However, the effect of route choice behavior on MFD modeling and control in case of heterogeneous urban networks, where different parts of the city are subject to different types of control, is still unexplored. This paper advances in this direction by introducing two MFD-based traffic models with different levels of vehicle accumulation state and route choice behavior aggregation. This configuration enables to integrate limited traffic state observability and scrutinize implications of drivers route choice in performance of control strategies. The paper investigates the user equilibrium and system optimum traffic conditions in a multi-subregion network, where the traffic modeling is based on MFD. In the aggregated route choice framework drivers are allowed to cross regions of the city multiple times, which was a constraint in previous models. In addition, a route guidance advisory control system is proposed as a large-scale traffic management strategy. The results show that the route guidance system reduces the total urban delay by 10.6%, while the maximum improvement in case of system optimum condition is 13.6%.
