TEST DRIVE GALLING OUT GAD SIDEWALKS

摘要

The old way to see if a sidewalk is wheelchair-friendly: Crawl around on your hands and knees to measure cracks and ramps. The new way: Peter Axelson's three-wheeled cart. (1) Axelson has used a wheelchair since 1975, and in 2008 his company, Beneficial Designs, got a grant to develop technology for assessing sidewalk compliance with the 1990 Americans with Disabilities Act. The result is Prowap (for Public Rights-of-Way Assessment Process).
