DESCRIPTION:Prof. Ramtin Pedarsani\, University of California Santa Barb
 ara\nAbstract\nIn this talk\, we propose a macroscopic model for studying 
 routing on networks shared between human-driven and autonomous vehicles th
 at captures the effects of autonomous vehicles forming platoons. We use th
 is to study inefficiency due to selfish routing and bound the Price of Ana
 rchy (PoA)\, the maximum ratio between total delay experienced by selfish 
 users and the minimum possible total delay. We find these bounds depend on
 : 1) the degree of the polynomial in the road cost function and 2) the deg
 ree of asymmetry\, the difference in how human-driven and autonomous traff
 ic affect congestion. We demonstrate that these bounds recover the classic
 al bounds when no asymmetry exists.\n \nIn the second part of the talk\, 
 we develop a model of road congestion on shared roads based on the fundame
 ntal diagram of traffic. We further design optimal routing algorithms when
  users have varying degrees of altruism. We find that even with arbitraril
 y small altruism\, total latency can be unboundedly better than without al
 truism\, and that the best selfish equilibrium can be unboundedly better t
 han the worst selfish equilibrium. We validate our theoretical results thr
 ough microscopic traffic simulations and show average latency decrease of 
 a factor of 4 from worst-case selfish equilibrium to the optimal equilibri
 um when autonomous vehicles are altruistic.\n\nBio\nRamtin Pedarsani is an
  assistant professor in the ECE department at UCSB. He obtained his Ph.D. 
 in Electrical Engineering and Computer Sciences from UC Berkeley in 2015. 
 He received his M.Sc. degree at EPFL in 2011 and his B.Sc. degree at the U
 niversity of Tehran in 2009. His research interests include machine learni
 ng\, game theory\, information and coding theory\, and transportation syst
 ems. He is the recipient of the best paper award in the IEEE International
  Conference on Communications (ICC) in 2014.
