Table 19 shows the projected year 2007 plus project study area truck trip distribution percentages. As shown in Table 19, approximately 43-percent of all aggregate trucks will initially be bound to/from the west on SR-132 from Bird Road and approximately 57-percent to the east. ► TABLE 19 VLAR 2007 PLUS PROJECT AGGREGATE TRUCK TRIP DISTRIBUTION Direction Distribution % -=Distribution Westbound on SR 132 to I-580 43% Northbound on I-580 43% Eastbound on SR 132 to 1-5 57% Eastbound on SR 132 beyond I-5 9% Northbound on I-5 41% Southbound on I-5 7% Total 100% 100% Figure 10 shows the projected year 2007 plus project AM and PM peak hour traffic volumes while Figure 11 shows the projected year 2007 plus project daily traffic volumes. ` YEAR 2007 PLUS PROJECT TRAFFIC OPERATIONS As previously noted,the SR-I32/Bird Road Interchange Project Report has identified and evaluated three interchange design alternatives (Alternative 1 through Alternative 3). The year 2007 plus project AM and PM peak hour traffic volumes for each interchange alternative are shown on Figure 12. The proposed design Alternative 1 through Alternative 3 intersection approach geometries for both Bird Road intersections with the SR-132 ramps are shown on Figure 9. Intersection Operations: Table 20 presents the projected year 2007 plus project intersection operations w for all three design alternatives. Forecasted intersection operations shown in the table are based on stop sign control on the respective eastbound and westbound SR-132 off ramp approaches to Bird Road. As shown in Table 20, the SR-132 ramp intersections with Bird Road are projected to operate at LOS `B"or .. better during both the AM and PM peak hours under all three design alternatives. As also shown in Table 20, the Blewett Road intersections with Bird Road and Koster Road are projected to operate at LOS "A/B" for both peak hour periods. Finally, the project access driveway would operate at LOS "A" for ` both peak hour periods. The project access driveway intersection with Koster Road was analyzed as single lane approaches with stop sign control provided on the access approach to the intersection.
