of SR-132 is a four-lane freeway that extends from the Chrisman Road interchange east to the beginning of the transition from a four-lane freeway to the two-lane highway just east of the Chrisman Road interchange. Of the 16 reported accidents, eight(8)were listed as"hit object"accidents, four(4)as "rear end" accidents, two (2) as "sideswipe" accidents, and one (1) each as "overturn" and "broadside" accidents respectively. There was one(1) fatality accident reported which involved an overturn accident. The vehicle was traveling westbound and exited the freeway on the drivers left. The primary collision factor was noted as "influence of alcohol'. The accident occurred in mid-aftemoon on a clear day, during daylight hours and with dry pavement conditions. There were no unusual conditions noted. The actual accident rate for total accidents on SR-132 between PM 2.680 and PM 3.239 is higher than the ` corresponding average rate. This segment of SR-132 is a four-lane freeway that extends from east of Bird Road to the center of Interstate 5. Of the six (6) reported accidents, four (4) were listed as "rear end" accidents and two (2) as "sideswipe" accidents. All six (6) accidents were reported on westbound SR- 132. Five (5) of the accidents occurred between 5:45 a.m. and 6:50 a.m. with the first associate factor for all five (5) listed as "stop and go traffic" that indicates congested traffic conditions. SR-132 experiences significant traffic volumes in the westbound direction during the AM peak hour as commuter traffic passes through on their way to the Bay Area. The SR-132/Bird Road Interchange Project proposes to L construct both a new interchange on SR-132 at Bird Road (this will allow the existing at-grade intersection to be closed) as well as eastbound and westbound SR-132 auxiliary lanes between Bird Road and Interstate 5. Both of these improvements have the potential to reduce congested traffic conditions during the AM peak hour. The actual accident rate for fatal, fatal plus injury (F+I) and for total accidents on SR-132 between PM s 3.240 and PM 3.809 are higher than the corresponding average rates. This segment of SR-132 is a four- lane freeway that extends from the center of Interstate 5 east to the beginning of the transition back to a two-lane highway. Of the four (4) reported accidents, two (2) were listed as "overtum" accidents, and r one (1) each as "rear end" and "broadside" accidents respectively. There was one (1) fatality accident reported which involved a broadside accident. The vehicle involving the fatality was traveling eastbound, left the highway on the left side,crossed the median and was struck by a westbound vehicle. The primary collision factor was noted as "other violations". The accident occurred in mid-aftemoon on a clear day, .. during daylight hours and with dry pavement conditions. There were no unusual conditions noted. The proposed SR-132/Bird Road interchange is located at PM 2.24 and within the SR-132 segment ` between PM 1.160 and PM 2.679. As shown in the preceding table the actual accident rates within this segment are all lower than the corresponding average accident rates. Though the actual rates are lower than the average rates, the 3-year accident data was reviewed at and adjacent to the SR-132/Bird Road intersection. Between PM 2.230 and PM 2.260, seven(7) accidents were reported over the 3-year period. Three (3) were identified as "rear end" accidents, two (2) as "broadside" accidents, one (1) each as "sideswipe" and "hit object' accidents respectively. The two (2) broadside accidents and the one (1) i sideswipe accident involved collisions between vehicles proceeding straight on eastbound SR-132 and vehicles turning left into or out of Bird Road south of the highway. Of the three (3) rear end collisions, two occurred on eastbound and one on westbound SR-132 at the intersection. The westbound collision ` occurred at 6:10 a.m. with the first associate factor listed as "stop and go traffic'. The proposed interchange project proposes to construct a new interchange on SR-132 at Bird Road which will allow the existing at-grade intersection to be closed and all left tum movements eliminated from/to SR-132. ` TASAS Table B accident rates and Table B Accident Records information was also reviewed for the three year period from January 1, 2001 through December 31, 2003 for all eight ramps at the Interstate 5/State Route 132 cloverleaf interchange. Table 6 presents first the number of accidents and significance for the different ramps and then the resulting actual and average accident rates per million vehicles. i v 2nd Draft DeSilva Gates Quarry Trafc&Circulation Analysis 13 October 2005 i Jones&Stokes (R90577S002/25-4000-02)
