Analysis of Multi-Modal Strategies on Interregional Traffic in the I-580 Corridor in Northern California Kamala Parks Senior Planner Jim Damkowitch Principal Planner ITE Western District Annual Meeting June 25, 2012
Project Goals • Develop the most cost-effective strategies to improve operational efficiencies on corridor • Quantify the interregional benefits • Trip reductions • Greenhouse gas (GHG) reductions
Presentation overview • Project Overview • Interregional Corridor Analysis • Transportation Demand Management (TDM) • Goods Movement Strategies • Regional Transit Strategies • Interregional Multi-Modal Benefits • I-580 Freeway Operations • GHG Emission Reductions
Overview: I-580/I-205 Altamont Pass • Major link between San Francisco Bay Area (Jobs) and Central Valley (Housing) • 32 miles long • Annual Traffic Growth • 1992-2009 = 2.5% • 2000-2006 = 4.5% (Pre-recession) • Important truck route • Truck Traffic = 9% • Port of Oakland
Overview: Context of the Study • Adjunct to I-580 Corridor System Management Plan (CSMP). • Intelligent Transportation System (ITS) improvements • Ramp Metering • Signal Optimization • Freeway Service Patrol (FSP) • Auxiliary Lane & Ramp Improvements • Extension of HOV/HOT Lanes • Interchange improvements • Additional transit and TDM improvements
Overview: Analysis Tools • Travel Demand Forecasts • Regional (SJCOG, MTC) and County (Alameda CTC) travel demand models • Regional Transit Ridership Forecasts • BART to Livermore Extension Preferred Alternative Memorandum, BART • California High Speed Rail Project Ridership and Review Forecasts, Cambridge Systematics • Truck Forecasts • Alameda CTC truck model • American Trucking Association (ATA) • Bay Conservation and Development Commission (BCDC) • Programmed improvement projects (FTIP/STIP, Port Projects etc.) • TDM Trip Reduction • TRIMMS software (FHWA) • Corridor Operation Analysis • Highway Capacity Software (McTrans) • Greenhouse Gas Reduction Analysis • EMFAC/BURDEN (CARB)
Overview: Analysis Structure • Analysis years • Baseline • 2020 (near-time) • 2035 (long-term) • 7 County analysis • 5 in the San Francisco Bay Area • 2 in Central Valley • 10 segments of I-580 corridor (~32 miles) • I-238 (west most termini) • I-580 • I-205 (east most termini)
TDM: Employer Based Analysis • Market Share Demand Analysis • HBW Trips affected by TDM • Home-Based Work Trips • Trips on I-580 Corridor • County Trips
TDM: Trip Share Analysis by Trip Purpose • Home-Based Work Trips (HBW) is lion’s share Percentage of Total Trips I-580 Corridor Segments
TDM: Trip Share Analysis by County Percentage of Traffic I-580 Corridor Segments
TDM: Interregional Scenario Development • 4 Scenarios, all assumed: • Mandated TDM • San Joaquin Valley Air Pollution Control District e-TRIP (Rule 9410) • TDM as conditions of approval • San Joaquin and Stanislaus Counties • TDM1 • Commute Benefits Ordinance for Bay Area • TDM2 • Bay Area Commute Benefits Ordinance and TDM Conditions of Approval • TDM 3.1 and 3.2 • Parking Pricing in Bay Area: $7/day & $15/day, respectively
Goods Movement: I-580 Truck Forecasts • Growth Factor Method • Socio-economic growth projections • ATA Truck projections • BCDC Port projections • Alameda CTC truck model • Model driven by socio-economic projections • Chose Growth Factor Method
Goods Movement: Interregional Strategies • Highway related projects • Truck climbing lanes • Lane widening • Intermodal Facility Expansions (rail and truck) • San Joaquin and Stanislaus Counties • Marine Highway • Dredging between San Francisco Bay and the Port of Stockton to enable larger vessels to serve Port of Stockton • Reduce the need to truck containers on I-580
Goods Movement: Interregional Findings • Significant truck reduction on I-580 corridor in peak-hours not likely: • I-580 has no logical alternative for large trucks • Cost of short-haul rail transfers to truck • However, daily truck reductions will accrue on the I-580 corridor due to the projects • LOS improvements due to truck climbing lanes
Transit: Interregional Strategies • High speed rail spur • Stockton-San Jose • Altamont Commuter Express (ACE) rail enhancements • Its own right-of-way (not shared with freight) • BART extension to Livermore • Connection to ACE • Other Regional Transit Improvements • Captured by TRIMMS analysis
Transit: Interregional Benefits • I-580 trip reductions • 700 trips estimated for each peak-hour Treehugger.com
Multi-Modal Benefits • LOS Improvement • GHG Reduction
Trip Reductions: Interregional Benefits • Peak hour trip reduction
Trip Reductions: Interregional Benefits • Deficient lane miles of I-580 (Peak direction, 2035)
GHG Emission Reduction: Results • Tailored EMFAC for I-580 corridor specific GHG estimates
Study Products • Quantified county specific trip/VMT reduction benefits from TDM • Methodology for analyzing a corridor from regional and county models • GHG emission reductions from employer-based TDM programs • Interregional policy and strategy considerations • Employer-based TDM • Transit • Goods movement • Project website and video • Use and circulation by all participating agencies
