A network-wide anticipatory control of an urban network using macroscopic fundamental diagram

In this paper, a network-wide anticipatory control (AC) framework, incorporating drivers' route choice behaviour, is proposed. The proposed AC, consisting of two main levels of control and route choice, explicitly accounts for road users' responses to the implemented control. Perimeter control, modelled in an MPC framework for real-time applications, optimizes inter-regional transferring flow at the network level. User equilibrium is established through a logit route choice model and solved using the method of successive averages (MSA). The modelling approach adopted is based on macroscopic fundamental diagram (MFD), which provides a unimodal low-scatter relationship between density and outflow of any region within a network. Numerical results indicate that the proposed AC outperforms no control and basic control cases and shows promising results in alleviating congestion and deriving the network to near-system optimum traffic condition, under various demand patterns and levels.
