Channelization is atraffic engineering concept that employs the use of secondary roads orslip lanes to separate certain flows of traffic from the main traffic lanes. The method came into favor in theUnited States in the 1950s. One of the most effective and efficient methods of controlling the traffic on a highway is the adoption of highintersection geometric design standards.
Channelization is an integral part ofat-grade intersections to separate turning movements from through movements that are considered advisable. That helps greatly to reduce the intensity and frequency of loss of life and property fromcrashes. Proper channelization increases capacity, improves safety, provides maximum convenience, and instils driver confidence. Improper channelization has the opposite effects and may be worse than none at all.
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 ofpavement markings, raised islands, or other suitable means to facilitate the safe and orderly movement of both vehicles andpedestrians.
A turn island may be created where turns are channelized to reduce stop line distance, reduce pedestrian crossing length, and facilitate traffic movement in the turning direction.[1]
