Figure 3B-8. Examples of Dotted Line and Channelizing Line Applications for Exit Ramp Markings (Sheet 2 of 2)
This figure illustrates three examples of dotted line and channelizing line applications for exit ramp markings, A, B, and C. The figure is composed of two sheets.
Sheet 2 of the figure shows a vertical highway, example C:
- A legend shows a black arrow indicating the direction of travel in the lanes.
- Example C, parallel deceleration lane at a multi-lane exit ramp having an optional exit lane that also carries the through route, shows the four right lanes of one direction of a divided highway. Arrows indicate that the direction of travel is from the bottom of the figure to the top. A solid yellow line is to the left of the leftmost through lanes, a solid white line separates the rightmost travel lane from the right shoulder, and the through lanes are separated from each other by a broken white line. Near the bottom of the figure, a deceleration lane is added to the right of the four through lanes, leading to a right exit ramp. The deceleration lane runs parallel to the through lanes and is separated from them by a dotted white line. Notes state: "Normal width dotted lane line or dotted extension of right-hand edge line is optional in deceleration lane taper" and "Normal width dotted white lane line from upstream end of full width deceleration lane to theoretical gore or to upstream end of optional solid white lane line." The dotted white line changes to a solid white line in advance of the theoretical gore. This solid white line is labeled as a "normal width or wide solid white lane line (variable length)." The length of this solid white line in advance of the theoretical gore varies. At the theoretical gore, the solid white line continues on the exit ramp to the physical gore. It is labeled a "normal width or wide solid white lane line." The exit lane is wide enough that the solid wide line is shown separating left and right exit lanes. On the left side of the left exit lane, white channelizing lines form a white triangle or neutral area in front of the physical gore. This triangle is shown with "optional white chevron markings in the neutral area." The exit ramp angles off to the right.
