David King researches the codependence of transportation and land use planning along with transportation finance and economics. Of particular interest are transportation policies such as parking management, taxi services and microtransit, all of which integrate with land use planning. His work on finance examines how existing and new finance tools can raise revenues for more effective and just transportation systems. His current research focuses on taxi and jitney services, informal transit, street design, and how new technologies affect transportation finance and local policy.

In addition to academic accomplishments, King is a member of the Transportation Research Board’s Paratransit Committee and frequently consults with private firms and public organizations about challenges and opportunities in passenger travel, especially with regard to demographic and technological change.

King completed his doctorate at the University of California Los Angeles and a master's in urban and regional planning at the Humphrey Institute at the University of Minnesota.
