NSF-GREEN CITY PROJECT (2011-2014) Closing the loop between traffic/pollution sensing and vehicle route control using traffic lights and navigators UCLA M.Gerla, G.Pau (CS), B.Taylor (P.Policy), S. Paulson (Atmos) Rutgers University L. Iftode, B. Nath (CS)

The Vehicle Transport Challenge Safety 33,963 deaths/year (2009) 5,800,000 crashes/year Leading cause of death for ages 4 to 34 Mobility 4.2 billion hours of travel delay $78 billion cost of urban congestion Environment 2.9 billion gallons of wasted fuel 22% CO2 from vehicles

The Connected Vehicle Program DOT solution => vehicular communications Wireless is now at the cross section of several complex systems: Wireless communications and spectrum Vehicular traffic (routing, congestion fees..) Public Transport System Atmospheric pollution model Power distribution grid (electric cars, etc) Driver Behavior and Social Networking

The wireless opportunity Exploit wireless Interaction among systems Look at system as a whole instead of separate components => stable solutions, avoid pitfalls Example 1: Better (eco) routes reduce accidents, pollution, congestion, time waste, fuel waste Example 2: V2V communications help discover and solve local traffic congestion problems In all cases, wireless channel “closes the loop

Methods of Attack Fluid flow models Atmospheric models Cellular automata; stochastis models Hierarchical Models Convex multicommodity optimization Game theoretical optimization Control theory Cognitive Radios; spectrum allocation Simulation, Emulation, small scale testbeds
