Corner radius Corner radius is the curved edge where two curbs meet at a street intersection. Its size influences how vehicles turn while affecting pedestrian crossing distances.
Engineers select a corner radius based on roadway design, traffic needs, and safety considerations. Larger radii can accommodate larger vehicles, while smaller radii may shorten pedestrian crossings and help reduce turning speeds. In NYC, corner geometry is established through roadway design and reconstruction projects rather than individual property repairs.
Frequently Asked Questions About Corner radius
What is corner radius?
The curved edge where two curbs meet at a street intersection.
Why does the radius matter?
A larger radius lets larger vehicles turn more easily but lengthens the pedestrian crossing. A smaller radius shortens crossings and slows turning speeds.
Who determines the radius?
Engineers set it through roadway design and reconstruction projects, based on traffic needs and safety considerations.
Can a property owner change it?
No. Corner geometry is established through City design projects, not individual property repairs.
