AIM:
AS AN ARCHITECT OUR RESPONSIBILITY IS TO INTEGRATE DISABLE PEOPLE
INTO SOCIETY IN ORDER FOR THEM TO TAKE AN ACTIVE PART IN SOCIETY
AND LEAD A NORMAL LIFE. TO BE ACTIVE, A DISABLE PERSON SHOULD BE
ABLE TO COMMUTE BETWEEN HOME, WORK AND OTHER DESTINATIONS.
THE TECHNICAL AIM OF THE PRESENTATION IS TO PROVIDE A BARRIER-
FREE ENVIRONMENT FOR THE INDEPENDENCE, CONVENIENCE AND
SAFETY OF ALL PEOPLE WITH DISABILITY.
IN PHYSICAL TERMS, THE PROVISION OF A BARRIER-FREE ENVIRONMENT
CAN BE UNDERSTAND IN FOUR COMPLEMENTARY DOMAINS:
INSIDE BUILDING
IN THE IMMEDIATE VICINITY OF BUILDINGS
ON LOCAL ROADS AND PATHS.
IN OPEN AREA AND RECREATIONAL AREAS.

PATHWAYS:
A FOOTWAY, OR PAVEMENT, IS THE PEDESTRIAN PORTION OF
A HIGHWAY ADJACENT TO, OR CONTIGUOUS WITH, THE
CARRIAGEWAY. A FOOTPATH IS THE PEDESTRIAN PORTION OF
A HIGHWAY THAT HAS NO CONTIGUOUS CARRIAGEWAY
ASSOCIATED WITH IT.

The minimum width of an unobstructed pathway should be 0.90 m.
The minimum width of a two-way wheelchair traffic passage is 1.50
m. The preferable width is 1.80 m
ON A GUIDE STRIP WHERE ALTERNATIVE ROUTES EXIST
OR AT A JUNCTION OF GUIDE STRIPS
AT A PEDESTRIAN CROSSING
AROUND OBSTRUCTIONS WHICH ARE DIFFICULT FOR
THE SIGHTLESS TO DETECT.
A TACTILE GUIDING AREA, PREFERABLY OF RUBBER
TILES WITH MINIMUM DIMENSIONS OF 0.90 M X 0.90 M,
SHOULD BE CONSTRUCTED IN A GUIDE STRIP AT CROSS
PATHWAYS WHERE THE ROUTE BRANCHES OFF IN
SEVERAL DIRECTIONS.

1 8 JAN,2009

CURB RAMPS:
WHERE THE FOOTWAY IS NEW OR BEING TOTALLY
RECONSTRUCTED THE RAMP PROVIDED SHOULD
EXTEND OVER THE WHOLE WIDTH OF THE FOOTWAY
AND HAVE A MAXIMUM GRADIENT OF 1:9. A TACTILE
SURFACE SHOULD ALSO BE PROVIDED.

THE H MARKING SHOULD BE APPLIED TO ALL DROPPED CROSSINGS TO INDICATE TO MOTORISTS THAT
THERE IS A CROSSING PRESENT AND NOT TO PARK THERE.

IF A DROPPED KERB IS PROVIDED ON ONE SIDE OF THE ROAD, A DROPPED KERB MUST BE PROVIDED
AND ALIGNED ON THE OTHER SIDE AND ON ANY INTERVENING CENTRAL REFUGES.
THE MAXIMUM SLOPE OF A CURB RAMP SHOULD BE 1:12.

THE MINIMUM WIDTH OF A CURB RAMP SHOULD BE 0.90 M, EXCLUDING THE
SLOPING SIDES. THE RECOMMENDED WIDTH IS 1.20 M

1 9 JAN,2009

PEDESTRIAN CROSSINGS:
ACOUSTIC DEVICES SHOULD BE INSTALLED ON A POLE AT THE POINT OF
ORIGIN OF CROSSING AND NOT AT THE POINT OF DESTINATION.
THE INSTALLATION OF TWO ADJACENT ACOUSTIC DEVICES SUCH AS
BLEEPER'S IS NOT RECOMMENDED IN ORDER TO AVOID DISORIENTATION.
THE TIME INTERVAL ALLOWED FOR CROSSING SHOULD BE
PROGRAMMED ACCORDING TO THE SLOWEST CROSSING PERSONS.
TRAFFIC ISLANDS
THE TRAFFIC ISLAND DEPTH SHOULD NOT BE LESS THAN 1.50 M.
THE WIDTH OF A TRAFFIC ISLAND SHOULD NOT BE LESS THAN 1.50 M.
A COLORED TACTILE MARKING STRIP AT LEAST 0.60 M WIDE SHOULD MARK
THE BEGINNING AND THE END OF A TRAFFIC ISLAND, TO GUIDE PEDESTRIANS
WITH IMPAIRED VISION TO ITS LOCATION.
