Freeway Weaving Segment Operations: Table 21 presents the projected weaving operation between the <br /> I-5/SR-132 and SR-132/Bird Road interchanges. As part of the interchange project, an auxiliary lane will <br /> be constructed between the southbound I-5 direct off ramp to westbound SR-132 and the westbound SR- <br /> 132 off ramp to Bird Road. An auxiliary lane will also be constructed between the Bird Road on ramp to <br /> eastbound SR-132 and the eastbound SR-132 direct off ramp to southbound I-5. The weaving evaluations <br /> assume that these auxiliary lanes are in place and available for weaving. <br /> ►.

As shown in Table <br /> 21, all design alternatives weave sections are projected to operate at LOS `B" or better during both the <br /> AM and PM peak hours. <br /> r <br /> Ramp Junction (Merge/Diverge) Operations: Table 22 presents the projected Bird Road on ramp <br /> merge with westbound SR-132 and eastbound SR-132 off ramp diverge to Bird Road for all three design <br /> alternatives. Under all three design altematives, SR-132 was considered to be a four-lane freeway at the <br /> merge and diverge. As shown in Table 22, both ramp junctions were projected to operate at LOS "C"or <br /> better under all three design alternatives during both the AM and PM peak hours. <br /> TABLE 22 <br /> SR-132/BIRD ROAD INTERCHANGE RAMP JUNCTION OPERATIONS <br /> YEAR 2007 PLCS PROJECT CONDITIONS' LEVELS OF SERVICE(LOS)WITH 4-LANE FREEWAY <br /> (ALTERNATIVES 1 THROUGH 3) <br /> SR 132/ Alternative Alternative Alternative <br /> Bird AM Peak Hour PM Peak Hour AM Peak Flour PM Peak our AM Peak Hour PM Peak Hour <br /> Road Density Density Density Density Density Density <br /> Ramps (PC/ On) LOS ( e/ml/In LOS ( c/mi/In LOS ( e/mi/In LOS (PC/mi/In LOS (pe/mi/fn) LOS <br /> WB on <br /> from 17.2 B 1.8 A 17.2 B 1.8 A 17.2 B 1.8 A <br /> Bird Rd <br /> EB off to <br /> Bird Rd 5.2 A 21.3 C 52 A 21.3 C 5.2 A 21.3 C <br /> Roadway Segment Operations: With the Bird Road interchange project, SR-132 is proposed to be a <br /> four-lane freeway through the Bird Road interchange and immediately to the east and west of the <br /> interchange for all three design alternatives.

As shown in the table, these segments are projected to operate at LOS "B" <br /> or better during both the AM and PM peak hours.
