1 Analysis of Multi-Modal Strategies on Interregional Traffic in the I-580 Corridor in Northern California ITE Western District Annual Meeting June 25, 2012 Kamala Parks Senior Planner Jim Damkowitch Principal Planner

2 Project Goals 1.Develop the most cost-effective strategies to improve operational efficiencies on corridor 2.Quantify the interregional benefits 1.Trip reductions 2.Greenhouse gas (GHG) reductions

3 Presentation overview 1.Project Overview 2.Interregional Corridor Analysis A.Transportation Demand Management (TDM) B.Goods Movement Strategies C.Regional Transit Strategies 3.Interregional Multi-Modal Benefits A.I-580 Freeway Operations B.GHG Emission Reductions

4 Overview: Project Partnership Interregional Transportation Partnership (ITP) Caltrans (District 4 & 10) Alameda CTC Stanislaus COG ABAG San Joaquin COG MTC

5 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: I-580/I-205 Altamont Pass

6 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

7 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)

8 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)

9 TDM: Employer Based Analysis Market Share Demand Analysis HBW Trips affected by TDM Home-Based Work Trips Trips on I-580 Corridor County Trips

10 TDM: Trip Share Analysis by Trip Purpose I-580 Corridor Segments Percentage of Total Trips Home-Based Work Trips (HBW) is lion’s share

11 TDM: Trip Share Analysis by County Percentage of Traffic I-580 Corridor Segments

12 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 TDM: Interregional Scenario Development

13 TDM: Interregional Market Share (TDM1)

14 TDM: I-580 Specific Trip Reduction by Segment


16 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

17 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

18 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

19 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

20 Transit: Interregional Benefits I-580 trip reductions – 700 trips estimated for each peak-hour

21 Multi-Modal Benefits TDM Scenarios Regional Transit Regional Goods Movement LOS Improvement GHG Reduction

22 Trip Reductions: Interregional Benefits Peak hour trip reduction

23 Trip Reductions: Interregional Benefits Deficient lane miles of I-580 (Peak direction, 2035)

24 GHG Emission Reduction: Results Tailored EMFAC for I-580 corridor specific GHG estimates

25 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

26 Logical Next Steps Incorporate the county specific GHG emission reductions for participating counties and re-compute SB375 GHG Target metric (per capita GHG emissions) Base I-580 freeway operations analysis on simulation versus “static” HCM to provide a more direct comparison with the I-580 CSMP (i.e., added increment of operational improvement resulting from interregional employer based TDM, goods movement strategies and transit).
