What is the main purpose of channelization in a construction zone?

Channelization in a construction zone is primarily designed to safely guide motorists around a work site. This is achieved through the strategic placement of barriers, cones, signs, and other devices that create a clear pathway for vehicles, ensuring that they navigate the area safely while keeping both workers and drivers protected. Effective channelization helps to minimize confusion and reduces the risk of accidents by directing traffic flow in a predictable manner.

While alerting drivers to issues such as speeding and enhancing road aesthetics can play a role in traffic management, these are not the primary goals of channelization. Additionally, increasing traffic speed contradicts the objectives of a construction zone, where safety and caution are paramount due to the presence of potentially hazardous conditions.
