<br /> ' ~ PAHOA COMPLEX OFFSITE IMPROVEMENTS TRAFFIC IMPACT ANALYSIS REPORT <br /> The pattern of hourly traffic volumes on the north leg of Highway 130 on June 22-23, <br /> 2004, is shown in tabular and graph form on Figure 4. The northwest bound traffic flow <br /> peaks in the morning between 6:00 to 9:00 AM, while the opposing southeast bound <br /> traffic peaks in the afternoon starting at 4:00 PM. The morning and afternoon peak hour <br /> 2004 volumes are lower than the 2006 volumes from the traffic turning movement <br /> counts shown on Figure 2, implying that traffic has increased in the last two years. <br /> I <br /> TRAFFIC FORECASTS <br /> The proposed project is scheduled for occupancy by 2008. During the two year period <br /> ' from the traffic count date to expected occupancy, ambient traffic on the area roadways <br /> can be expected to increase due to regional growth and new projects in the area. The <br /> I traffic that would be generated from the proposed project was added to the ambient <br /> traffic forecast to obtain the total with project traffic forecast. <br /> Ambient Traffic Forecast <br /> m There are no major development or construction projects planned along Highway 130 in <br /> the study area. Regional growth is occurring from infilling of the development areas <br /> I"~•- served by Highway 130, as evidenced by the high rate of traffic growth shown on <br /> Figure 3. Hence, ambient traffic on the study area roadways will increase due to <br /> regional growth in the adjoining areas. Therefore, the traffic growth rates indicated by <br /> the State DOT traffic volume counts were used as the index of regional traffic growth to <br /> I forecast year 2008. Based on these assumptions the following growth rates were <br /> established for the two-year forecast period: <br /> I Highway 130 5.5% <br /> • Old Keaau-Pahoa Rd 2.3% <br /> • Kahakai Boulevard 2.3% <br /> The existing traffic volumes at the two study intersections on Figure 2 were increased <br /> using the above factors. The results are summarized on Figure 5, with volumes <br /> rounded to the nearest five vph. The traffic operations for the ambient forecast <br /> conditions at the two study intersections are discussed in the Level of Service <br /> Analysis section of this report. <br /> M & E PACIFIC, INC.
