Persons with a disability must have a continuous, easy-to-identify, relatively level path, free of obstructions and hazards, to enter the building, move within it, leave it and reach its accessible facilities. The path runs from a prominent point on the lot boundary with a connection to the public street or footway straight to at least one entrance in common public use (or to a point beside it) and on to an accessible lift; where difficult terrain or an unusual site makes that impractical, vehicle access plus conspicuous directional signs to the accessible entrance is acceptable. The route is at least 1050 mm clear in width, has a firm surface, and is kept clear of anything that would stop a wheelchair or a person with a disability: projecting hazards, steps, ordinary (undropped) kerbs, steep ramps, awkward doors and the like. For the Table 2 building categories the route carries a tactile guide path as Figures 6A to 6C illustrate. The Best Practice Section covers covered routes, rest areas and seating.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
