Note,three,five, and ten years of crash data is used to form a statistical analysis. A three year study is typically <br /> used as a minimum for reliable data.This study uses 1.75 years of data which shows trends in the crash data <br /> however may skew the crash rate higher or lower than it may actually be. <br /> Between lanuary 2017 and September 2018,there have been seven total crashes at the intersection but only <br /> two that could be directly attributed to the intersection.The other five included run off the road crashes more <br /> related to the curve on TH 371 as well as a deer-vehicle crash. Neither of these 2 intersection related crashes <br /> resulted in a fatal or in-capacitating/serious injuries.A breakdown of the individual crashes is shown in the <br /> Appendix. <br /> The total crash rate of this intersection is 0.27 crashes per million entering vehicles (MEV)which is slightly above <br /> the statewide average of 0.26 crashes per MEV. However this intersection is significantly below the critical crash <br /> rate of 0.81 crashes per MEV, which means that this intersection is operating within the expected range. <br /> Proactive Risk Assessment <br /> MnDOT has created a Proactive Risk Assessment for intersections and highway segments that are more"at-risk" <br /> for severe crashes that do not exceed the critical crash rate as a means of prioritizing safety improvement <br /> projects.A set of risk factors were identified based on common factors present at locations with fatal and <br /> serious injury crashes. <br /> Risk factors (also called stars in the District and County Road Safety Plans)for rural four-lane expressway <br /> intersections include 1)skew of 10 degrees or more, 2) on/near a horizontal or vertical curve, 3) adjacent <br /> development,4) previous stop sign on the minor approach is greater than 5 miles, 5)volume cross product <br /> (multiplication of the major and minor approach average entering ADT) is greater than 6M, 6) severe right angle <br /> density(fatal and incapacitating injury crashes per intersection per year) is greater than 0.022,7) presence of a <br /> railroad crossing on the minor road.l <br /> �OR O O50 <br /> ! oas <br /> 15% � <br /> ,j 1 o ao <br /> wx � <br /> 1 0 oas <br /> �:sx „ � I oom� <br /> , <br /> �?OY �4 �� OOtS� <br /> b4 " <br /> 0 l5% `1 ��' 0.070� <br /> � <br /> � 1 <br /> i 0075 <br /> !0% ` <br /> ` + OQ3� <br /> 5�6 i 0 W5 <br /> a, I � s o 000 <br /> . �s �. �s �• �r �. <br /> s �� ,is '�+ +�+ <br /> • �♦ <br /> �Ot S�M <br /> �ke!�n�ertettlon� Seven[rasn[k�nvty —Seve•�H��p�un(�rcrat�[Ynvry <br /> Figure 3:Severe Crash Densities for Rural Intersections—Statewide CRSP Datal <br /> TH 371 at CSAH 29 Intersection Evaluation 6 <br />
