BP 344 Flashcards
should be provided at walkways with changes in elevations
should be provided at pedestrian crossings and at the end of footpaths
SHOULD BE AS WIDE AS THE CROSSING OR SHOIR BE 900mm wide at minimum
Dropped Curbs
Shall be ramped towards adjoining curbs with a gradient not more than 1:12
shall be sloped towards the road with a maximum cross gradient of 1:20
the lowest point of the curb should not exceed 25mm height above the road/gutter
Dropped Curb
should only be allowed when it will not be obstruct or lessen the width of a walkway
Minimum width should be 900mm
should have a gradient not more than 1:12
CURB CUT OUTS
should be kept a level as possible and provided with slip-resistant material
minimum width is 1200mm
should have a gradient no more than 1:20 or 5% (1:100 max cross gradient)
should not have abrupt pitches in angle or interruptions by cracks that create edges above 6.5mm
Grating openings at walkaways should have max dimension of 13 x 13mm and shall not project more than 6.5mm
In lengthy walkways, wheelchair rest stops or turning spaces with minimum dimension of 1500mm should be provided
Straight forward routes with right angle turns should be observed for the blind
Walkways
Regular maintenance of the plantings adjacent to the walkways is needed to avoid overgrowth and obstruction
Passageway for the disabled should not be obstructed by furniture, bollards, etc.
Walkways
Walkway headroom shall not be less than
2 meters
should be installed at both sides of ramps and stairs and at the outer edges of dropped curbs at crossings
shall be installed at 900mm and 700mm above steps or ramps (Height at 1 or 1.06 meters if for protection at great heights)
Handrails
__________ long extension of handrail should be provided at start and end of ramps and stairs
300mm
Hand grips should be _______
30 to 50 mm wide
If attached to walls or ledges it should have a minimum clearance of 50mm from the wall or 40mm from the ledge
Handrails
give walkways defined edges either by the use of planters with dwarf walls, grass verge or similar which provides a texture different from the path. This helps the blind to determine the pathway.
Open Spaces
Directional and informational sign should be located at points conveniently seen even by a person on a wheelchair
Signage
Should be kept simple and easy to understand, should be made of contrasting colors and gray values to make detection and reading easy
Signage
On walls and doors, it should be located at max. height of 1.60 meters and a min. height of 1.40 meters
Signage
Labeling Public areas should have embossed symbols with min. height of 1mm (Braille should also be included)
Signage
To reduce the exposure time to vehicular traffic, all at grade crossing should:
- Be perpendicular to the carriageway
- Be located at the narrowest part of the road
- Have central refuges of at least 1.5 m deep and preferably 2m, where the width of road to be crossed exceeds 10m.
Crossings
Provide tactile blocks in the immediate vicinity of crossings as an aid to the blind, should be high enough to be felt but low enough to not cause tripping
brush or grooved concrete have not proved successful as tactile strips
Crossings
___________ and period or crossing distance times 0.9m/sec crossing speed, whichever is greater should be used
Light controlled crossings
Accessible parking slots should have a minimum width of ________
3.70m
Should be close as possible to building or accessible entrances and should be perpendicular or at an angle to the road or circulation areas
Parking Areas
Walkways from accessible spaces of 1.2m clear width shall be provided between front ends of parked cars
