The urban traffic jams are daily problem in large cities. Urban Traffic Control (UTC) Systems aim to solve this problem. Because of spatial distribution of urban traffic, multiagent systems are suitable framework for implementation of UTC. In this paper, we present a new abstract model of traffic flow that and explain how a reactive control agent can be built based on it.

In order to apply environmental models successfully, it is essential to determine model parameters very carefully. A direct determination of parameter values is often not feasible since they lack a clear physical meaning or field measurements are too expensive. Therefore, estimation of parameters is usually done by fitting model response and observation in a trial and error process. Depending o...
