engineers audited <strong>the</strong>ir own roads and those of <strong>the</strong> o<strong>the</strong>r county engineer. The county engineerswere familiar with <strong>the</strong> classification issues and both also had attended an RSA specialtyworkshop held in 1998. When all <strong>the</strong> appropriate data were collected, a comparative analysiswas conducted using percentage and weighted percentage of agreement to identify <strong>the</strong> differenteffects of auditor skill and urgency of improvement identifications.ResultsThe percent of agreement analysis indicated that <strong>the</strong> combined decisions of <strong>the</strong> twoengineers (hypo<strong>the</strong>tical team) identified <strong>the</strong> largest number of safety issues that also wereidentified by <strong>the</strong> control group. In <strong>the</strong> first field audit, all groups had a closer agreement <strong>for</strong> <strong>the</strong>higher roadway classifications (local rural major and minor subclasses). In <strong>the</strong> second fieldaudit, <strong>the</strong> closest results were obtained <strong>for</strong> <strong>the</strong> rural major medium-speed and rural minor roadclassifications. The results were specifically close in <strong>the</strong> evaluation of roadside features, roadsurface, and intersections and approaches categories of safety needs. Contained in <strong>the</strong> ExecutiveSummary attachment is a “Look For” list of <strong>the</strong> subcategories of safety issues. This attachmentalso contains <strong>the</strong> recommended complete RSAR process <strong>for</strong> rural local governments. The nextstep is to implement improvements that address <strong>the</strong> results of <strong>the</strong> RSAR. To accomplish thisobjective, a short factual proactive report is a potentially needed tool to secure funding and tohelp <strong>the</strong> county transportation agency. A sample of such a report is contained in <strong>the</strong> ExecutiveSummary attachment. The final step is to learn from <strong>the</strong>se improvements by evaluating <strong>the</strong>ireffectiveness over time.The weighted percent of agreement analysis used only <strong>the</strong> highest safety severity issues.In <strong>the</strong> first county, results of <strong>the</strong> engineers considered as a team were close to matching <strong>the</strong>13
