City Council and Public Involvements Complaints from public Requests from Commission on Disability Feasibility study directed by the City Councils 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

Pre-timed & Rest-in- Walk Pedestrian Crossing Pushbutton activates accessible ped signals only. WALK interval is on recall.
