Accessible Pedestrian Signal Judy Wong Senior Transportation Engineer City of Los Angeles, Department of Transportation (LADOT)
Background • Conventional intersections with two signal phases
Background(continued) • Signalized intersections with multi-phase
Background(continued) • Intersections with unusual geometry
City Council and Public Involvements • Complaints from public • Requests from Commission on Disability • Feasibility study directed by the City Council’s Transportation Committee • Study presented to City Council
What is an Accessible Pedestrian Signal (APS) ? A device that communicates information about pedestrian timing at signalized intersections to the visually impaired.
Features • Locator tone: provides info regarding existence and location of ped pushbuttons • Push button: places a call for the “WALK” signal and activates the APS • Vibro-tactile arrow: indicates the direction of travel and emits a distinguishable tone as it vibrates during “WALK” phases
Ped-actuated Pedestrian Crossing • Pushbutton activates accessible ped signal and the WALK interval
Pre-timed & Rest-in-Walk Pedestrian Crossing • Pushbutton activates accessible ped signals only. WALK interval is on recall.
Applications • Intersections adjacent to a major pedestrian traffic generator such as transit centers, municipal facilities, shopping centers, etc. • New signalized locations • Intersections with left turn phasing or multiple phasing • Intersections at light rail crossings • Locations frequently used by individuals with visual disability
Cost • $1,100 per APS unit including labor and material • $650 per regular pushbutton • A typical four-leg intersection requires 8 APS units, which amounts to $8,800 per intersection.
Conclusion • Well received by the Commission on Disability • Positive feedback from the public • Developed comprehensive application guidelines • Approached by other agencies to share experience • Explore additional features to provide more benefits
