Local Road Safety Plan Methodology : Provide a description of you r local road safety plan development/prioritization process . Describe what crash types/factors were prioritized , what risk factors were considered , how many "stars" are available for any individual road segment or intersection based on those risk factors, and what your priOritization process is between different countermeasures (based on cost, crash type addressed , etc.). The Kittitas County Road Safety Plan was developed by determining the types of crashes tha t occur disproportionately in our county as compared to all counties in the state and all public roads in the state. Analysis was performed to reveal where crashes are occurring and other factors that could contribute to crashes including the roadway characteristics, time of day, and type of vehicle. Data used for this evaluation was prov ided by Washington State Department of Transportation (WSDOT). The data was from four years of detailed information about crashes on Kittitas County roads (2008 through 2012). The collision data showed that fatal and serious injury collisions occur at a disproportionately higher rate on county roads than on all public roads in Washington State. Therefore, this Safety Plan focuses on reducing potential fatal and serious injury collisions in Kittitas County . The cause of fatal and serious injury collisions in Kittitas County is typically due to "hitting a fixed object" and "overturning ." Fatal and serious injury collis ions are also occurring under at le ast one of the following types of conditions : dark or dusk lighting, at non -Intersection locatio ns, on roadway curves (horizontal curve), exceeding sale speed, crOSSing over the centerline , vehicl e type of motorcycle , and on road s with 50 mph sp eed limits. The County's road log al so sh owe d a high frequency of fatal an d s.erio us injury collis ions on road s that are paved, have a pavement width of 26' or less, and have an Average Daily Traffic (ADT) volume of 175 or more . Due to the rural nature of our county, almost all Kittitas County roads fall under the category "no lighting,· so this characteristic was not evaluated further. Additionally, most of the roads have a pavement width of 26' or less , so the evaluation considered on ly roa ds that are 24' or less in width to focu s on the narrowest roads for safety improvements . The "motorcycle " category was not evBl uated further becau se it is not a road characteri stic. In order to have the greatest potential impact in reducing collisions, the County considered roads for evaluation and prioritization for safety improvements with the following characteristics: •. Paved (ACP, HMA, or BST). • Pavement width of 24' or less . • ADT of 175 or more . • Posted speeds of 35 or more. • Collision at this site in the past 4 years . • Roads that have been previously identified in the County's hazard elimination plan . The county road segments with the cha racteristi cs listed above wer e prio ritiz ed using contribUting factors identified from the colli sion data.
