Dr. Clewlow's research expertise includes travel demand modeling, machine learning, and predictive analytics. Her prior research at MIT focused on examining the factors that determine the competitive and complementary nature of demand for aviation and high-speed-rail systems in Europe and Asia. Her recent work harnesses those same methods to understand current and potential future travel behavior implications of shared mobility (ride-hailing) and autonomous vehicles. The factors that influence individual travel behavior between cities are quite similar to the factors that influence travel within cities. Generally speaking, these decisions boil down to cost, time, transportation system service levels, trip purpose, individual attitudes, and the structure of the built environment. Regina's research focuses on developing new datasets and modeling tools to examine these decisions.
