文摘The steady-state or cyclic control problem for a simplified isolated traffic intersection is considered.The optimization problem for the green-red switching sequence is formulated with the help of a discrete-event max-plus model.Two steady-state control problems are formulated:optimal steady-state with green duration constraints,and optimal steady-state control with lost time.In the case when the criterion is a strictly increasing,linear function of the queue lengths,the steady-state control problems can be solved analytically.The structure of constrained optimal steady-state traffic control is revealed,and the effect of the lost time on the optimal solution is illustrated.
