A curb cut (US) or dropped kerb (UK) is a ramp leading smoothly down from a sidewalk to an intersecting street, rather than abruptly ending with a curb and dropping roughly 10-15 cm (4~6 inches).
This feature allows someone in a wheelchair, on a toddler's tricycle etc., to move onto or off of a sidewalk without difficulty. A pedestrian using a walker or cane, pushing a stroller or buggy, pushing or pulling a cart or walking next to a bicycle also benefits from a curb cut.
It can also be used by someone on a bicycle, roller skates, skateboard, etc. For the safety and comfort of pedestrians this may be a disadvantage.
In the United States, the Americans with Disabilities Act (ADA) requires that curb cuts be present on sidewalks. Supporters of the ADA often point to curb cuts as an outcome of the ADA that benefits every user of public resources, even though the law is meant to protect the rights of people with disabilities.
The first curb cuts in the United States were pioneered in Berkeley, California, in 1970, according to a commemorative plaque there.
A curbcut (U.S. dropped kerb (UK), or pram ramp (Australia) is a ramp leading smoothly down from a sidewalk to a street, rather than abruptly ending with a curb and dropping roughly 4–6 inches (10–15 cm).
Curbcuts placed at street intersections allow someone in a wheelchair, on a toddler'stricycle etc., to move onto or off a sidewalk without difficulty.
A wider curbcut is also useful for motor vehicles to enter a driveway or parking lot on the other side of a sidewalk.
This driveway and curbcut policy was developed to establish and standardize a policy to regulate, and control the location, size, spacing, type, width, alignment, construction, quantity of driveway accesses, sidewalk driveway crossings, and the design of driveway access on public streets servicing adjacent private properties.
The definition of a driveway apron is the area, construction or improvement between the curbcut or proposed curb line and the back edge of walk line, to provide ingress and egress for vehicles from the alley, street, or roadway to a definite area of the private property.
Curbcut is the total street curbing that is removed to place a driveway and slopes (transitions).
