I PAHOA COMPLEX OFFSITE IMPROVEMENTS TRAFFIC IMPACT ANALYSIS REPORT seconds, traffic queues are short, and there are no reasonable mitigating measures available. ~'m.~, Table 2 summarizes the unsignalized intersection level of service analysis for the Highway 130 study intersections. For each of the morning and afternoon peak hours, the existing, 2008 ambient and total with project forecast are placed side by side. This I format facilitates a comparison of levels of service for the different forecast scenarios to give an indication of the traffic impacts of ambient traffic growth and the proposed 1 project. Levels of service are given for the following approaches and movements: side street approach and its left and right turn movements, and Highway 130 left tum movement. The worksheets for the level of service calculations are provided in Appendix B. The results on Table 2 show that the left turn movement from the Old Keaau-Pahoa Road is already at level of service F in both peak periods, with calculated delays of 126 seconds in the morning and 81 seconds in the afternoon. Consequently, the calculated I queue length is 10 vehicles in the morning and 8 vehicles in the afternoon. Therefore, this would indicate that the left turn movement is operating at an undesirable level of service. I The Kahakai Boulevard left turn movement is at level of service E in both peak periods, with calculated queue lengths of 4 vehicles in the morning and 2 in the afternoon. The I right turn movements from both side street approaches are currently at level of service B in both peak periods. The left turn movements from Highway 130 into Old Keaau- Pahoa Road and Kahakai Boulevard are at level of service A in both peak periods. The I above results would indicate that the other movements at both study intersections are at acceptable levels of service, although the outbound left turn movement from Kahakai Boulevard is minimally acceptable. The additional traffic from the ambient traffic forecasts would further lengthen the delay I times and traffic queue lengths on the left turn movement of Old Keaau-Pahoa Road, _ which is already at level of service F. Delay is calculated to increase from 126 to 180 M & E PACIFIC, INC. PAGE 8 60016945.00300 December 2006 Pahoa Complex TIAR.doc
