Crossing Solutions at Roundabouts and Channelized Turn Lanes for Pedestrians with Vision Disabilities

NCHRP Report 674
Source: Transportation Research Board

This report explores concerns over the accessibility of two complex intersection forms for pedestrians who are blind: intersections with channelized right turn lanes and modern roundabouts with one-lane and two-lane approaches. Based on the findings of this research project, significant impediments to the accessibility of these sites exist for pedestrians who are blind, but some crossing solutions can increase the accessibility in terms of improving safety and reducing delay.
