Freeway Weaving Segment Operations: Table 40 presents the projected weaving operation between the I-5/SR-132 and SR-132/Bird Road interchanges. The first segment(referred to as Location 1 in Table 40) _ is the weave on westbound SR-132 between the southbound I-5 direct off ramp to westbound SR-132 and the westbound SR-132 off ramp to Bird Road. The second segment(referred to as Location 2 in Table 40) is the weave on eastbound SR-132 between the Bird Road on ramp and the eastbound SR-132 direct off _ ramp to southbound 1-5. As shown in Table 40, all design alternatives weave sections are projected to operate at LOS "D" on westbound SR-132 during the AM peak hour and LOS "D" on eastbound SR-132 during the PM peak hour. — TABLE 40 SR-132 BETWEEN I-5/BIRD ROAD INTERCHANGES WEAVING OPERATIONS _ YEAR 2027 PLUS PROJECT LEVELS OF SERVICE(LOS)WITH 4-LANE FREEWAY WITH SR-132/BIRD ROAD INTERCHANGE, ALTERNATIVES 1 THROUGH 3 _ _ AM Peak Hour PM Peak Hour Number of Basic Number of Basic Number oi'I,anus{N) Number of Lancs(N) —� Weaving Lanes(NB)in LOS Lanes(NB)in LOS Se ment Weavin Section to W'caving Sectiun Weaving Section m Weaving Section Location 1 2 3 D I3 Location 2 2 3 A 2 3 D Leisch Method(HDM,Figure 504.7A) Weaving section calculations under year 2027 plus project conditions were also evaluated within the I- 5/SR-132 freeway-to-freeway interchange. Table 41 shows the projected weaving operations within this interchange. The first segment(referred to as Location 1)is the weave on westbound SR-132 between the northbound I-5 loop off ramp and the loop on ramp to southbound I-5;the second segment (referred to as — Location 2) is weave on eastbound SR-132 between the southbound I-5 loop off ramp and the loop on ramp to northbound 1-5; the third segment (referred to as Location 3) is the weave on northbound 1-5 between the eastbound SR-132 loop on ramp and the loop off ramp to westbound SR-132; and the fourth segment (referred to as Location 4) is the weave on southbound 1-5 between westbound SR-132 loop on ramp and the loop off ramp to eastbound SR-132. As shown in Table 41, all weave sections are projected to operate at Levels of Service "C" or better during both the AM and PM peak hour periods with the exception of LOS"D"projected during the PM peak hour at Location 2.

Under all three design alternatives, SR-132 was considered to be a four- lane freeway at the merge and diverge. As shown in Table 42, the on ramp merge from Bird Road to westbound SR-132 is projected to operate at LOS "F" during the AM peak design hour for all three — design alternatives. As also shown in the table, the off ramp diverge from eastbound SR-132 to Bird Road is projected to operate at LOS"F"during the PM peak design hour for all three design alternatives. 2nd Draft DeSilva Gates Quarry Trafc&Circulation Analysis 44 October 2005 Jones&Stokes (R9057IS001/15-4000-02)
