This workshop provides an overview of safety treatments and countermeasures that can be used to help reduce the frequency and severity of roadway departure crashes. One low-cost strategy is to use various treatments (signing, delineation, rumble strips, and surface friction) to help keep vehicles on the roadway. For those vehicles leaving the traveled way, it is important to reduce the potential for a crash, i.e. allow the vehicle to recover without overturning or striking fixed objects. Techniques for improving shoulders, slopes, and ditches are reviewed. Removing, relocating or redesigning features such as trees, utility poles, and drainage structures in the clear zone are also addressed. Enhancing mailbox safety is also covered. The session includes discussion of minimizing the severity of roadway departure crashes through the use of breakaway supports and shielding obstacles. The essentials of barrier design, installation, and inspection are reviewed. The session concludes with case study exercises where participants apply what they learned to address actual roadway locations.
