Abstract Transportation has always been a crucial aspect of human civilization, but it is only in the second half of this century that the phenomenon of traffic congestion has become predominant due to the rapid increase in the number of vehicles and in the transportation demand in virtually all transportation modes. Traffic congestion appears when too many vehicles attempt to use a common transportation infrastructure with limited capacity. In the best case, traffic congestion leads to queueing phenomena (and corresponding delays) while the infrastructure capacity (“the server”) is fully utilized. In the worst (and far more typical) case, traffic congestion leads to a degraded use of the available infrastructure (reduced throughput that may even lead to a fatal gridlock) with excess delays, reduced safety, and, recently, increased environmental pollution.
