From a safety perspective, the Ideal roadway has roadsides that are flat and unobstructed by hazards . A dear roadside area and a gradual slope allow drivers to safely recover control of a vehicle. This clear recovery area is the goal in improving roadside safety but is often cost prohibitive due to the geography of the area. In cases where it is cost prohibitive to create a fairly flat unobstructed roadside, alternative Improvements that would reduce the severity of an impact or alert a driver to a hazard can be considered such as breakaway features on posts, guardrail, rumble strips, or traffic delineators. This plan focuses on these types of Improvements for reducing fatal and serious injury collisions on county maintained roads . Prioritization Methodology WSDOT instructed the County to use the collision data, along with other pertinent roadway data the County has, to identify locations for making safety improvements . The collision data that directly links to Kittitas County's roadside characteristics shows a high percentage of fatal and serious injury collisions are occurring on roads with steep ditches, embankments and/or fixed objects in the way. These types of collisions are also occurring where there is no lighting, at non-intersection locations, on roadway curves
