Title:

Integration of Travel Demand, Land Use, and Emissions Modeling for a Transit Corridor Expansion Project in Santa Clara County California

Abstract:

Transportation activities accounted for 27 percent of U.S. greenhouse gas (GHG) emissions in 2008. Recently approved by the California State, AB32 and SB375 require each California metropolitan planning organization (MPO) to establish emission reducing goals and sustainable planning through the integration of land use development and transportation infrastructure investment policies. While this legislation is intended to apply to regional agencies, transit service and land use decisions are implemented at the local jurisdictional level. Therefore, assessing the possibility of changing land use development and transportation facilities to reduce GHG emissions is also an important planning issue for local planning agencies. This study integrates travel demand modeling with land use development strategies and emissions modeling to provide a method to evaluate various scenarios considering transportation, land use, and environmental impacts simultaneously. A case study of this integrated methodology to a transit expansion plan for the light rail system in Santa Clara County California is presented. Using Transit Oriented Development concepts, nine scenarios with denser residential and/or commercial land uses around new light rail stations are developed. The scenario comparisons show the densest mixed-use scenario has significant increases in transit ridership, non-motorized modes of travel and significant decreases in vehicle miles traveled (VMT) and emissions.
