PAHOA COMPLEX OFFSITE IMPROVEMENTS TRAFFIC IMPACT ANALYSIS REPORT Traffic Volumes ~ Traffic turning movement counts were taken at the Old Keaau-Pahoa Road and Kahakai Boulevard intersections of Highway 130 on Thursday, September 21, 2006, for a two hour period during the morning peak and a three hour period in the afternoon peak. i Traffic turning movement counts require a traffic surveyor to observe traffic flow and record the movements of each vehicle crossing the intersection as through or turning ' movements by 15 minute intervals. In addition to vehicular traffic, very few pedestrians crossing the main highway or the side streets were counted. The worksheets for these traffic counts are included in Appendix A. The morning counts from 7:30 to 8:30 AM and early afternoon counts from 3:30 to 4:30 PM are shown on Figure 2, with volumes rounded to the nearest five vehicles per hour r (vph). These hours encompass the opening and closing of the two County offices and not necessarily the peak volumes of traffic on the roadway. The dominant direction of traffic on Highway 130 is northwest bound in the morning peak hour but the northwest bound volumes are nearly equal to the southeast bound volumes in the early PM peak. The southwest bound volumes are dominant later in the afternoon. The current traffic operations at the two study intersections are discussed in the Level of Service Analysis section of this report. The State of Hawaii Department of Transportation (State DOT) takes metered traffic counts at selected locations on Hawaii island roadways in even numbered years. Station 2-G is located at the study intersection of Highway 130 and Old Keaau-Pahoa Road. The data from these counts provides the historic trend in daily traffic volumes on I different legs of the intersections over six and eight year periods ending in 2002 and 2004. Data for the south leg of Highway 130 was available only from 1996 and 2002, I due to a meter malfunction in 2004. The biannual changes in two way daily traffic volumes on the two legs of Highway 130 and the Old Keaau-Pahoa Road are shown in tabular and graph form on Figure 3. The north leg and Old Keaau-Pahoa Road legs showed a decrease in traffic from 1996 to 1998, and increasing traffic thereafter. The I north leg of Highway 130 showed an 8.8% increase in traffic volumes over the eight ( year period while the traffic volumes on the Old Keaau-Pahoa Road increased 9.4%. l~ M & E PACIFIC, INC.
