Mr. Christopher Yuen May 23, 2001 - 01 A-252 Page 6 • "Restrictions to prohibit driveways within 100 feet of Queen Kaahumanu Highway (as widened)." The applicant will comply. • "Install traffic signal conduits at the Luhia Street intersection." The applicant will comply, concurrent with further development of adjoining parcels. 5. "Required roadway improvements shall be provided by the applicant at no cost to the State." With regards to proposed improvements that are project-related and/or within the project area, the applicant will comply up to the level of its fair share. 6. "The LOS condition at the intersection of Kaiwi Street and Queen Kaahumanu Highway (Table 6-3, page 6-5) should be examined more closely. The traffic report should discuss why the left turn LOS (from Queen Kaahumanu) is equal to or better than a right turn LOS (onto Queen Kaahumanu). We feel that traffic improvements should be proposed for this intersection and the assumptions reconsidered (i.e., the 2020 with project evaluation assumed it would be STOP controlled)." The analyses of traffic conditions at the STOP sign-controlled intersection of Queen Kaahumanu Highway and Kaiwi Street reflects the methodology in Chapter 10, Unsignalized Intersections," of the Highway Capacity Manual Update, Special Report 209, 1997 (HCM). The delays to vehicles turning right from Kaiwi Street and left from northbound Queen Kaahumanu Highway are a function of two factors: A. The volume of the conflicting traffic they must cross or merge with, which is the southbound traffic on Queen Kaahumanu Highway for both turning movements. B. The length of the gap between southbound vehicles needed for the vehicles to make their crossing or merging maneuver, referred to as the critical gap. The critical gaps needed for vehicles to make aleft- or right-turn are presented in Table 10-1 of the HCM. With the future four-lane Queen Kaahumanu Highway, vehicles turning right from the side street typically need an average gap of 6.9 seconds between southbound vehicles to start up, turn into the southbound lane, and accelerate to avoid being overtaken and struck by the approaching vehicle.
