Pravin Varaiya

Can VANETs reduce congestion?
Professor Pravin Varaiya
Department of Electrical Engineering and Computer Science
University of California, Berkeley

Congestion is caused by incidents, special events, poorly managed highways, adverse weather, and excess demand.  The delays caused by these causes will be discussed, using data from California.  An effective congestion management strategy consists of a set of action plans targeted at the different causes of congestion.  The talk will explore the potential role of VANETs within such action plans, focusing on communication, sensing, and signal processing requirements.  .

Pravin Varaiya is Nortel Networks Distinguished Professor in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley.  From 1975 to 1992 he was also Professor of Economics at Berkeley.  His current research is concerned with communication networks, transportation, and hybrid systems.

Varaiya has held a Guggenheim Fellowship and a Miller Research Professorship.  He received an Honorary Doctorate from L’Institut National Polytechnique de Toulouse, and the Field Medal of the IEEE Control Systems Society.  He is a Fellow of IEEE and a member of the National Academy of Engineering.  He is on the editorial board of several journals, including Discrete Event Dynamical Systems and Transportation Research---C. He has co-authored three books and more than 250 technical papers.  The second edition of High-Performance Communication Networks (with Jean Walrand) was published by Morgan-Kaufmann in 2000.  “Structure and Interpretation of Signals and Systems” (with Edward Lee) was published in 2003 by Addison-Wesley.
