1. PROBLEM IDENTIFICATION
Long and narrow corridors creating orientation difficulties.
2. PLANNING PRINCIPLE
To provide well-dimensioned corridors to facilitate the passage and maneuvering of a
wheelchair.
3. DESIGN CONSIDERATIONS
3.1 General
 Wide corridors are useful for wheelchair
users, service equipment, high traffic areas, etc.
3.2 Width
The unobstructed width of a low-traffic
corridor should not be less than 0.90 m. This also allows maneuverability in 90 turns
(fig. 1).
The unobstructed width of a public corridor
should not be less than 1.50 m. The recommended width is 1.80 m (1)
(fig. 2).
To allow maneuverability in 180 turns, the
minimum circulation space should be as shown in figure 3.
The corridor width should allow
maneuverability through the doors located along its length (fig. 2) (fig. 4).
3.3 Obstructions
Obstacles protruding into the corridor, such
as drinking fountains or public telephones, should be placed outside the circulation path,
in alcoves or cul-de-sacs (fig. 5).
Overhanging signs and obstacles should be
mounted at least 2.00 m high (fig. 6).
3.4 Surface
Changes in surface level of more than 13 mm
should be ramped.
Floor surfaces should be non-slip and even.
Carpets should be securely fastened.
4. EXISTING CONSTRUCTIONS
Narrow corridors should be widened along
their full length if feasible; otherwise, passing areas should be located at appropriate
intervals along the corridor length.
The minimum width of the passing area should
be 1.50 m and the minimum length should be 2.40 m.
In highly restricted spaces, the height of an
obstacle or sign can be dropped to 1.95 m.
Notes:
(1) 1.50 m is the minimum width for two wheelchairs to pass each other or for one
wheelchair to make a full turn. |
