2 Introduction The I-280 Corridor Study within Santa Clara County is a highway planning study led by the Santa Clara Valley Transportation Authority (VTA), in partnership with the City of Cupertino. The purpose of this study is to develop a strategic transportation improvement plan to identify areas of the transportation system that require short term and long range planning for the I-280 Corridor in Santa Clara County. The study extends approximately 22 miles between the San Mateo county line at the west and I-280/I-680/US 101 interchange in the City of San Jose at the east. Figure 1 illustrates the study corridor and the project limits. This technical memorandum summarizes the existing traffic conditions along the study corridor. The existing traffic conditions are based on a combination of data collected from a variety of sources including Caltrans Census Data, PeMS, ramp metering studies, manual counts and field observations of the freeway operating conditions. During the a.m. peak period, the peak direction of traffic is northbound on I-280 and during the p.m. peak period, the peak direction of traffic is southbound on I-280. Existing Vehicular Traffic Data Sources Table 1 lists the various sources of traffic data that were collected.

4 Existing Geometries and Lane Configurations Existing roadway geometric data was collected using aerial photographs from Google Earth and was verified during the field observations. Figures 2a to 2e illustrates the existing lane configurations along the freeway mainline and ramps within the study limits. A High Occupancy Vehicle (HOV) lane exists along both directions of the freeway between North of Leland Avenue in the City of San Jose and Magdalena Avenue in the City of Los Altos. The existing HOV lane operation hours are from 5:00 a.m. to 9:00 am and from 3:00 p.m. to 7:00 pm for both northbound and southbound directions. Currently, there are 24 interchanges along I-280 within the study area including four system interchanges. The system interchanges are: I-280/US 101, I-280/SR 87, I-280/I-880/SR 17 and I-280/SR-85. The number of travel lanes varies between three and five lanes in each direction with auxiliary lanes between some of the interchanges. Auxiliary lanes are present in the following locations Northbound US 101 to 7 th Street 10 th & 11 th Street to SR 87 SR 87 to Race Street/Southwest Expressway Meridian Avenue to I-880 Winchester Boulevard to Saratoga Avenue Saratoga Avenue to Lawrence Expressway Stevens Creek Boulevard to N Wolfe Road De Anza Boulevard to SR 85 SR 85 to Foothill Expressway Southbound Direction Page Mill Road to Magdalena Avenue Foothill Expressway to SR 85 SR 85 to De Anza Boulevard N Wolfe Road to Stevens Creek Boulevard Lawrence Expressway to Saratoga Avenue Saratoga Avenue to Winchester Boulevard I-880 to Meridian Avenue Meridian Avenue to SR 87 SR 87 to 10 th & 11 th Street 10 th & 11 th Street to US 101 Interchange Configuration I-280 corridor in a Santa Clara County is approximately 22 miles of freeway that goes through City of San Jose, City of Santa Clara, City of Cupertino and City of Los Altos. I-280 connects cities with local interchanges and also intersects with major system interchanges at US 101, SR 87, I-880/SR17 and SR 85 before it enters into San Mateo County. Brief interchange description is provided here: 1-3

Northbound I- 280 off ramp is a two lane exist that provides access to both NB/SB Page Mill Road. Northbound I-280 on ramp is a single ramp that merges loop and diagonal ramps before entering the mainline. I- 280 southbound on/off ramps configurations are identical to the northbound described above. There are currently no ramp meters at this location. 1-9

11 Ramp Metering Locations AECOM did field observations to identify the possibility of adding a lane to the ramps, and as well the number of lanes at the freeway on ramp merges. Caltrans provided ramp metering information including the number of lanes on onramps, metering rates and times of operation. The summary of field observations and information from Caltrans is provided in the Appendix A.

12 Existing Traffic Flow Data Sources of traffic flow data along the study corridor are: A. Caltrans Census: 24-hour traffic volumes along the study corridor were collected from the Caltrans Census. The data was then processed to determine the average weekday volumes during both the a.m. peak periods and p.m. peak periods. B. Caltrans PeMS: The 24-hour weekday (Tuesday, Wednesday and Thursday) traffic volumes and speeds from various Vehicle Detection Stations were collected along the study corridor. The data was then processed to determine the average weekday volumes during both the a.m. peak periods and p.m. peak periods. C. Manual Counts: Weekday peak period counts (6 am to 10 am and 3 pm to 7 pm) were collected at the following four locations during both the a.m. and p.m. peak periods. I-280 NB AM Mainline counts at Mora Drive Overcrossing I-280 NB AM Mainline counts at Pedestrian Overcrossing west of I-880 I-280 SB PM Mainline counts at Mora Drive Overcrossing I-280 SB PM Mainline counts at Bascom Avenue Overcrossing D. VTA Forecast Model: Peak period counts were extracted from the model at some of the on/off ramps within the study corridor where no information was available from other flow data sources. Peak hour, Peak period and ADT volumes obtained from these different sources are listed along the freeway mainline and along the freeway ramps are shown in Figures 2a to 2e. AADT along the I-280 corridor varies between 96,000 vehicles per day (vpd) (@Alpine Road) and 246,000 vpd (@McLaughlin Avenue) based on Caltrans 2014 Traffic Volumes. Existing Peak Periods Based on the review of Caltrans Census and PeMS data, and from field observations the peak periods were identified to be between 6:00 a.m. and 9:00 a.m. in the mornings and between 3:00 p.m. and 7:00 p.m. in the evenings. Even though congestion continues beyond the peak periods, the Single Occupancy Vehicles (SOV) can use the HOV lane after these peak periods. Based on travel time runs and counts, this project assumes the peak hour for the corridor within the study limits is 7:00-8:00 AM and 5:00-6:00 p.m. in the evening. The traffic flow data and the corresponding sources are provided in the Appendix A. Existing Bottlenecks and Queues Several bottlenecks and queues were observed along the study corridor in both directions from the field observations conducted in February Northbound AM Peak: Bottleneck was observed between 7 th street off ramp and SR 87 NB/SB off ramp. The congestion on SR 87 NB is causing backup on the off ramp that extends onto the I-280 mainline. Right lane overload is observed at this location due to heavy merge and weave traffic volume from the closely spaced on and off ramps. The mainline queue extends along I-280 beyond US 101 interchange. The other contributing factors for this long queue include; closely spaced US 101 NB/SB on ramp merge location, McLaughlin Avenue on ramp, 7 th and 11 th street off ramps, 10 th and 4 th street on ramps and a lane drop at 7 th Street off ramp. The next bottleneck was observed at the mainline lane drop just south of I-880/SR 17 off ramp and Stevens Creek Boulevard off ramp. The queue from this bottleneck extends along I-280 beyond Meridian Avenue (occasionally it extends to SR 87). 1-11

13 Slow moving traffic was observed in all lanes from SR17/I-880 to De Anza Boulevard because of heavy on ramp traffic from SR 17/I-880 and off ramp traffic at Lawrence Expressway, Wolfe Road, and De Anza Boulevard interchanges. Another bottleneck was observed between SR 85 on ramp and Foothill Expressway off ramp due to heavy weaving and less interchange spacing. The queue from this bottleneck extends beyond the SR 85 interchange (occasionally it extends to De Anza Boulevard). HOV Lane was observed to be congested from Meridian Avenue to Saratoga Avenue due to heavy traffic merge and weave between HOV lane and SOV lane at SR17/I-880 interchange. Northbound PM Peak: Slow moving traffic observed at the Page Mill Road due to a lane drop before the Page Mill Road interchange. Southbound AM Peak: There is no congestion observed in southbound direction during AM peak, except for a very short segment from 11 th Street to 7 th Street. This segment is observed to have slow moving traffic. Southbound PM Peak: A bottleneck was observed at Magdalena Avenue off ramp due to inadequate mainline capacity and one of the mainline lane becomes exit lane for the off ramp. The queue from this bottleneck extends beyond the Page Mill Road interchange. Another bottleneck was observed at the SR 85 off ramp due to heavy off ramp volume to SR 85 southbound and the mainline capacity constraint of SR 85. The queue from this bottleneck extend up to Magdalena Avenue and join the upstream bottleneck at Magdalena Avenue. Several major bottlenecks were observed at SR 17/I-280, SR 87/I-280 and US 101/I-280 interchange due to inadequate capacity of the intersecting freeways such as SR 17 southbound, SR 87 southbound and US 101 southbound. The queues from these bottlenecks connect each other and extend to De Anza Boulevard. Figures 2a-2e summarize the bottleneck and queues observed for northbound am and southbound pm peak periods. 1-12

14 HOV Lane Usage Based on the Caltrans Managed Lanes report, the percentage of the total traffic that uses the HOV lane during both the a.m. peak hour and p.m. peak hour was identified and summarized in Table 2. Table 2: Existing HOV Percentages DIRECTION/ PEAK HOUR HOV LANE LIMITS PERCENTAGE OF TRAFFIC USING HOV LANE Northbound/ AM Peak Hour Leland Avenue to Magdalena Avenue 18 1 Southbound /PM Peak Hour Magdalena Avenue to Leland Avenue 12 2 Source: 1 Caltrans 2013 Managed Lanes Report 2 Caltrans 2012 Managed Lanes Report Caltrans goal is to keep the HOV violation rate to less than 10%. However, the violation rate is higher in both peak periods due to heavy congestion in General Purpose (GP) lanes. Truck percentages Table 3 summarizes the truck percentages based on Caltrans 2014 Truck volumes. The truck percentages range from a low of 1.53% to a high of 4.7% which are similar percentages to other freeways in the Bay Area.

This includes previous corridor studies, ramp metering reports, Congestion Management Program (CMP) reports, traffic impact analysis reports, city planning documents, GIS data, existing count data from the City of San Jose and Santa Clara County, available VTA transit information, and SWITRS (Statewide Integrated Traffic Records System). Traffic Data Roadway segment and ramp counts were gathered from a variety of sources. Much of the data was gleaned from 2014 CMP counts. Transit Data All of the transit data included in this report was provided by VTA. Transit stop location, ridership, and transit facilities were taken directly from GIS data provided by VTA. VTA route information including direction and peak headway was taken from available VTA schedules and maps. Bike Data Existing bicycle data and route information was available from the Santa Clara Countywide Bicycle Plan (VTA, August 2008). Additional GIS data received from VTA was used for bike facility classification and route location. Collision Data Collision data for the study area was available through the Statewide Integrated Traffic Records System (SWITRS). The data looked at for this report was a five-year span from January 2010 to December SWITRS indicated with no specified reason that some 2014 data may be incomplete. The Transportation Injury Mapping System (TIMS) was used to determine specific collision locations. TIMS is an interactive map based on SWITRS data. 2-3

28 INTERCHANGES I-280 interchange data and information was obtained from existing sources. In most cases, available counts at nearby intersections were used to derive the peak hour cross street segment volumes traveling across I-280. Table 9 summarizes the speed limits, number of lanes, and existing peak hour segment volumes at each cross street of I-280 with an interchange. Existing peak hour segment volumes are from the highest peak hour (AM or PM), where available. Volume shown is one-directional in the direction towards I-280.

31 BIKE FACILITIES Within the study area, there are a number of existing and planned cross-county bike corridors. These corridors are described in the 2008 Santa Clara County Bicycle Plan and are an important part of the overall bike network. The purpose of the Cross County Bicycle Corridors network is to provide continuous connections between Santa Clara county jurisdictions and to adjacent counties, and to serve the major regional trip-attractors in the County. For the most part, the corridors use city streets, ranging from major arterials to quiet residential streets. Twenty-four (24) cross-county bike corridors and seventeen (17) bike trails make up the Santa Clara County bike corridor network. Eleven (11) cross-county bike corridors and four (4) bike trails extend through the study area. The bike paths and cross-county corridors located within the study network are summarized in Table 11.

32 In addition to the cross-county bike corridor network, there are many existing bike facilities on the streets parallel to and crossing I-280. Bike facilities are typically categorized into four classes: Off-street Paths (class I), On-street Lanes (class II), Signed Routes (class III), and Cycle Tracks (class IV). An example of each class is shown below. Off-street Path (Class I) On-street Lane (Class II) Signed Route (Class III) Cycle Track (Class IV) Class I bike facilities cross I-280 at the following locations: Don Burnett Bicycle Pedestrian Bridge (8 ft wide) Guadalupe River Trail (10 ft wide) El Monte Road Connections are planned for the Stevens Creek Trail and the Coyote Creek Trail to cross I-280 in the future. Class II bike facilities cross I-280 at the following locations: Arastadero Road (5 ft wide) Stelling Road (5 ft wide) De Anza Boulevard (5 ft wide) Wolfe Road (5 ft wide) Blaney Avenue (4 ft wide) Tantau Avenue (5 ft wide) Stevens Creek Boulevard (6.5 ft wide) 2nd Street (6.5 ft wide) 3rd Street (6.5 ft wide) 7th Street (5 ft wide) 10th Street (6 ft wide) 11th Street (5.5 ft wide) McLaughlin Avenue (5 ft wide) Class III bike facilities cross I-280 at the following locations: Robleda Road 2-8

33 Appendix E shows the existing bike facilities in the I-280 study area. Across Barrier Connections In some locations within the study area, I-280 creates an impermeable barrier for pedestrians and bicyclists. Even when a roadway crosses, it may have inadequate or have no accommodations for bicycles (bike lanes or shoulders meeting bike lane standards) and/or pedestrians (sidewalks). The 2008 Santa Clara Countywide Bicycle Plan identifies these barriers as an issue that should be addressed with "across barrier connections". Across barrier connections are bike/pedestrian-only bridges or tunnels across a freeway, creek, or railroad, or an atgrade pedestrian crossing of railroad tracks. In some cases, a cross-street may be considered an "adequate roadway crossing". A roadway is considered to provide adequate bike access if it is a collector or arterial roadway with bike lanes or wide shoulders meeting bike lane standards, or it is a local road with low traffic volumes. A roadway is considered to provide inadequate bike access if it is a collector or arterial and does not have a bike lane or wide shoulders. Segments of I-280 are considered to be "gaps" if there is a mile or more between existing crossings (adequate and inadequate). According to the 2008 Santa Clara Countywide Bicycle Plan, the study area along I-280 includes five (5) existing across barrier connections, twelve (12) existing adequate crossings, seventeen (17) existing inadequate crossings, and four (4) existing gaps. Table 12 lists arterial crossings in the study area that do not have bike lanes or shoulders according to the 2008 Santa Clara Countywide Bicycle Plan. Table 13 identifies the gap locations within the study area that are included in the 2008 Santa Clara Countywide Bicycle Plan.

34 PEDESTRIAN FACILITIES Pedestrian facilities consist of sidewalks, bridges, crosswalks, and pedestrian signals. Along the I-280 corridor study area, there are four pedestrian overcrossings. These overcrossings are shown in Figure 1 and listed below. I-280 Pedestrian Overcrossing Locations: 0.30 miles east of SR-85 (Don Burnett Bicycle Pedestrian Bridge) 0.18 miles east of San Tomas Expressway 0.17 miles west of I miles east of Leigh Avenue Aside from pedestrian overcrossings, many of the streets crossing I-280 have existing sidewalks for pedestrians. Table 14 summarizes the existing sidewalks at each cross street within the study area COLLISION DATA Collision data was gathered from the Statewide Integrated Traffic Records System (SWITRS). This corridor study looked at five (5) years of collision data within 500 ft of each interchange. This included collisions on the mainline, on-ramps, off-ramps, and cross-streets. The most recent five-year span with available data is The data shows a higher concentration of collisions along the eastern portion of the study corridor. S Bascom Avenue has the highest number of vehicle collisions within 500 feet of the interchange with 122.
