What is APS? • Accessible Pedestrian Systems - are enhancements to the traffic signal system to provide signal phase information in non-visual formats such as: audio, tactile, and vibrotactile. 4/29/2015 Pedsafety.com 3

What ADA Requires? Federal Register Vol. 59, No. 117 14.2.5 Crossing Controls Requirements for control button size, operating force, mounting height, and location. • Button diameter of 2 inches • Maximum Force required for operation 5 lbf (22.2 N) • Maximum height of 42 inches above the sidewalk. • 30 inch by 48 inch level area within 10 inches horizontally of the button. 4/29/2015 Pedsafety.com 4

Made in USA • Assembly of APS -Boise ID • Circuit boards – Boise ID • Powder Coating -Boise ID • Signs Screen Printed -Boise ID • Engineering -Boise ID • American Aluminum • HAAS machines built in USA 4/29/2015 Pedsafety.com 5

MUTCD 2009: Pedestrian Detectors and APS Section 4E.08: Pedestrian Detectors Section 4E.09: Accessible Pedestrian Signals and Detectors – General Section 4E.10: Accessible Pedestrian Signals and Detectors – Location Section 4E.11: Accessible Pedestrian Signals and Detectors – Walk Indications Section 4E.12: Accessible Pedestrian Signals and Detectors – Tactile Arrows and Locator Tones Section 4E.13: Accessible Pedestrian Signals and Detectors – Extended Pushbutton Press Features 4/29/2015 Pedsafety.com 6

Understanding APS • Locator tone - 0.15 seconds or less (4E.12) • Acknowledgement message – “Wait” (4E.11) • Location Message – “Wait to Cross Main @ 1 st ” (4E.13) • Walk message – Vibrotactile “Percussive / Walk sign is on to cross 1 st ” (4E.11) • Beaconing (4E.11) 4/29/2015 Pedsafety.com 7

When to Install APS • PROWAG - Proposed Right-of-Way Accessibility Guidelines (DRAFT) – All new intersections will require APS (R209.1) – For existing signals APS will be added if the signal controller and software are altered, or signal head is replaced. (R209.2) – http://www.access-board.gov/attachments/article/743/nprm.pdf • Or if a vision impaired pedestrian requests APS • MUTCD Sets guideline of how to install 4/29/2015 Pedsafety.com 8

Designing APS Installations MUTCD 4E.11-13 : • Verbal messaging when less than 10 feet of separation between stations (4E.11) • Percussive tones shall be used when there is greater than 10 feet of separation (4E.11) • Tactile Arrow pointed in the direction of the crosswalk (4E.12) 4/29/2015 Pedsafety.com 9

Less than Ten Feet Separation Verbal message shall be used (4E.10) 4/29/2015 Pedsafety.com 10

Greater than Ten Feet Separation Percussive tone shall be used (4E.11) 4/29/2015 Pedsafety.com 11

When (some) stations are less than 10 ft • In the event that some of the audible pedestrian stations are less than 10’ apart • The stations that are less than 10’ must have verbal messages. • Having mixed messages in an intersection can cause some confusion. 4/29/2015 Pedsafety.com 12

Operational Check • Momentary press – Acknowledgement (Default Mode) • Extended Press – Location message/Beaconing – EP APS Mode • LED (latching) • Walk Message – Verbal or Percussive 4/29/2015 Pedsafety.com 13

When to Implement Beaconing • Greater than 70’ crossing • Skewed or irregular crossing • Visually impaired person requests • Engineering study shall be conducted 4/29/2015 Pedsafety.com 14

Features • Night mode – Locator tone set to be heard 6-12 feet from station or building line (whatever is less) – At night this can be lower for residential areas – Cannot disable locator by time of day • Ambient Gain Compensation-AGC – The volume will rise and fall with the ambient noise. (4E.11) 4/29/2015 Pedsafety.com 15

Building line • Locator tone must not be heard at the building (4E.12) • Candidate for Constant Locator tone (no AGC) 4/29/2015 Pedsafety.com 16

Echo and Absorption of Sound • Buildings (downtown) Echo Hard Surface • Alleys • Garages Soft surfaces will absorb sound • Trees, Bushes and Grass 4/29/2015 Pedsafety.com 17

Sound vs Distance Formula • The sound level will decrease by 6 dB every time the source to the listener's distance is doubled. • Half the SPL (Sound pressure level) 4/29/2015 Pedsafety.com 18

Benefits of APS • Visually impaired pedestrians navigate by audible information and by touch. The raised tactile arrow gives them a direction and audible walk message /vibrotactile gives the information that the Walk sign is on. • Visually impaired peds have a hard time navigating intersections with electric vehicles. • Texting Pedestrians 4/29/2015 Pedsafety.com 22
