Wheelchair access is a term used to describe the ability for people in wheelchairs to access buildings, public transportation, and other areas. The term is often associated with the installation of ramps, which are structures that allow wheelchairs to move up and down inclines. The term 'RAMP' is a four-letter word that is often used in conjunction with wheelchair access. Ramps provide a safe and convenient way for people in wheelchairs to enter and exit buildings, as well as navigate public spaces.
