Dr. Waller’s Web site
Dr. Travis Waller earned his Ph.D. in industrial engineering from Northwestern University in 2000. He joined the faculty of The University of Texas at Austin in 2003. That same year, he was named one of the world’s 100 Top Young Innovators by Technology Review, MIT’s Magazine of Innovation.
Dr. Waller's research focuses on developing highly-efficient computer models and optimization techniques to improve transportation networks. Traditionally, transportation models account for steady-state traffic conditions; for example, the number of vehicles on a roadway over a 24-hour period. Waller’s research develops highly efficient approaches to using dynamic models, which can provide the number of vehicles per minute, or even second, on a roadway and are much more useful in evaluating traffic networks. Waller’s work introduced models that treat the future demand level of transportation facilities (such as roads or lanes on a road) as uncertain. This method provides a more realistic estimate of expected system performance. He has also shown that current techniques are too optimistic about future performance.
