Section 2C.14 - Advisory Exit and Ramp Speed Signs (W13-2 and W13-3)
Current through Register Vol. 28, No. 3, September 1, 2024
Standard:
01 Advisory Exit Speed (W13-2) and Advisory Ramp Speed (W13-3) signs (see Figure 2C-1) shall be vertical rectangles. The use of Advisory Exit Speed and Advisory Ramp Speed signs on freeway and expressway ramps shall be in accordance with the information shown in Table 2C-5.
Guidance:
02 If used, the Advisory Exit Speed sign should be installed along the deceleration lane and the advisory speed displayed should be based on an engineering study. When a Truck Rollover (W1-13) sign (see Section 2C.13) is also installed for the ramp, the advisory exit speed should be based on the truck advisory speed for the horizontal alignment using recommended engineering practices.
03 If used, the Advisory Exit Speed sign should be visible in time for the road user to decelerate and make an exiting maneuver.
Support:
04 Table 2C-4 lists recommended advance sign placement distances for deceleration to various advisory speeds.
Guidance:
05 If used, the Advisory Ramp Speed sign should be installed on the ramp to confirm the ramp advisory speed.
06 If used, Chevron Alignment (W1-8) signs and/or One-Direction Large Arrow (W1-6) signs should be installed on the outside of the exit curve as described in Sections 2C.09 and 2C.12.
Option:
07 Where there is a need to remind road users of the recommended advisory speed, a horizontal alignment warning sign with an advisory speed plaque may be installed at or beyond the beginning of the exit curve or on the outside of the curve, provided that it is apparent that the sign applies only to exiting traffic. These signs may also be used at intermediate points along the ramp, especially if the ramp curvature changes and the subsequent curves on the ramp have a different advisory speed than the initial ramp curve.
Support:
08 Figure 2C-3 shows an example of advisory speed signing for an exit ramp.
