These operations are likely <br />to exacerbate existing safety concerns and decrease mobility on the Highway 10 <br />corridor. The side-street stop-control access option is not recommended for the <br />Proposed Project. <br /> Full Movement Traffic Signal - The full signalized access option shows unacceptable <br />traffic operations with the existing four lane section on Highway 10. To achieve <br />acceptable traffic operations an additional through lane in each direction on Highway <br />10 would be needed. With traffic signal installation there are safety and mobility <br />trade-offs. Traffic signals have been found to increase crashes at an intersection, <br />especially minor rear-end crashes, and mobility of the corridor is decreased by <br />stopping mainline traffic. The full signalized access option is not recommended for <br />the Proposed Project as the cost for additional Highway 10 lanes is very high and <br />safety and mobility on the corridor could likely be inhibited. <br /> J-Turn Intersection - A J-Turn intersection is recommended for the access. A ¾ J-Turn <br />scenario with mainline lefts allowed and an eastbound right to southbound Highway <br />10 acceleration lane provides acceptable traffic operations while maintaining corridor <br />mobility and reducing fatal and severe crash potential. MnDOT has reviewed and <br />agrees with this recommendation. The Developer, City and MnDOT will work <br />together during the layout development process to determine the detailed geometrics <br />for the J-Turn intersection. <br /> <br />c) Identify measures that will be taken to minimize or mitigate project related transportation <br />effects. <br /> <br />The project will result in an increase to local traffic. A J-Turn intersection is recommended for <br />the interim access scenario at Highway 10 and 165th Ave NW. A ¾ J-Turn scenario with <br />mainline lefts allowed and an eastbound right to southbound Highway 10 acceleration lane <br />provides acceptable traffic operations while maintaining corridor mobility and reducing fatal and <br />severe crash potential. The Developer, City and MnDOT will work together during the layout <br />development process to determine the detailed geometrics for the J-Turn intersection. The future <br />Highway 10/Twin Lakes Parkway Interchange will provide long term access and remove the at- <br />grade Highway 10/171st Ave NW signal and mitigates the operational and safety concerns along <br />the TH 10 corridor. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />
