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.

History and background
APS were installed at the major intersection in Newton, Massachusetts in 2001, as part of a major signalization up-grade project, and at the recommendation of the Mayor's Committee for People with Disabilities (Mayor's Committee). This is Newton's first experience with this signal type.
Process and procedure
New construction and signal up-grades
When new signals are installed in Newton, the Mayor's Committee considers whether they should have accessible pedestrian signals. Their recommendation is then referred to the departments of Public Works and Planning. For example, when signalization at an intersection is being upgraded from a flashing beacon to full signalization, input is obtained from the Mayor's Committee.
Handling individual requests
Individual requests are referred simultaneously to the Mayor's Committee and to the Traffic Council. The Traffic Council is required to respond to requests by making a decision within 12 weeks.
Consultation with local agency for the blind
The City Traffic Engineer also consults with an orientation and mobility specialist at the Carroll Center for the Blind regarding the need for APS and for suggestions regarding the most appropriate type of APS for a particular intersection.
Funding
APS in Newton were funded jointly by Public Works and Planning, with a portion of the cost being covered through the Community Development Block Grant program.
The City of Newton currently has $10,000/yr earmarked for APS.
Description of intersection
The APS were installed at a complex intersection with high pedestrian as well as vehicular traffic counts. At this intersection, three crosswalks share the same exclusive pedestrian phase timing:
- One is a mid-block arterial crossing;
- One is a minor street intersecting the arterial in a "T", near the mid-block crossing;
- The other is across a third street that enters the arterial diagonally, close to the "T" intersection of the minor street.
Because of abundant turning traffic during all vehicular phases, there
is no safe crossing time for pedestrians except during the exclusive pedestrian phase.
APS type and features
Pushbutton-integrated APS manufactured by Bob Panich Consultancy.
APS Features:
- WALK indication - audible rapidly repeating tones
- Vibrotactile WALK indication
- Pushbutton locator tone
- Tactile arrow
- Alert tone
- Automatic volume adjustment in response to ambient sound.

APS Installation
At another intersection at which APS were installed, a stub pole was installed in order to locate the pushbutton properly for one crosswalk.

Installation issues
Installation presented no technical difficulties.
Initially the signal volume was set so loud at one location that the
WALK signal was audible from a nearby intersection, possibly leading pedestrians at that intersection to believe they had the walk interval when they did not. The volume was turned down several months after the APS were installed.
Although the basic requirement in Newton for conduit in public rights-of-way is a 36" trench, actual construction may be less than 36" depending on site conditions. It is important that such an installation be based on direct field knowledge, rather than be designed in the shop.
Maintenance
No maintenance, except for volume adjustment, has been necessary since the audio-tactile pushbuttons were installed. Weather does not seem to affect their performance, and there has been no vandalism.
Evaluation
The APS have been well-received by blind users, and there have been no objections from neighbors.
The APS are in a small business area, not close to any residences.
