It should be noted that this analysis <br />intentionally assumes signal cycle lengths that are longer than necessary at signals on the US- <br />70/I40 Connector as a means of modeling worst-case queues for storage length determinations. <br />As a result, actual delays and queues are expected to be better than presented in this analysis. <br />Table 3 summarizes the operation of the intersection for the projected build-out traffic conditions. <br />Table 3 <br />Level-of-Service Summary <br />Condition AM Peak Hour <br />LOS (Delay) <br />PM Peak Hour <br />LOS (Delay) <br />Saturday Peak Hour <br />LOS (Delay) <br />US-70 & Efland-Cedar Grove Road (Signalized) <br />Build-out Traffic – Phase 1 C (27.4)B (19.2)B (10.8) <br />Build-out Traffic – Phase 2 C (29.1)B (19.4)B (10.9) <br />Mt.
