A detailed crash analysis was completed to compare the crash rates of the study intersections with <br /> other comparable intersections throughout the state. Additionally, the intersections were reviewed to <br /> determine if the crash rates are statistically significant using the critical rate method to determine if <br /> they warrant mitigation. The results of the crash analysis are shown in Table 5. <br /> Table 5:Crash Analysis(2015-2019) <br /> Intersecting Roadway Crash Rate Statewide Average Critical Rate <br /> CSAH 64 (181st Ave) 0.09 0.35 <br /> CSAH 63 (Green Valley Rd) 0.09 0.35 <br /> CSAH 63 (175th Ave) 0.08 0.09 0.35 <br /> 167th Ave 0.45 0.09 0.32 <br /> Ramsey Blvd 0.31 0.09 0.31 <br /> Sunfish Lake Blvd 0.09 0.33 <br /> Alpine Dr 0.21 0.42 0.90 <br /> Sunwood Dr 0.46 0.09 0.30 <br /> Dysprosium St 0.09 0.09 0.27 <br /> TH 47 0.42 0.68 <br /> Results of the detailed crash analysis indicate that the crash rates at the CSAH 5 intersections with <br /> CSAH 64 (181st Avenue), CSAH 63 (Green Valley Road), CSAH 57 (Sunfish Lake Boulevard), and <br /> TH 47 exceed the statewide average crash rate of intersections with similar characteristics. These <br /> locations are shown in orange in Table 5.Additionally,a review of the critical crash rate was completed <br /> to determine if the actual crash rates are statistically significant.The results in Table 5 show the CSAH <br /> 5 intersections with 167th Avenue, Ramsey Boulevard, and Sunwood Drive exceeds the critical crash <br /> rates of intersections with similar characteristics. These locations are shown in red in Table 5. Based <br /> on the results of the detailed safety analysis, safety improvements should be considered at these <br /> locations along the CSAH 5 study corridor. <br /> 9 <br />
