Cynthia Chen's current research interests include human trajectory analysis (travel behavior analysis), demand forecasting, and survey methods. Broadly put, her focus is to understand human movements in time and space. She focuses on characterizing key characteristics of these movements, identifying regular and irregular patterns, and charting out the lifecycle of these patterns over time. Her past work has primarily focused on analyzing travel behavior dynamics in response to policy changes. She has also studied residential relocation choices by taking a lifecycle perspective. Her other works have also included deploying GPS technologies in travel surveys and designing rigorous experiments to evaluate the safety impacts of traffic calming measures.
