audit groups were analyzed. Methods used for the analysis are presented in Section 3.2,Comparative Analysis.3.1.1. Audit GroupsThe audit groups consisted of a control group, two independent engineers, and ateam of superintendents. The control group included a University of Wyoming Professor,a FHWA Traffic Safety Engineer, and a Wyoming Department of Transportation StateTraffic Engineer. The team of superintendents consisted of three road supervisorslocated in other Wyoming counties. The data collected by the different teams wereanalyzed using the control group as the basis for comparison.3.1.2. Site IdentificationThe trial audit selected local rural roads, which fit the classifications developedpreviously (see Table 3).Table 3.

The trial audit was conducted in County 1 in the southeastern part of Wyoming. Thesecond and final audit was conducted in the northwestern part of the state. Countyengineers audited their own roads and those of the other county engineer. Both countyengineers were familiar with the classification issues and also had attended an RSAspecialty workshop held in 1998. The final audit used five local rural roadclassifications. In Table 4, the additional classification of a major medium speed localrural road was added.The major local rural classification was subdivided to reflect the different safetyneeds that change with operating speed. The difference in access frequency was a majordetermining characteristic of these two major local rural road classifications.Table 4.
