One of the most effective and efficient methods of controlling the traffic on a highway is the adoption of high intersection geometric design standards.
That helps greatly to reduce the intensity and frequency of loss of life and property from crashes.
Proper channelization increases capacity, improves safety, provides maximum convenience, and instils driver confidence.
Over-channelization should be avoided because it could create confusion and worsen operations.
Channelization of at-grade intersections is the separation or regulation of conflicting traffic movements into definite paths of travel by the use of pavement markings, raised islands, or other suitable means to facilitate the safe and orderly movement of both vehicles and pedestrians.
