This paper addresses the application of real-time feedback route guidance to a large-scale express ring-road. The paper starts with a brief introduction of some necessary notions followed by a short presentation of the feedback routing strategy of the PI type and an ideal iterative strategy of the Frank-Wolfe type as well as of certain macroscopic freeway traffic flow modeling tools. The Amsterdam express ring-road A10 is considered for the route guidance investigation. More specifically, the introduced feedback strategy and iterative strategy are tested in simulation with regard to A10 by use of the macroscopic freeway traffic flow modeling tools. The investigation results indicate that real-time route guidance can help in reducing heavy non-recurrent congestion and in establishing dynamic user equilibrium.
