A simple discrete-time model of oversaturated urban traffic networks is suggested, and an optimal control problem of traffic signals during the rush hour is formulated. To solve this optimal control problem, an hierarchical optimization method is also suggested which is based upon the idea that the overall system can be decomposed into subsystems with only one input and one state by means of additional controls and equality constraints.
