CAG Position Statement - Accessible Pedestrian Signals
Accessible Pedestrian Signals (APS) are devices installed at signalized intersections that provide auditory, tactile and visual information of when the walk phase is on and enables people who are blind, partially sighted, or deafblind to independently navigate the crosswalk. APS must be installed at all signalized pedestrian crossings in a consistent manner, providing equitable access to the built environment for pedestrians who are blind or have low vision.

Position Statement on Accessible Pedestrian Signals
Revised – May 30, 2023
About the Consumer Access Group (CAG)
The Consumer Access Group (CAG) is a coalition of blindness related not for profit organizations. Each partner contributes their expertise to developing position statements on blindness related concerns. These statements enable organizations and individuals to advocate with a common voice on blindness-related issues, increasing the capacity of each to more effectively promote social inclusion for Canadians who are blind, deafblind and partially sighted.
Issue
Across Canada, the operation and features of accessible pedestrian signals (APS) are far from standardized. In order to enhance the safety and independence of Canadians who are blind, deafblind, or partially sighted (hereafter referred to as blind), as well as to ensure consistency that is easily recognized by pedestrians who rely on APS systems across the country, accessible pedestrian signals require agreed upon operating standards.
Background
Pedestrians who are blind cannot always determine when it
is legal to cross streets without audible and/or vibrotactile indications that
coincide with the visual traffic signals available to sighted pedestrians. APS provide non-visual indications to blind
pedestrians to know when the walk signal is in their favour. These non-visual signals can also provide directional
guidance that can assist in the crossing of non-perpendicular intersections and
multi-lane crossings. APS provide audible and vibrotactile indications that
confirm when it is legal to make a street crossing not only for pedestrians who
are blind, but also for many other users who may benefit from non-visual
prompts, such as children, seniors, and people with cognitive disabilities.
In the United Nations Convention on the Rights of Persons
with Disabilities, Article 9 states, in part, that “States Parties shall take
appropriate measures to ensure to persons with disabilities access, on an equal
basis with others, to the physical environment… open or provided to the public,
both in urban and in rural areas.”[1] Part of what it takes to
provide equal access to the physical environment is the installation of APS.
In May 2008, an APS
Committee consisting of Canadian consumer representatives, orientation and
mobility instructors, and traffic engineers submitted a set of recommendations
to the Transportation Association of Canada and culminated in the release of
the “Guidelines
for Understanding, Use, and Implementation of Accessible Pedestrian Signals”.[2]
The guidelines, while comprehensive in some areas, leave room for the discretion of deploying agencies that has resulted in a wide variety of APS operations across Canada. These inconsistencies are confusing and ultimately dangerous to pedestrians who are blind. The goal of the following recommendations is to promote consistency from one jurisdiction to another. See also Clearing Our Path.
Recommendations
All intersections with traffic control signals must be equipped with APS that meet the following criteria.
1.
Acoustic Locator
An acoustic locator
tone should be used to indicate the presence of an APS and its push button. The
tone should be audible at no more than 3.7 meters from the push button or from
the nearest building line, whichever is closer. The tone should sound for no
longer than 0.15 seconds and repeat no more than every 1.5 seconds. The sound
should be 30 to 90 decibels, automatically adjusted to be 2 to 5 decibels
louder than ambient sounds. The pitch
should be at a level that is easily identifiable by a trained user.
2.
Activation
APS should be activated
automatically, manually, or through a wireless accessible pedestrian system.
Automatic activation should be used for traffic signals that automatically
cycle between walk and don’t walk. Where manual activation is employed,
activation should only require a single press. Visual, audible, and
vibrotactile confirmation of a successful activation should be provided.
When an APS has already
been activated, it should not acknowledge a new activation but should instead
complete the cycle.
3.
Accessibility
There must be a high
contrast ratio between the pole and the pushbutton. The pushbutton should be
raised and should have a diameter of 50 millimeters. Access to the pushbutton
must be clear of obstacles and snow accumulation so that the pushbutton is
always accessible to all pedestrians.
Touchless
activation using proximity sensors may replace the button but the other
features should be present.
When
the pushbutton is pressed and held for 1.5 seconds, enhanced features will be
activated in addition to the visual, audible, and vibrotactile features. There should be a tactile, high-contrast
arrow parallel to the path of travel, tactile crosswalk mapping, and a cardinal
direction guide. Names of the intersecting streets must be provided in
uncontracted braille, raised lettering, and verbal messaging. The name of the
parallel street must proceed the name of the street to be crossed and must be
separated by the word “crossing” (e.g., Broadway crossing Main). Audible
messages must be concise, eliminating words such as street, avenue, or drive,
unless these words are essential to avoid ambiguity.
At crosswalks and
intersections employing flashing amber signals, the press of an APS button
should result in a verbal announcement stating the following: “Amber lights are
now flashing. Use caution. Vehicles may not stop immediately.”
4.
Walk Indications
Until a more specific
national standard is established, the walk indication for crossings of a
north-south direction should be distinct from the walk indication for crossings
of an east-west direction, and be consistent throughout the city/region. Sounds for both directions should be clearly
differentiated from naturally occurring and other ambient sounds so that they
can be easily recognized.
5.
Crossing Time
Additional crossing
time must be considered in conditions that could delay pedestrians, such as
when a pushbutton cannot be located within 3 meters of the curb, when the
crosswalk is unusually long or complex, or when the crosswalk slope or running
grade warrant extra crossing time.
6.
Operations
Post-installation
inspections to assess sound conflicts during varied traffic conditions should
be conducted in consultation with people who are blind or partially sighted.
An APS must be operational at all times, except during repairs, maintenance, intersection or sidewalk construction, or temporary shutdowns for special events.
