Driving and the Built Environment The Eects of Compact Development on Motorized Travel, Energy Use, and CO 2 Emissions Suburbanization is a long-standing trend reflecting the preference of many Americans for living in detached single-family homes and made possible through the mobility provided by the automobile and an extensive highway network. is study examines the relation- ship between land development patterns and vehicle miles traveled (VMT) in the United States to assess whether petroleum use, and by extension greenhouse gas emissions, could be reduced by changes in the design of development patterns. e committee that produced the report estimated that the reduction in VMT, energy use, and CO 2 emissions resulting from more compact, mixed-use development would be in the range of less than 1 percent to 11 percent by 2050, although committee members disagreed about whether the changes in development patterns and public policies neces- sary to achieve the high end of these estimates are plausible.

Preface In September 2008, the California state legislature passed the  rst state law (Senate Bill 375) to include land use policies directed at curbing urban sprawl and reducing automobile travel as part of the state’s ambitious strategy to reduce greenhouse gas (GHG) emissions.  e legislature recognized that cleaner fuels and more fuel-e cient vehicles would not be su cient to achieve the state’s goal of reducing GHG emissions to 1990 levels by 2020.  e bill requires the state’s 18 metropolitan planning organizations to include the GHG emissions targets established by the state Air Resources Board (ARB) in regional transportation plans, and to o er incentives for local governments and developers to create more compact developments and provide transit and other opportunities for alternatives to automobile travel to help meet these targets. ARB currently estimates that reductions in vehicle miles traveled (VMT) resulting from these actions will contribute only about 3 percent of the 2020 targets—an estimate that re ects uncertainties in the state of knowledge about the impacts of more compact development patterns on travel and the short time horizon involved.  e present study, which was requested in the Energy Policy Act of 2005 (Section 1827) and funded by the U.S. Department of Energy, is aimed at establishing the scienti c basis for and making appropriate ix [...]...x Driving and the Built Environment judgments about the relationships among development patterns, VMT, and energy consumption (see Chapter 1 and Appendix A for a full discussion of the study charge) The statement of task was expanded to include the impacts of development patterns on GHG emissions To carry out the study charge, the Transportation Research Board (TRB) and the Board on Energy and Environmental... housing choices Given the uncertainties, it would be wise to proceed carefully, monitoring the results and taking into account new research as it adds to the understanding of the benefits and costs that various compact, mixed-use development policies generate at different places and times 12 Driving and the Built Environment But given that the full energy and emissions benefits of land use changes will... compact development projects and was briefed on the impacts of Portland’s urban growth boundary on regional land use patterns and travel Finally, the committee thanks the following federal agency staff for their help in launching the study and their continuing assistance throughout: Philip D Patterson, Jr., of the U.S Department of Energy; Megan Susman and John V Thomas of the U.S Environmental Protection... have the greatest effect 1 2 Driving and the Built Environment The adverse effects of suburbanization and automobile dependence have long been evident but are currently of particular concern for several reasons First, after decades of low energy prices, the cost of oil rose to record highs in 2008, reflecting the growth of China and India and the instability of many key suppliers in the Middle East and. .. perspective on the committee’s charge; Reid Ewing, professor in the College of Architecture and Planning, University of Utah, who provided an overview of the land use–transportation literature; John Holtzclaw, consultant to the Natural Resources Defense Council, who spoke about location efficiency models; and John Landis, Chair of the xii Driving and the Built Environment Department of City and Regional... published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge The contents of the review comments and draft manuscript remain confidential to protect the integrity of the deliberative process The committee thanks the following individuals for their participation in the review of this report: A Ray Chamberlain,... congestion pricing and market-based parking fees, 10 Driving and the Built Environment along with zoning requirements for maximum rather than minimum parking, can complement higher-density development patterns that encourage transit use and pedestrian travel The Portland, Oregon, and Arlington, Virginia, case studies described in this report demonstrate how the application of these policies has led the real... over time Moreover, the committee has not examined the other benefits and costs of compact, mixed-use development or how the trade-offs among these benefits and costs might vary by the specific types of compact development policies and the contexts in which they are applied Nevertheless, climate change is a problem that is likely to be more easily dealt with sooner rather than later, and more energy-efficient... undeveloped land; increasing the nation’s dependence on petroleum, particularly foreign imports; and increasing greenhouse gas (GHG) emissions that contribute to global warming The primary purpose of this study is to examine the relationship between land development patterns, often referred to as the built environment, and motor vehicle travel in the United States and to assess whether petroleum use, and by... evaluating the potential benefits of information and education programs was not feasible through a scientific assessment because the 3 This addition was approved by staff of the U.S Department of Energy, which funded the study 18 Driving and the Built Environment link between such programs and policy outcomes in this arena is too tenuous to be established reliably from the literature Nevertheless, the committee .
