A work zone or temporary traffic control zone generally has five sections: - Advanced warning area: Road users are informed about the upcoming work zone or incident area. - Transition area: Road users are redirected out of their normal path. Transition areas usually involve strategic use of tapers. - Buffer area: It is the unoccupied space between the transition area and the work area. It’s a place where vehicles and/or equipment are not allowed - Work area: Area where workers and equipment are located. Channelizing devices are used throughout the area to keep traffic in the non-work lane. - Termination area: Work activity ends and traffic resumes at normal speed.
