E. Results of Analysis <br />This section contains the results of the intersection operational analyses based on Synchro/Simtraffic, 11 th <br />Edition, and provides recommendations, as necessary to mitigate the impacts. It is noted, the reported <br />results are from the aggregate of 10 SimTraffic simulations which use a random number generator to seed <br />the network with vehicles. These results reflect dynamic conditions and a more accurate than the results of <br />the static analysis reported by Synchro, however, due to random number generator can sometimes show <br />slightly better results on minor movements under higher traffic conditions when the intersections are <br />operating at very good LOS. Table 2 summarize the results of the operational analyses for the 2026 No <br />Build scenario (assumes 1.0 percent annual growth in traffic from existing conditions). <br />Table 2 <br />2026 No -Build Operations <br />Intersection <br />Overall/Worst Movement <br />LOS & Delay (sec) <br />Notes/95th Percentile Q <br />AM Peak Hour <br />PM Peak Hour <br />Variolite St NW & 173rd Ave NW/ <br />175t" Ave NW <br />a (0.4)/a nbl(1.7)a <br />()/ <br />(1.2)/a nbl(6.1)NB <br />()/ <br />Q is 27 ft in AM; <br />NB Q is 32 ft in PM <br />Variolite St NW & 161' Avenue <br />NW <br />a (1.4)/a wbt (6.6) <br />a (1.7)/a wbt (5.7) <br />EBQis37ftinAM; <br />EB Q is 43 ft in PM <br />Variolite St NW & Alpine Dr NW <br />a (1.9)/a sbl (3.8) <br />a (1.5)/a sbl (3.9) <br />SBQis45ftinAM; <br />SB Q is 32 ft in PM <br />Nowthen Blvd NW & 175th <br />Avenue NE <br />a (1.2)/a ebl (4.5) <br />a (2.3)/a ebl (5.6) <br />EBL Q is 43 ft in AM; <br />EBL Q is 30 ft in PM <br />Nowthen Blvd NW & 173rd <br />Avenue NW <br />a (0.8)/a nbt (1.1) <br />a (2.4)/a nbt (3.5) <br />NBL Q is 8 ft in AM; <br />EBR Q is 14 ft in PM <br />Nowthen Blvd NW & 167th <br />Avenue NW <br />a (3.4)/b ebl(11.1)a <br />()/ <br />(3.8)/b wbl(12.7)EB <br />()/ <br />Q is 30 ft in AM; <br />WB Q is 64 ft in PM <br />Nowthen Blvd NW & Ramsey <br />Blvd NW <br />a (3.9)/a ebl (8.1) <br />a (3.9)/b ebl (11.1) <br />EBL Q is 46 ft in AM; <br />EBL Q is 71 ft in PM <br />1. Overall Level of Service reported from SimTraffic delay, first letter represents intersection LOS, while second letter represents worst <br />LOS of individual approach. Upper case letters indicate signalized intersection, and lower-case letters indicate unsignalized intersection <br />2. 95th percentile queues are a result from an average of 10 SimTraffic simulations. <br />The results shown in Table 2 indicate all intersections and worst movements are expected to operate at <br />acceptable LOS in 2026 without the proposed project. Further, the results indicate all intersections will <br />experience short vehicle queues.
