Human Factors: Optimizing Crosswalks and Aesthetic Surface Treatments (a.k.a. Pavement Art) for Pedestrians with Disabilities

Project Summary

This research looks to establish guidance and technical specifications that complement MUTCD standards and better ensure that aesthetic surface treatments support pedestrians with visual disabilities. The goal is to establish best practices and guidance for the use of aesthetic crosswalks or pavement art to enhance safer and more efficient use of crosswalks by pedestrians with visual impairments (low vision) and safer vehicle-pedestrian interactions. The project examines naturalistic use of newly implemented aesthetic crosswalks and conducts controlled experimental studies to determine visual features that are most critical for accurate detection and efficient use of aesthetic crosswalks by all pedestrians, and particularly among those with visual impairments (low vision). The use of research survey, naturalistic, and experimental methods allows for a broad and in-depth assessment of the interaction between individuals with low vision and aesthetic crosswalk markings.
