Copart USA Traffic Impact Study <br />Elk River, MN <br />1/14/2020 <br />on the main street are high and the corresponding vehicles per hour (one direction only) all fall <br />above 60 veh/hour (since the speed on the major street exceeds 40 mph). For the 2023 Build <br />condition, the southbound Jarvis approach records hourly volumes of 61, 69, 70, 87 and 117. If <br />any two of those hourly volumes drop below 60, the signal would not be warranted. <br />Warrant 3 is met based on the side street volume exceeding 75 vehicles per hour. One hourly <br />volume is 87 and another is 117. As with Warrant 2, if the southbound approach volume on <br />Jarvis drop[s below 75, the signal would not be warranted. <br />During the meeting with City staff from Elk River, Westwood learned that MnDOT is considering <br />signalization for the intersection. However, the type of signalized intersection being considered <br />for the intersection is a Reduced Conflict Intersection (RCI) with signalization. An example of <br />this type of intersection has recently been completed in East Bethel, MN, at TH 65 & Viking <br />Boulevard, as seen below. <br />Exhibit 1- Example of MnDOT-s Reduced Conflict Intersection with Signalization <br />fl <br />2 � <br />6:1 <br />Z f <br />a � <br />q <br />I- <br />1� { <br />ua <br />m <br />c <br />(Source: MnDOT website: http://www.dot.stote.mn.us/metro/prolects/hwy65rci/) <br />In this type of intersection, left turning traffic from the mainline has the opportunity to turn left <br />via a signal at the intersection with the cross street. However, cross street traffic wishing to <br />turn left onto the mainline must first turn right onto the mainline, merge to the left and make a <br />U-turn at a signalized intersection several hundred feet away from the cross street, and then <br />complete the turn onto the through lanes of the mainline in the desired direction. <br />In summary, Westwood recommends continued review of traffic patterns at the intersection as <br />they evolve. In addition, Westwood recommends continued discussions with MnDOT on the <br />viability of signalization or other forms of intersection traffic control at this location. <br />17 Westwood <br />
