Optimal freeway network control via route recommendationOptimal freeway network control via route recommendation Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-211994enAn 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.
