Blind and Sighted Pedestrians’ Road-Crossing Judgments at a Single-Lane Roundabout
2013
Objective:The aim of this study was to evaluate the relative risk and efficiency of road crossing experienced by blind and sighted pedestrians at a single-lane roundabout with two levels of traffic volume and at two distances from the roundabout.Background:With the rapid spread of modern roundabouts across the United States, their accessibility to blind pedestrians has become an important concern. To date, accessibility research relevant to blind pedestrians has focused on multilane roundabouts, and single-lane roundabouts have been virtually ignored.Method:Blind and sighted participants made judgments about when they would cross a single-lane roundabout with high and low traffic volumes, at exit and entry lanes, and at the actual crosswalks and at locations farther from the roundabout.Results:Relative to sighted participants, blind participants’ judgments about when to cross were more frequently risky, especially when traffic volume was high. Blind participants also were slower to make crossing judgments...
