Case study — Dunedin, Florida
Date: July 2003
History and background
There are two intersections in downtown and one at Patricia Avenue and Beltrees in Dunedin where APS have been installed at the request of citizens who are blind.
The City of Dunedin was awarded the Inspired Leadership Award for 2003 from the Florida Alliance for Assistive Services and Technology (FAAST) for the APS installations.
Process and procedure
Requests for APS are received by the City of Dunedin ADA Coordinator and reviewed and recommended by the City Manager appointed ADA Committee.
APS were requested by one person who is blind and who has limited hearing in one ear as well. She consulted with an orientation and mobility specialist and requested pushbutton-integrated devices and worked with the engineer on installation details.
The intersection modifications were part of a redevelopment project.
Description of intersections
One of the intersections downtown, Douglas & Main is a fairly small square intersection of two-lane streets with a pushbutton actuated exclusive pedestrian phase.
The other intersection downtown at Broadway & Main is a more complex intersection where a very busy state road intersects with the city's Main Street.
The third intersection, at Patricia and Beltrees, is a T intersection of a minor street with very busy street with a right turn lane.
APS type and features
Pushbutton-integrated devices from Polara Engineering
- Speech WALK message:
- At Douglas and Main (with exclusive pedestrian phasing): "WALK sign is on"
- At Broadway & Main: "WALK sign is on to cross Main" or "WALK sign is on to cross Broadway"
- Vibrotactile WALK indication
- Pushbutton locator tone
- Actuation indicator — tone
- Tactile arrow
- Automatic Volume Adjustment in response to ambient sound
- Extended button press — increased the volume of the WALK indication and locator tone
Figure 9-11. Two pushbuttons are located on fluted pole at this location with exclusive pedestrian phasing. Tactile arrow of each device points in the direction of travel on the crosswalk.
Two APS were mounted on each pole.
At one crossing APS were about 15 feet back from the crosswalk location, and approximately 5 feet toward the intersection from the extension of the crosswalk lines. Volume of locator tone and WALK message was quite loud
At the Patricia and Beltrees location, APS were installed on only one crosswalk, to cross the through street, as needed and requested by the person who lived near the intersection.
Installers stated that they had difficulties with figuring out the new devices but seemed to work fine after they figured them out.
Fluted poles were used in the redesign which made it difficult to align the tactile arrow.
No maintenance issues have been reported except for need to adjust volume levels.
Installation caused complaints from patrons of a restaurant/bar on one corner with outdoor seating. Locator tone was loud enough to hear from over 30 feet away.
The woman who requested the installation was initially unhappy with some parts of the installation. Original plans included a stub pole close to the crosswalk but that was not installed at first. Even with the signal adjusted to the maximum volume, she was unable to hear the WALK indication when she was standing at the crosswalk location. A stub pole was later installed which allows a reduction in volume of the device and diminishes problems for neighbors as well.
