Adelaide Landing Residential Development <br />Traffic Impact Analysis <br />1/31/2017 <br />Intersection Levels of Service are reported based on the Control Delay calculated for the <br />overall intersection and for each critical movement as determined by SimTraffic 9, and as <br />adjusted for driver behavior. <br />For queuing, SimTraffic reports found in the Appendix list the Mean Queue, the 95th <br />Percentile and the Maximum Queue Lengths that are generated after five runs. In this <br />report, the 95th Percentile Queue Length is used to discern adequate lengths of turn lanes. <br />The 95th Percentile Queue Length refers to that length of queue that has only a five - <br />percent probability of being exceeded during an analysis period. This is the standard factor <br />used to determine optimal turn lane lengths. These 95th Percentile Queue Lengths are also <br />found in the Appendix. <br />Table 3 illustrates the existing a.m. and p.m. peak hour levels of service at the study <br />intersections. Intersection levels of service are recorded on the left side of the table, while <br />lane group levels of service for critical approaches are reported on the right site of the <br />table. In addition, 951h percentile queue lengths for these critical approaches are also <br />reported. Existing MnDOT signal timings were used in modeling traffic operation. <br />None of the study area intersections presents unacceptable overall operational or <br />performance issues in the existing condition. <br />17 Westwood <br />
