This update focuses on the development and analysis of the Transportation 2040 plan, including new features such as a land use forecast model, travel demand forecast model, emissions model, and benefit-cost analysis tool. Key topics covered include funding, environment, congestion, and alternatives analysis.

2010 DESTINATION 2030 Update A New Approach to Regional Transportation Plan Development and Analysis Transportation Research Board May, 2009 Jeff Frkonja, Matthew Kitchen, Mike Cummings, Maren Outwater, Larry Blain, Mark Simonson, Chris Johnson
Overview • Context: Regional Transporation Plan Update (new name: Transportation 2040) • Analytic Toolkit (Focusing on New Features) • Land Use Forecast Model • Travel Demand Forecast Model • Emissions Model • Benefit-cost Analysis (BCA) Tool • Evaluation Criteria • Planning & Analysis Application • Process • Analytic Results • Status
Destination 2030 becomes Transportation 2040 “Umbrella” Regional economic, land use, and transporation vision plan adopted under GMA: VISION 2040 Transportation Plan Update Scoping High Points: FundingShould user fees/tolls, potentially including a vehicle miles traveled charge, be a major source of future revenues to fund transportation investments? If so, how should they be applied, and how and where should revenues be spent? EnvironmentHow important are these issues in developing the (GHG/VMT)plan? Congestion How should the plan approach congestion & mobilityissues?

Transportation 2040 Alternatives Analysis • Applying Tools to the Planning Process
Overview: Analysis and Alternatives Construction VISION 2040: Regional Growth Strategy, Multicounty Planning Policies, Environmental Objectives Literature and Empirical Data Gathering across Modes and Potential Actions Take in Project & Program “Concepts” (Including Those in Existing Plan) Design Criteria Test Tolling Concept as Preliminary for Alternative Design Design Action Strategies across all Modes Step 1: Model Tolling Concepts Step 2: Model Alternatives Step 3: Produce Criteria Results (BCA, other quantitative, and policy) Alternatives Evaluation Report Analysis Tool Enhancements
Summary of Alternatives Strategies • Baseline • Uses adopted revenue sources to substantially fund committed projects • Starting point for comparing other alternatives • Alternative 1 • Designed to make our existing transportation system more efficient with traditional funding sources • Includes High Occupancy Toll lanes network on most of the highway system • Alternative 2 • Adds substantial roadway and transit capacity and 2 HOTlanes on much of the freeway system • Closest to our current plan and funded with traditional funding sources • Alternative 3 • Uses tolls to pay for a major portion of the most critical roadway improvements • Traditional funding would support new transit, and a better connected bicycle and pedestrian network • Alternative 4 • Uses tolls from the highway users to manage the roadway system and to fund a broad array of programs • Improves the system including roadway choke points, transit and non-motorized travel options • Alternative 5 • Largest expansion of high capacity transit, bus service, and dedicated bicycle and pedestrian facilities • Investments would be funded and roadway efficiency improved through tolling freeways and arterials • Uses all the traditional strategies from the other alternatives plus tolling to reduce carbon emissions
Evaluation Report Overview • VISION 2040 Policy Framework Environment Economy Development patterns Transportation • Transportation Objectives and Measures Improve mobility Protect environment Efficient land use Promote quality of life Promote prosperity Distribute costs and benefits • Evaluation Criteria Seven categories, 25 measures
Evaluation Report Findings: Emissions • Does reducing congestion reduce greenhouse gas emissions? Speed and the amount of travel are the key components for the amount of emissions produced – improving the flow of traffic* and reducing vehicle miles will reduce emissions. * Each pollutant has a specific “speed curve” – the optimal speed for reducing emissions is around 45-50mph
