using two quarter-inch stainless steel screws. In the future, stainless steel bands may be placed at the top and bottom sections of APS in high-vandalism areas.
Diligence is needed in the initial design of a complete intersection, so as to correctly locate APS according to the MUTCD.
Maintenance No weather-related maintenance issues.
Cabinets and signals are well guarded against transient voltage surges, including high-speed surges that are accompanied by lighting.
To date, APS have been installed at six intersections in West Virginia. At one intersection in downtown Charleston, in a high vandalism area, three APS have been knocked off the signal upright.
Evaluation APS have performed as expected according to manufacturerï¾’s literature.
Negative comments have been received from nearby businesses about the noise level of the locator tone. The entrance to one business is less than 10 feet from the pole on which two APS are mounted.
Blind users have objected to the location of some APS units (in some cases at a distance of about 20 feet from the crosswalk).
Positive comments have been received about proactive installation of APS.
