Title: How connected vehicles can increase throughput and decrease delay on urban roads Speaker: Prof. Pravin Varaiya, UC Berkeley

Abstract: Intersections are the bottlenecks of the urban road system because an intersection’s capacity is only a fraction of the vehicle flows that the roads connecting to the intersection can carry. The saturation flow rate, and hence the intersection’s capacity, can be doubled if vehicles can cross intersections in platoons rather than one by one as they do today. Platoon formation is enabled by connected vehicle technology. Doubling the saturation flow rate has dramatic mobility benefits: the throughput of the road system can be doubled, or vehicle queues and delay at intersections can be halved. These predictions draw on an analysis of a queuing model of a signalized network with fixed time control and they are validated in a simulation of a small urban network with 16 intersections and 73 links.

Speaker Biography: Pravin Varaiya is Nortel Networks Distinguished Professor in the Department of Electrical Engineering and Computer Sciences at the UC Berkeley.

From 1975 to 1992 he was also Professor of Economics at Berkeley. From 1994 to 1997 he was Director of the California PATH program, a multi-university research program dedicated to the solution of California's transportation problems.

Varaiya has held a Guggenheim Fellowship and a Miller Research Professorship. He received Honorary Doctorates from L'Institut National Polytechnique de Toulouse and L'Institut National Polytechnique de Grenoble, and the Field Medal and Bode Lecture Prize of the IEEE Control Systems Society. He is a Fellow of IEEE, a member of the National Academy of Engineering, and a Fellow of the American Academy of Arts and Sciences.

He is on the editorial board of "Discrete Event Dynamical Systems" and "Transportation Research---C". He has co-authored three books and over 300 technical papers. The second edition of High-Performance Communication Networks (with Jean Walrand and Andrea Goldsmith) was published by Morgan-Kaufmann in 2000. Structure and Interpretation of Signals and Systems (with Edward Lee) was published by Addison-Wesley in 2003.
