Future With Project Mitigation The November 2021 Final TIAR provided an analysis for all future years and a final mitigation recommendation for full buildout. Therefore, recommendations will be made for the updated intersections for the full buildout condition in Future (2039)with Project. 1. Royal Vistas Roadway Intersection All movements at the intersection of Route 11 and Royal Vistas Roadway are projected to operate at an acceptable LOS. No other improvements to this intersection are not recommended. 2. Kuakini Highway Intersection The Route 11 and Kuakini Highway intersection does not pass the 4-hour warrant or peak hour warrant when analyzing Route 11 as the major approach and Kuakini Highway as the minor approach due to the Kuakini Highway left turns not meeting the minimum traffic volume threshold. However, when analyzing the southbound Route 11 through as the major approach and the northbound Route 11 left turn as the minor approach (see Table 4), this intersection does pass the 4-hour warrant in Existing (2019). The satisfying of a signal does not require a traffic signal. Further analysis was done to check the effectiveness of a traffic signal at this intersection.
