Public Space Design Considerations For Individuals Who Are Blind Or Vision Impaired Multimodal and Public Space Design Guidelines August 17, 2011
People Who are Blind Use • Long Cane or White Cane • Human Guide • Dog Guide
Detecting Environment • HEARING – immediate & distant • LONG CANE – immediate environment • Textures - grass, gravel, sidewalk • Drop-offs - curbs & holes • Tip of cane drops over curb - angle of the cane changes • Step-ups – curbs & stairs • Obstacles - poles and trees • Side of cane encounters an object.
Analyze Intersection • Traffic – occasional, medium, heavy • Speed of traffic • Lanes of traffic - 1, 2, 3, etc. • Intersections – “T”, “+”, “Y”, “X”, other • Traffic control - none, stop, yield, traffic light • Is the traffic control regular or inconsistent?
Crossing Streets • Parallel and Perpendicular streets • Square off with (face) street you wish to cross; the “perpendicular” street. • Listens for the traffic on the “perpendicular” street to stop • Immediately begins to walk when the traffic in the “parallel” street begins to move.
Problems Encountered • Quiet Cars • Roundabouts • Accessible Pedestrian Signals • Time To Cross Traffic Light Intersections • Curb Ramps • Right Turn on RED
Quiet Cars While this group cannot directly affect this issue with public space design, we should be aware of the issue.
Roundabouts • Hazard to individuals who are visually impaired AND those who are not visually impaired. • One solution - install traffic lights that could be activated when someone wants to cross, otherwise the traffic light remains green.
Audible Pedestrian Signals • Problems include • Placement of button • Bird sounds to indicate when to cross • Are they needed at every street crossing?
Time to Cross Street • Hazard to both individuals who are visually impaired and for some of general public • Blind • Wheel chairs • Elderly
Curb Ramps • Blended curbs • Angled ramps
Resources • United States Access Board (http://www.access-board.gov/) • Accessible Pedestrian Signals • Pedestrian Access to Modern Roundabouts • Roundabout Signalization to Provide Pedestrian Access • Visual Detection of Detectable Warning Materials • Accessible Pedestrian Signals (http://www.apsguide.org/index.cfm)
