Universal Design standards for dropped kerb

1. DROPPED
KERB
BY –
BIMENPREET KAUR
PRERNA SHARMA

2. A dropped kerb is a ramp built on a footpath or pavement to
accommodate the change in level towards vehicular areas.
The provision of a dropped kerb is to overcome potential hazard arising from
change in level for persons with or without a disability.

3. Shall be provided at :
 pedestrian crossing
 at each end of the footpath of a private street or
access road.
 separating footpath or ramp from vehicular area

4. 800 (min ) clearance at the
back of footway
Vehicular Area
150 MAX
REQUIREMENTS
Dropped kerb shall be constructed
as follows: -
• Not less than 1200 mm in length
and 1200 mm in width;
• 2. With a clearance of at least
800 mm long at the back of the
footway;
• 3. Ramped at a gradient not
steeper than 1:12;
PLAN
150 MAX

5. • With a level difference of not
more than 15 mm with the
vehicular areas;
• Provided with a tactile warning
strip at 300 mm from the
vehicular areas;
• Provided with a tactile warning strip of the
nominal width of 600 mm at the ramp.

6. Design Considerations
• The provision of a dropped kerb is to overcome potential
hazard arising from change in level for persons with or
without a disability.
• The tactile warning strip should be provided in order to
notify the presence of traffic.
• The tactile warning strip should have luminous contrast
for the elderly and persons with visual impairment.
• Dropped kerb should have slip-resistant surface. Raised
traction strips should be avoided in order to reduce the
hazard to everyone.

7. Slip Resistance
Dropped kerb should have slip-resistant
surface with a minimum “static coefficient of
friction” of “Very Good” grading.
Luminous Contrast
Tactile warning strip should have a minimum
luminous contrast of 70% with the adjoining
surfaces.
Recommended Design Requirements

8. Conjunction with Pedestrian
Crossings
Dropped kerb should be provided where
necessary and in conjunction with pedestrian
crossings, which should include visible, audible
and tactile crossing devices with traffic lights.
