• The number of reported crashes in the previous five years for the studied roads are <br />as follows: <br />Road Name <br />Reported Crashes <br />Westside Rd <br />6 <br />Mohar Rd <br />0 <br />Nelson Siding Rd <br />4 <br />Bullfrog Rd <br />1 <br />BACKGROUND: <br />Public Works installed traffic tubes to collect data on Westside Road, Nelson Siding <br />Road, Mohar Road, and Bullfrog Road (Exhibit 1) to collect traffic data between July 2, <br />2024, to July 10, 2024. Speed and volume data for this time period are shown as Exhibits <br />2 and 3 comparing measured data to typical data. Typical data is taken from Public <br />Works regularly collected traffic counts for all county roads representing non -holiday <br />weekday metrics. The comparison dates for Mohar, Nelson Siding, and Bullfrog come <br />weekday counts from June of 2022. The comparison date for Westside Rd comes from <br />weekday counts in September of 2022. <br />Data was not collected on Upper Peoh Road due to annual chipseal work occurring <br />around the time period. Equipment installed on Bullfrog Road was disturbed on Sunday, <br />July 7, limiting the data collection dates from July 2 to July 6. <br />There have been several [I I ] accidents reported on the study roads over the last five <br />years. Zero were reported over a holiday weekend. <br />DISCUSSION: <br />Data collected over the July 4th holiday weekend is consistent with data collected during <br />the Fehr and Peers traffic study in 2020. The traffic data collected by Fehr and Peers was <br />during the Labor Day weekend period. Both speed and volume data collected represent <br />traffic above average for these sections of road. <br />Public Works has installed speed feedback radar signs on Westside Road, Nelson Siding, <br />Upper Peoh Road, and Bullfrog Road as was recommended in the Fehr and Peers report. <br />The County has been working with SO Alliance to facilitate a feasibility study for <br />options intended to keep the traveling public on I-90 and reduce the use of County Roads <br />as bypass routes for I-90 congestion. Public Works will continue investigating potential <br />short-term solutions. <br />FISCAL IMPACT: <br />None <br />ATTACHMENTS: <br />Exhibit 1: Speed Study Results Map <br />Exhibit 2: Speed Study 85th Percentile Speed Results <br />Exhibit 3: Speed Study ADT Results <br />
