Weekday.. <br />Intersection <br />Control <br />Delay <br />Delay <br />(seconds/.. <br />County Road B2 W at Snelling <br />Signal <br />vehicle) <br />23.6 <br />C <br />vehicle) <br />32.1 <br />C <br />Avenue SB <br />County Road B2 W at Snelling <br />Signal <br />7.8 <br />A <br />17.4 <br />B <br />Avenue NB <br />Internal Intersection # 1 A <br />Stop Control <br />2.9 / 6.8 <br />A / A <br />6.6 / 15.5 <br />A / C <br />Internal Intersection # 1 B <br />Stop Control <br />5.0 / 8.8 <br />A / A <br />12.0 / 17.1 <br />B / C <br />Internal Intersection #2 <br />Stop Control <br />6.1 / 7.1 <br />A / A <br />20.2 / 34.6 <br />C / D <br />Internal Intersection #3 <br />Stop Control <br />6.6 / 10.3 <br />A / B <br />8.1 / 16.5 <br />A / C <br />Internal Intersection #4 <br />Stop Control <br />1 5.3 / 9.0 <br />1 A / A <br />1 3.6 / 11.9 <br />1 A / B <br />Three intersections have movements that are not anticipated to operate at an <br />acceptable level of service during the weekday PM peak hour and/or Saturday peak <br />hour: <br />• Fairview Avenue at TH 36 (eastbound): During the Saturday peak hour, the <br />westbound left -turn movement is anticipated to operate at LOS F. This is due to <br />the queue spillback from the westbound right -turn movement. <br />• Fairview Avenue at TH 36 (westbound): During the Saturday peak hour, the <br />northbound left -turn and through movements are anticipated to operate at LOS <br />F. This is due to poor lane utilization for northbound traffic where the majority of <br />the through traffic is utilized the outside lane to position themselves to enter <br />Rosedale Center at the downstream intersection. <br />• Fairview Avenue at County Road B2 W: During the Saturday peak hour, the <br />eastbound right -turn movement is anticipated to operate at LOS F. <br />All other intersections (and their movements) are anticipated to operate at LOS D or <br />better during the weekday PM peak hour and Saturday peak hour. <br />c. Identify measures that will betaken to minimize or mitigate project related transportation <br />effects. <br />Improvements to the traffic network in the study area will be required to help mitigate <br />excessive queuing and delays. Only those improvements that could be implemented <br />without major reconstruction of the roadway and surrounding area were considered as <br />mitigation. The following improvements were assumed for the 2024 build -out year and will <br />need to be explored further with the City of Roseville, Ramsey County, and MnDOT: <br />• Fairview Avenue at TH 36 (eastbound) <br />o Convert the westbound right -turn from yield control to a free movement <br />o Optimize splits and offset for the traffic signal <br />• Fairview Avenue at TH 36 (westbound) <br />o Convert the northbound right -turn lane into a third northbound through <br />lane. This will require modifying the existing channelized islands on the east <br />side of Fairview Avenue, in addition to the relocation or replacement of <br />the northbound and eastbound approach signal poles and mast arms. <br />Rosedale Center EAW 20 February 2020 <br />
