Figure 6C-1. Component Parts of a Temporary Traffic Control Zone

This image illustrates the component parts of a temporary traffic control (TTC) zone.

The diagram shows the set up for a temporary traffic control zone for a two-lane roadway where both lanes are traveling in the same direction and are separated along the length of the image by a broken white pavement marking line. Arrows denoting direction of travel are shown in each lane pointing upward. Left and right shoulders shown to the outside of the two travel lanes. The left lane is shown with a solid yellow pavement marking line along the left side of the lane, separating it from the left shoulder, that runs the full length of the figure. The right lane is shown with a solid white edge line pavement marking separating the right shoulder from the right lane. The white line bows out to the left, toward the broken center line that divides the two lanes, delineating the outline of the TTC zone. To the immediate right of the bowed section of white line and running parallel to it is a series of yellow channelizing devices runs. This line of channelizing devices continues upward, runing along the center line for the length of the traffic control zone area before returning, in a diagonal line, back to right shoulder at the end of the TTC zone.

Four component parts of a temporary traffic control zone are illustrated on the right side of this figure, which are described as follows:

The image legend indicates that orange squares stand for channelizing devices, arrows indicate the direction of travel, black "T" shapes represent road signs, and a rectangle with diagonal hash marks represents the work space.
