Policies and Practices Related to Passenger Vehicle Greenhouse Gas Reduction: Evidence and Assessment

In partnership with UC Irvine’s Institute of Transportation Studies and funded by the California Air Resources Board, Professor Susan Handy is reviewing the evidence on the effect of various regional and local strategies on vehicle miles traveled (VMT).

In response to the SB375 Regional Target Advisory Committee’s draft report recommendation that ARB work with technical experts and practitioners to develop and peer-review a list of land use and transportation policies and practices for reducing regional passenger vehicle greenhouse gas emissions, the California Air Resources Board awarded a team of researchers from the University of California funding to provide technical support during the development and refinement of the list. Specifically the UC researchers will

(1) identify which policies and practices on the list have supporting empirical data and evidence as to their effect on VMT,

(2) review and assess the evidence to provide conclusions on the size of the effect and the quality of the evidence , and

(3) provide easily understandable summaries of the review and conclusions, including the size of the effect on reducing greenhouse gas emissions through VMT reduction.

Topics include density, land use mix, transit access, regional accessibility, network connectivity, parking pricing, road pricing and employer trip reduction programs. Draft copies of these briefs can be viewed below.
