The curb-return is the curved connection of curbs where two streets come together to form an intersection. The purpose of the curb-return is to guide vehicles in turning corners and to separate vehicular traffic from pedestrian areas at intersection corners.

Corner radii directly impact vehicle turning speeds and pedestrian crossing distances. Minimizing the size of a corner radius is critical to creating compact intersections with safe turning speeds. While standard curb radii are 10–15 feet, many cities use corner radii as small as 2 feet.

CURB RETURN means the portion of a curb next to a driveway approach which includes the radius of curvature, or the ramp-type lug on commercial or industrial type pavements and …

2020年11月25日 · The Civil 3D Create Intersection Wizard can be used to quickly produce the complex corridor models, which comprise intersections, with automatically generated curb return geometry.

Most curb ramps contain a combination of the following elements: approach/pedestrian access route (PAR), ramps, flares, vertical curb faces (return curbs), landings or turning spaces, transitions between the ramp and gutter, and detectable warning surfaces.

Curb return radius should accommodate the expected amount and type of traffic and allow for safe turning speeds at intersections. Curb return radius shall be installed in accordance with Table D-1.

An alley return is that portion of the curb which begins at the BCR on the intersecting street and ends at the ECR, the intersection of the property lines of the street and alley. See Figure E 616.1B. The normal curb return radius is 5 feet for an alley intersecting a street.

Where there are substantial pedestrian movements, the minimum radius of curb return where curbs are used, or the outside edge of pavement where curbs are not used shall be 15 feet.
