  1. I-880Corridor System Management Plan ACTAC Meeting Alameda County Transportation Commission District 4 Office of System Planning Office of Traffic Operations Strategies September 7, 2010

  2. I-880 CSMP OverviewCMIA Requirements CSMP requirement is noted in the Baseline Agreements of all projects receiving CMIA funding. CMIA funding has been allocated for three projects on I-880: • NB/SB HOV Lanes, SR-237 to US-101 • SB HOV lane, Marina to Hegenberger • I-880/I-280/Stevens Creek Interchange

  3. I-880 (ALA/SCL) One of Nine TenCMIA Corridorsin Bay Area • US-101 North (MRN/SON) • US-101 Peninsula (SM/SCL) • I-80 East (SOL) • I-80 West (ALA/CC) • I-880 (ALA/SCL) • I-580 East (ALA) • SR-4 (CC) • SR-24 (ALA/CC) • SR-12 (NAP/SOL) • SR-84 (SM/ALA)(recently added)

  6. I-880 CSMP Background • Corridor Limits • From I-280 in Santa Clara County • to 7th Street in Oakland/Alameda County. • 42 miles including both Alameda • and Santa Clara segments. • Corridor Issues • Urban Development • Goods Movement • Connecting of Urban Centers • Severe Congestion

  7. I-880 Supporting Studies Coverage Map The CSMP incorporates and builds upon technical information from these studies The result is a system planning document to help guide future investment choices through traditional programming and planning processes.

  8. I-880 CSMP:Existing Conditions and Bottlenecks Growing VHD during analysis period (2004-2008). Most severe in PM Major bottlenecks at 23rd, 98th, Davis, Marina, Tennyson, Dixon Landing, Brokaw, US-101 and Bascom.

  9. I-880 CSMP:Recommended Strategies • Implement and enhance advanced/adaptive ramp metering throughout the corridor. • Complete CMIA and TCIF funded projects. • Construct interchange improvements and auxiliary lanes. • Complete HOV/express lane projects. • Key Improvement Metrics • 29% VHD reduction from ALA improvements compared to “do nothing” • 7/1 Benefit/Cost Ratio of Advanced Ramp Metering • Mobility maintained for HOV, still expect increased congestion for SOV.

  10. I-880 CSMP Document • CSMP Document Sections • Executive Summary • Section 1: CSMP Overview • Section 2: Corridor Description • Section 3: Performance Assessment • Section 4: Future Performance Assessment • Section 5: Strategy Evaluation and Recommendations • Appendices: Supporting Documents and Technical Documents

  11. I-880 CSMPNext Steps ACTAC September 7, 2010 VTA TAC September 9, 2010 ACTC September 23, 2010 CSMP Acceptance Late September 2010 CSMP Delivery to HQ Plng. and CTC Late September 2010

  13. For more information regarding the I-880 Corridor System Management Plan please contact: Caltrans: Katie Benouar, 510-286-5578 kbenouar@dot.ca.gov Erik Alm, 510-286-6053 ealm@dot.ca.gov Bob Rosevear, 510-286-5544robert_rosevear@dot.ca.gov

  14. I-880 Corridor:Future CSMPs • The “second generation” CSMPs • will take up the challenge of providing mobility and reducing highway congestion within the context of a new regional planning framework. • Sustainable Community Strategy as required by SB 375 • 2013 Regional Transportation Plan

  15. I-880 CSMP:Recommended Strategies • Implement and enhance advanced/adaptive ramp metering throughout the corridor (ICM) • Complete CMIA and TCIF funded projects. • Construct interchange improvements and auxiliary lanes. • Complete HOV/express lane projects. Map on CSMP pages ES3 and 5-15.
