Blind Pedestrians and the Changing Technology and Geometry of Signalized Intersections: Safety Orientation and Independence

摘要

This study documented that blind pedestrians have considerable difficulty locating crosswalks, aligning to cross, determining the onset of the walk interval, maintaining a straight crossing path, and completing crossings before the onset of perpendicular traffic at complex signalized intersections. Revised techniques and strategies are suggested for alleviating these difficulties.
