It means that disabled/handicapped people will be able to go out and about to the same places and enjoy the same activities as the able-bodied/non-handicapped.
For example, the Americans with Disabilities Law makes it mandatory in the US that all public transportation (buses, trains, subways) be wheelchair-accessible. ATM machines, elevators, and other such devices have instructions printed in Braille. Walk/Don't Walk crossings at very busy intersections have audible chirps and buzzers to alert the blind that the light is green. Public buildings have wheelchair ramps. Television sets have built-in closed captioning ability. A certain percentage of rooms in each hotel must be equipped with handicapped-accessible shower stalls. Etc, etc.
