Dan Chatman studies travel behavior and the built environment; residential and workplace location choice; "smart growth" and municipal fiscal decision making; and the connections between public transportation, immigration and the economic growth of cities. His research relies heavily on original data collection, including surveys, focus groups and interviews. Ongoing and recently completed research projects include studies addressing which U.S. transit systems succeed and why; the implications of immigration trends for sustainable development and economic growth; the relationship of transit investments to agglomeration economies in U.S. cities; the effect of dynamic parking pricing on occupancy and use of on-street parking in San Francisco; and the relationship between residential location, commuting, and happiness.
