<br />The p.m. peak hour level of service was analyzed at ten eXlstmg and future <br />intersections shown in _' Analysis by the City's traffic consultant SRF was <br />conducted using both SYNCHRO 5.0 and SIMTRAFFIC traffic operations <br />analysis software. In general, a peak hour Level of Service D or better (on a scale <br />of A-F) is considered acceptable in the Twin Cities area. Intersections with level <br />of service D occasionally have traffic queues that do not clear within one signal <br />cycle. <br /> <br />Even with the assumed construction of Twin Lakes Parkway, several intersections <br />will require modification to maintain adequate Levels of Service. <br /> <br />Intersection Levels of Service <br /> <br /> Intersection Existing Build(l) <br />County Road D @ Cleveland B D(2) <br />Avenue <br />County Road D @ Fairview UnsignalizedJ D(2) <br />Avenue At Capacity <br />Cleveland Avenue @ Twin Lakes C D(2) <br />Parkway <br />County Road C2 @ Snelling C D(2) <br />Avenue <br />Cleveland Avenue @ County Road C D(2) <br />C <br />Fairview Avenue @ County Road E D or E(2) <br />C <br />Snelling Avenue @ County Road E E(2) <br />C <br />Prior A venue/County Road C Unsignalized/ B <br /> Under <br /> Capacity <br /> <br />Notes: <br />(I) P.M. peak hour level of service with mitigation, as needed <br />(2) See text for specific requirement <br /> <br />Modifications to intersections would be required as follows to mitigate traffic <br />impacts: <br /> <br />County Road D at Cleveland Avenue would require the addition of an exclusive <br />northbound left-turn lane. Although the majority of traffic to I-35W would use the <br />Twin Lakes Parkway, some will divert to the lower-volume County Road D <br />interchange. <br /> <br />County Road D at Fairview would require County signalization and the <br />reconstruction of the intersection to a four-legged intersection (by combining the <br />New Brighton Boulevard and Lake Johanna Boulevard approaches). This <br />intersection is currently an all-way stop and operates at capacity in the peak hour. <br /> <br />4 <br />
