Mc3rsu to the Plartniiae Dilt:cior � Ivl im:11 29.201 ti With regard to the TIAR included with the subject application, we provide the following. Under the nationally recognized Manual on Uniform Traffic Control Devices, traffic signals should tic-; installed only when they are warranted. Review of the projected volumes in the application's TIAR appears that some of the locations where traffic signals are rccommonded do not warrant their installation. These intersections include Komohana Street/Kukuau Street, Komohana Street/Puu Honu Place, Mohouli StroettPonohawat Street extension. The TIAR should consider ailernatives to traffic control signals even if one or more of the signal warrants have been satisfied. An alternative includes the adding of one or more lanes on a minor street approach - The TIAR recommends the widening of Komohana Street to 4 lanes from Waianuenue Avenue to Mohouli Street. The TIAR should address tate traffic impacts resulting from the widening on the operations of the intersection of Komohana and Punahele Streets. The TIAR recommends the west and east bound approaches at the intersection of Komohana and Ponohawai provide a dedicated left turn lane and a shared through/right turn lane. The 2015 projected volume in the west bound direction is 245(170) right turns during the a,m.(p.m.) peak hours, while through traffic is projected at 30(25) during the a.m.(p.m.) peak hours. It would seem that the intersection would operate better with the west bound approach providing a dedicated left turn, a dedicated through, and a dedicated right turn lane. Since the intersection is signalized, vehicles heading in the west bound through direction will block any of the right turn vehicles from making a right turn on red. The east bound approach is also projecting similar volumes coming out of the proposed project with a shared through/right turn lane. Similarly, the Mohouti Street west bound approach at its intersection with Komohana Street is also recommending as a shared through/right turn lane. The TIAR states that there is a 2% internal capture rate. On Table) for year 2015 with project, the entering and existing trips for the internal land uses should match one another. That is, entering traffic for the medical facility should equal the existing traffic for the commercial center. Also, Table 1 shows pass -by trips forthe internal trips. An explanation of how pass -by trips are considered internal trips should be provided. Note, the volumes for the internal capture is small and is unlikely that the changes will impact the analyses at the intersections. The TIAR utilizes a 34% pass -by trip rate for both the a.m. and p.m. peak hours. The TIAR should justify the use of the pass -by trip rate especially during the a.m. peak hour. The Institute of Transportation Engineers Trip Generation Handbook only provides pass -by trip rates for the p.m. peak hour of traffic. On page 17 of the TIAR, there is an emission within section 5.3.1.1 Ambient f=orecast, The first bullet "At tvtohouli Street" does not state which intersection the improvernent is recommended at. r` f iy0-`Ha'npi gI;,-yo'fel} isw,ihP i ani F nI)1 g
