June 2, 2011 <br />Page 4 <br />Savings Related to Reducing Crashes <br />The table below identifies the number of crashes that occurred at this intersection for the years 2007 <br />through 2009. The cost of each crash is categorized using the following criteria: <br />K =Crash involving a fatality <br />A =Incapacitating injury or one that is likely to require ambulance service <br />B =Non incapacitated injury that may or may not require ambulance service <br />C =Possible injury and property change <br />N =Property damage only <br />Crash costs are generated by Mn/DOT and the US Department of Transportation and are average <br />across the system. As is shown on the table, we converted the three year crash information into a <br />one year average and used the crash cost to arrive at a total crash cost for the intersection. At this <br />location, we assumed that HWY 101 would experience a crash reduction of 80% resulting in an <br />annual crash savings of $74,239/year related to Elk River travelers. <br />It should be noted that in the application Mn/DOT prepared for the SaM (Safety and Mobility) <br />funding, Mn/DOT added crashes to this intersection that previously occurred at South Diamond <br />Lake Road. These crashes were eliminated with the flyover project, but Mn/DOT has assumed that <br />they will resurface at this intersection. We did not assume the cost of these crashes in this <br />calculation in an effort to be conservative in our analysis. <br />Elk River Percentage i 5.895 <br />Eqc River Crash CosUyr $92,799 <br />Proposed Crash Reductior- 8095 <br />_, <br />
