assume the roadways surrounding the site have the current configuration.

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 4 indicate all intersections and worst movements are expected to operate at <br />acceptable LOS in 2040 without the proposed project. Further, the results indicate all intersections will <br />experience short vehicle queues. (Again, when the operations of the intersection and critical movements <br />are at LOS A, the random number generator can sometimes result in slightly better delay or queuing results <br />on minor movements even with higher traffic conditions.) It is note, the left turning volume from Ramsey <br />Blvd to Nowthen Blvd is great enough to consider a change in traffic control in 2040 at this intersection, <br />however, the forecast operations and queues are acceptable. It is suggested this intersection be monitored <br />as volumes in the area grow to determine if safety or traffic control changes are needed. Table 5 summarizes <br />the results of the 2040 Build traffic operational analysis, assuming no improvements or mitigation. <br />Traffic Impact Study <br />Page 22 Sotarra - Trott Brook <br />S2 Traffic Solutions August 10, 2021 <br />
