Research interest

Mathematical representations of transport systems to support the planning and management of mobility and infrastructure. Key domain interests include new models for transport network performance that account for emerging applications spanning information, uncertainty and dynamics. Specific research methodological contributions have included dynamic traffic assignment, stochastic routing, network design, planning for ITS, mobility as a service, adaptive equilibrium, network behaviour under information and bi-level optimisation of mobility networks.

Bio

Professor S. “Travis” Waller is the Honorary Professor, and the former Head of Schoo of Civil and Environmental Engineering, Faculty of Engineering at the University of New South Wales. Prof. Waller received his BS in Electrical Engineering from The Ohio State University and his MS/PhD degrees in Industrial Engineering and Management Sciences from Northwestern University.  Prior to joining UNSW, Prof. Waller was on the faculty at the University of Texas at Austin in the Department of Civil, Architectural & Environmental Engineering. Prior to UT-Austin, he was in the Department of Civil Engineering at the University of Illinois at Urbana-Champaign and earlier worked as a Postdoctoral Research Fellow at Northwestern University.

At UT-Austin, Prof. Waller led the successful effort to establish (and served as the founding director of) an U.S. National Science Foundation Industry/University Cooperative Research Center on Transportation and Electricity Convergence (focusing on electric vehicles).  He also secured substantial funding to establish, as founding director, the Network Modeling Center.

In 2003, Prof. Waller was named one of the top 100 innovators in science and engineering in the world under 35 years of age by MIT’s Technology Review magazine for his work on dynamic traffic analysis.  In 2004, he received the U.S. National Science Foundation CAREER award for his proposed research and teaching plan on adaptive network equilibrium. In 2006, he was the recipient of the Annual New Faculty Award sponsored by the Council of University Transportation Centers and the American Road and Transportation Builders Association (noting both research and teaching accomplishments).  In 2007, he was named a Fellow of the Clyde E. Lee Endowed Professorship in Transportation Engineering.  In 2008, he was named to the Phil M. Ferguson Teaching Fellowship in Civil Engineering. In addition, he received the U.S. Transportation Research Board’s Fred Burggraf Award in 2009 and the Hojjat Adeli Award for Innovations in Computing in 2012. Further, he gave the invited C.C. Mei Distinguished Lecture at MIT in 2016 and received the Pyke Johnson Award from the Transportation Research Board (a division of the U.S. National Academies) in 2019.

In the past 20 years, Prof. Waller has secured over $36m in total research funding. He has published more than 300 peer reviewed papers, supervised 35 completed PhD students and conducted over 60 funded research projects for 30 distinct sponsors worldwide.
