Ritchie studies transportation systems engineering and is specifically interested in advanced traffic management and control systems. He is primarily focused on the development and application of new information technologies to support more efficient transportation systems.

Professor Ritchie’s research interests focus on intelligent and sustainable transportation systems planning and engineering. Particular interests include new and innovative approaches for statewide freight transportation and commodity flow modeling, for infrastructure investment and environmental analysis; development of data sources, sampling frameworks and new survey instruments to estimate statewide commercial vehicle utilization; collection and integration of high-resolution sensor data for advanced real-time modeling and classification of heavy duty truck characteristics and movements; modeling and assessing the GHG, energy, air quality and health impacts of transportation operations and alternative fueled vehicles; and real-time freeway and arterial traffic performance measurement based on inductive signature vehicle reidentification.

Ritchie serves as founding editor-in-chief of the international journal, Transportation Research Part C: Emerging Technologies, published by Elsevier Science.
