With the current high rate of contagiousness and infection from Omicron, we have made the decision to conduct all January classes remotely and to require, with limited exceptions, all employees without essential on-campus duties during this period to work from home through January 28th.  For more information on Covid-19 and the start of spring semester, please use this link to our Covid Response page.

Overcrowded traffic in transportation networks

Professor Anita Raja and Eliyahu Friedman (EE'16) co-author paper with Mohammad Hasan, Ana Bazzan titled "A Multiagent Solution to Overcome Selfish Routing In Transportation Networks" that was accepted to the IEEE 19th International Conference on Intelligent Transportation Systems (ITSC 2016), Rio De Janeiro Brazil.


It  is  well-known  that  selfish  routing,  where  individual  agents  make  uncoordinated  greedy  routing  decisions,does  not  produce  a  socially  desirable  outcome  in  transport and  communication  networks.  In  this  paper,  we  address  this general  problem  of  the  loss  of  social  welfare  that  occurs  due to uncoordinated behavior in networks and model it as a multiagent  coordination  problem.  Specifically  we  study  strategies to  overcome  selfish  routing  in  traffic  networks  with  multiple routes where a subset of vehicles are part of a social network that exchanges traffic related data. We investigate classic traffic flow paradoxes that are ubiquitous in various types of networks leading  to  severe  congestion.  We  present  a  novel  distributed traffic coordination algorithm that alleviates congestion by harnessing the real-time information available through the driver’s online  social  network.  We  also  propose  a  utility  computation mechanism for route choice that generates near-optimal flows.Our extensive simulation results show that social network based multiagent traffic route coordination contributes to mitigate the effects of these paradoxes and significantly reduces congestion

  • Founded by inventor, industrialist and philanthropist Peter Cooper in 1859, The Cooper Union for the Advancement of Science and Art offers education in art, architecture and engineering, as well as courses in the humanities and social sciences.

  • “My feelings, my desires, my hopes, embrace humanity throughout the world,” Peter Cooper proclaimed in a speech in 1853. He looked forward to a time when, “knowledge shall cover the earth as waters cover the great deep.”

  • From its beginnings, Cooper Union was a unique institution, dedicated to founder Peter Cooper's proposition that education is the key not only to personal prosperity but to civic virtue and harmony.

  • Peter Cooper wanted his graduates to acquire the technical mastery and entrepreneurial skills, enrich their intellects and spark their creativity, and develop a sense of social justice that would translate into action.
