A method for the fixed-time signal traffic light control problem is proposed for large metropolitan areas. Its characteristics are: a multiobjective formulation focusing on desired offsets, a hierarchical structure derived from the problem in order to reduce complexity and an interactive strategy for implicitly assessing a performance measure. The core of the method is a mathematical model for scheduling periodic phenomena.
