Graduate study focuses on developing and applying advanced network models, traffic flow theories, data analytics and simulation techniques to enhance the efficiency and safety of transportation systems. It has both the “traditional" aspect of civil engineering such as transportation planning, traffic operation, signal control and system management, and the “new” and “non-traditional” aspects such as rapid and disruptive technologies being developed and introduced into the field. Examples of the later category include Google Maps, Uber, connected and autonomous vehicles, usage-based insurance and many others. Graduate students in transportation engineering are expected to work closely with others departments such as engineering management and systems engineering, computer science, mathematics, etc.
