Question

Advantages and disadvantages of cloverleaf, straight-line, zone and spiral pattern

Answer 1

The cloverleaf's advantage is that it is a layout with loop ramps that is well suited for the intersection of two highways and can securely support left-turning operations. It's ideal for use in rural or suburban areas when space is limited.

The higher travel distance for left-turning vehicles, the weaving maneuver generated, the very short weaving length allowed, and the comparatively large right of way area required are the cloverleaf's main drawbacks.
