Abstract
The paper addresses real-time feedback route guidance in large-scale urban express ring-roads. Feedback routing strategies of bang-bang, P, and PI types as well as an ideal iterative strategy of the Frank-Wolfe type are applied to this end, with the aid of the macroscopic traffic modelling tools METANET and METANET-DTA. The investigation results indicate that real-time route guidance can help alleviate and dissolve heavy non-recurrent congestion, and establish dynamic user equilibrium.
