Development of Mobile Accessible Pedestrian Signals (MAPS) for Blind Pedestrians at Signalized Intersections

The University of Minnesota’s Center for Transportation Studies has released a report that explores the development of the mobile accessible pedestrian signals (MAPS) prototype that is designed to help support decision making by blind pedestrians at signalized intersections.
The MAPS system integrates Smartphone, Wi-Fi, Bluetooth, and traffic signal controller technologies to provide signal phasing and timing, and intersection geometry information to pedestrians at signalized intersections.
