Figure 2E-40. Examples of Regulatory Signing and Pavement Markings
at Entrance Ramp Terminal Where Design Does Not Clearly Indicate
the Direction of Flow
This figure illustrates examples of regulatory signing and pavement
markings at an entrance ramp terminal where the design does not
clearly indicate the direction of flow.
The figure shows a horizontal four-lane divided highway. Arrows
show that the direction of travel is two lanes of traffic in each
direction.
A solid yellow line separates the leftmost lane of each direction
of travel and the travel lane of the entrance ramp from the adjacent
(left) shoulder. A broken white line separates the two lanes of
each directional roadway. A solid white line separates the rightmost
lane of each direction of travel and the travel lane of the entrance
ramp from the adjacent (right) shoulder.
At the bottom left of the eastbound roadway, an entrance ramp is
shown intersecting and merging with the roadway at about a 45-degree
angle. On the right side of the entrance ramp where it joins the
roadway, two signs are shown: (1) a square white sign with a left-pointing
right-angle arrow with a diagonal red slash across it, facing the
traffic on the entrance ramp, and (2) a horizontal rectangular sign
with a white horizontal left-pointing arrow on which the words "ONE
WAY" are superimposed, with the sign face shown parallel to
the direction of travel on the entrance ramp. A white wrong-way
arrow is shown on the pavement between these two signs.
On the median between the two sections of the roadway, a horizontal
rectangular black sign is shown with the words "ONE WAY"
in black on a white arrow pointing to the right. It is shown placed
opposite the point where the entrance ramp joins the roadway and
is shown with the face of the sign parallel to the roadway. On the
eastbound roadway, a white wrong-way arrow is shown on the pavement
in each lane where the entrance ramp joins the highway.
A legend shows a black arrow indicating the direction of travel
on the highway and an outline arrow to show a wrong-way arrow that
is denoted as "(OPTIONAL)."
