8.  Functional limitations


               Functional limitations are restrictions in performing fundamental physical and mental
               actions used in daily life such as mobility (physical) or memory (mental).

               9.  Gangway


               An inclined solid structure to connect a building or a vessel with a berth, with handrails
               at each side.

               10. Handrail


               Component of a stair or of a ramp or other building component that provides guidance,
               balance and support.

               11. Headroom

               Clear vertical space above one’s head, as in a vehicle or room.


               12. Interaction space


               The interaction space is the space required by a person to interact with another person,
               furniture, appliance, machine or another item.

               13. Kneeling

               When a vehicle is lowered at a boarding/disembarking location to reduce the vertical
               gap between the entry/exit point to the vehicle and the boarding platform or ground
               level.


               14. Landing

               Platform or part of a floor structure at the end of a flight of stairs or a ramp or at the
               entrance to a car lift.


               15. Light Reflectance Value (LRV)

               The proportion of visible light reflected by a surface at all wavelengths and directions
               when illuminated by a light source. LRV is also known as the luminance reflectance
               factor. The LRV is expressed on a scale of 0 to 100, with a value of 0 for pure black and
               a value of 100 for pure white.


               16. Luminance

               The amount of light emitted from a surface or source in any given direction.



                                                                                                           21
