Regional Average Speed Limit Control in Urban Networks

Large-scale urban road traffic control specifies a challenging problem. Macroscopic fundamental diagram (MFD) of urban traffic enables the derivation of aggregated dynamical models of city-scale traffic, which can be used for model-based control design. As an alternative to the perimeter control actuation method commonly used in MFD-based control, in this paper the authors propose actuation over regional space-mean speeds. This actuation method considers that the regional speed can be restricted via instrumentation similar to variable speed limits in freeways, or vehicle-to-infrastructure communication. The authors develop model predictive control schemes considering actuation over regional speeds and perimeter control, and compare their performances via simulation with a congested scenario. The results suggest that the proposed scheme has potential both as an alternative or as a complementary method to perimeter control-based actuation.
