Abstract: Congestion in transport networks is a topic of theoretical interest andpractical importance. In this paper we study the flow of vehicles in urbanstreet networks. In particular, we use a cellular automata model to simulatethe motion of vehicles along streets, coupled with a congestion-aware routingat street crossings. Such routing makes use of the knowledge of agents abouttraffic in nearby roads and allows the vehicles to dynamically update theroutes towards their destinations. By implementing the model in real urbanstreet patterns of various cities, we show that it is possible to achieve aglobal traffic optimization based on local agent decisions.
