Caroline Rodier has a Ph.D. in Ecology, focusing on environmental policy analysis and transportation planning. As a graduate student, she has designed, managed, researched, and helped procure funding for a number of public research projects. The research for these projects included the use of integrated land use and transportation, regional travel demand, and emissions models to evaluate the economic, equity, and air quality effects of a wide range of transportation and land use policies. Her dissertation addresses key issues of uncertainty in travel and emissions modeling, in particular, population projections and induced travel. She has earned a variety of awards including the University of California Outstanding Transportation Student of the Year, the Federal Highway Administration's Dwight David Eisenhower Transportation Fellowship, and the Environmental Protection Agency's Science to Achieve Results Fellowship. She has authored eight journal articles and seventeen reports and proceedings articles. Robert A. Johnston is a Professor of Environmental Planning at the University of California at Davis. He has been an expert witness in several important land use cases and has published over 60 refereed articles on land use planning, impact assessment, travel modeling and land use modeling. He has been a member of several transportation advisory bodies, and is currently a member of the National Academy of Sciences, Transportation Research Board, Committee on Transportation and Land Development
