Abstract:

In this paper, stability analysis of traffic control for two-region urban cities is treated. Two Macroscopic Fundamental Diagrams (MFDs) system for two regions is defined. Under the assumption of triangle MFDs, and two traffic demands: exogenous and endogenous demands, the two-region MFDs system is modeled as a piecewise second-order system. Necessary and sufficient conditions are derived for stable equilibrium accumulations in the undersaturated regimes for both MFDs. Moreover, the traffic perimeter control problem for the two-region MFDs system is formulated. Phase portraits and stability analysis are conducted, and new algorithm is proposed to derive the boundaries of the stable and unstable regions. Based on these regions, a state-feedback control strategy is derived. Few numerical examples are presented.
