Modeling and Simulation

The Center for Transportation Analysis staff model a diverse array of phenomena from traffic flows to energy demand, from travel behavior to refinery operations. We have produced critical planning systems used every day by the U.S. Air Force to schedule and route airlift (CAMPS), and key components for the Department of Energy's National Energy Modeling System. We have designed and developed models for personal computers, mainframes and the internet, using a wide variety of languages and modeling tools.
