• Abstract:
  The objective of this project was to evaluate and produce uniform recommendations for Advisory Exit and Ramp Speed signs (W13-2 and W13-3) and Combination Horizontal Alignment/Advisory Exit and Ramp Speed signs (W13-6 and W13-7), including basis for speed designation, use of “Exit” versus “Ramp,” effects of sign placement, and optimization of sign sequence. The research team used a three-phase approach, which included a literature and state-of-practice review, a laboratory comprehension study, and a field study. Additional signs, such as Horizontal Alignment Warning signs with Advisory Speed plaques, that are commonly used in conjunction with Advisory Exit and Ramp Speed signs were also evaluated.
