Query: The Price of Anarchy in Transportation Networks: Data-Driven Evaluation
  and Reduction Strategies   Among the many functions a Smart City must support, transportation dominates
in terms of resource consumption, strain on the environment, and frustration of
its citizens. We study transportation networks under two different routing
policies, the commonly assumed selfish user-centric routing policy and a
socially-optimal system-centric one. We consider a performance metric of
efficiency - the Price of Anarchy (PoA) - defined as the ratio of the total
travel latency cost under selfish routing over the corresponding quantity under
socially-optimal routing. We develop a data-driven approach to estimate the
PoA, which we subsequently use to conduct a case study using extensive actual
traffic data from the Eastern Massachusetts road network. To estimate the PoA,
our approach learns from data a complete model of the transportation network,
including origin-destination demand and user preferences. We leverage this
model to propose possible strategies to reduce the PoA and increase efficiency.
