Wheelmap.org is an online, worldwide map for finding and marking wheelchair accessible places, developed by the German nonprofit organisation Sozialhelden e.V. Anyone can find and add public places to the map and rate them according to a simple traffic light system. The map, which is based on OpenStreetMap, was created in 2010 by a team around social entrepreneur Raul Krauthausen to help people who use wheelchairs or wheeled walkers to plan their days more easily. Parents pushing a baby carriage can also benefit from the Wheelmap information. Currently almost 600,000 public places worldwide can be found on the map. About 300 new places are added on a daily basis. Wheelmap ist available on the website and as an app for iOS, Android and Windows Phone.
