APPENDIX C <br />Engineering Judgment Impacting Project Prioritization of Table 4 <br />1. Priority One -Roadside Hazard Safety Improvements <br />o Road segments were selected after each accident report was examined in great detail <br />regarding fatalities, and injuries. Although a segment may have scored high due to accidents, <br />the cause of the accident may not have been road related. This initiated the thought of <br />steering away from corridor wide improvements which suggested mitigating roadway <br />locations that meet current safety standards. Following this, County wide spot safety <br />improvements were identified along these roadway segments to improve locations that <br />would benefit most from safety countermeasures. All segments that were identified as <br />needing guardrail, signs and/or delineation were then grouped together in this project <br />regardless of total score for contracting efficiency. <br />2. Priority Two -Bride Rail -Code 3 <br />o Bridges and/or structures with no rail or timber rail were classified as Code 3. Phases are <br />identified by maintenance districts. Some districts had less bridge rail to update and were <br />then grouped with adjacent maintenance districts. <br />3. Priority Three -Clear Zone Inventory <br />o Data collected and analyzed will allow for more efficient project identification in future <br />safety plans. <br />4. Priority Four -Denmark Rd <br />o The first segment of Denmark Rd MP 0.5 to MP 3.08 scores below a 60 based on our scoring <br />criteria. However this segment does have 4 bridges/structures that have deficient rail, this <br />influenced our decision to include it in the safety plan, and group it with the segment scoring <br />95 from MP 3.08 to MP 4.35. The segment scoring 95 has a curve that needs safety <br />improvements and contains accident history. By doing this we facilitate a project that would <br />provide safety countermeasure to the entire Denmark Rd corridor. <br />5. Priority five-Huntzineer Rd <br />o Phases identified by milepost instead of total score because all phases are priority 5. <br />Milepost conscious phases allow the county to continue heading south along the corridor <br />following the completion of our safety improvement project in 2017. <br />6. Priority Six -Bridge Rail -Code 2 <br />o Bridges and/or structures with no approaches or non-crashworthy railing were classified as <br />Code 2. Phases are identified by maintenance districts. Some districts had less bridge rail to <br />update and were then grouped with adjacent maintenance districts. <br />7. Priority Seven-Bridee Rail -Code 1 <br />o Bridges and/or structures with rail that does not meet current standards were classified as <br />Code 1. Following the phase identification process as Priority Two and Priority Six, phases <br />are by maintenance district to create more manageable projects. <br />8. Priority Eight -Corridor and Intersection Safety Improvements <br />o Vantage Hwy has a segment with a High score of 165, when accident reports were analyzed <br />it was identified that accidents were occurring due to motorists failing to yield to oncoming <br />traffic, exceeding safe speeds and/or weather conditions. The location of these accidents <br />did not indicate a safety issue with the roadway itself, nor did they suggest that safety <br />countermeasures should be deployed. This resulted in the decision to place it as a lower <br />priority. No. 6 Rd although containing a score of 50 which is below our stated cutoff of 60 <br />was Included due to the accidents associated with Vantage highway in the vicinity of said <br />intersection. Kittitas Highway was moved down in priority due to safety improvements <br />recently constructed throughout the corridor. Monitoring of this corridor will continue to <br />track the success of the recently constructed counter measures. <br />32 <br />
