Summary

An online control strategy for route diversion via variable message signs (VMS) in freeway networks is presented. The control task is formulated as a dynamic, nonlinear, discrete-time optimal control problem with constrained control variables and is solved at each control interval by gradient based search. The proposed search algorithm considers directly the binary nature of the control signals. As a prerequisite, a macroscopic state-space description of the network traffic dynamics is presented. Simulation results for route diversion in a complex real example network are provided
