This report examines the performance of different types of speed-reducing treatments (or combinations of treatments) in high-speed environments. The project also considered how desired speed can be aligned with a safe, anticipated operating speed with the goal of making high-speed roads more self-explanatory.
Treatments reviewed included: treatments to support development of road hierarchies in line with the concept of self‑explaining roads; perceptual countermeasures; transverse rumble strips; vehicle activated signs; gateway treatments; route-based curve treatments; wide median centrelines; and sight distance adjustments on intersection approaches.
Based on the outcomes of this review, these treatments may merit further consideration for future Austroads research and guidance.
