Project details

Start date: 06/2000
End date: 06/2012

Description: Studies on a broad range of mobility-related issues related to the challenges of crossing streets safely and efficiently at complex intersections, such as: access by persons with blindness to roundabout intersections; driver yielding in response to the long cane and pedestrian behavior; the design and operation of accessible pedestrian signals; differences in gaze patterns of low vision and typically sighted individuals when crossing streets auditory motion perception as it relates to traffic detection visual perception of time to contact anti-veering technology; strategies for enhancing street crossing safety at roundabout intersections, including behavioral studies of a camera-based vehicle detection system, computer modeling of pedestrian and vehicle interaction, and studies of visual behavior of low vision travelers when crossing at roundabouts; underfoot and audible cues for detecting crosswalk locations, aligning for crossing streets and maintaining line of travel while crossing; access to pedestrian signals by individuals with low vision and strategies for enhancing use of pedestrian signals by individuals with low vision; the visual and auditory perceptual processes that relate to pedestrian activity in complex traffic environments, including development of measures and technologies for auditory and vehicle arrival time and the use of these measures in studies of monocular and binocular viewing, path of travel studies, and vehicle detection in daylight and nighttime conditions and studies of electric/hybrid vehicles that produce little sound cues at low speeds.
