In order to improve the performance of the entire road network, and prevent the congestion transfer caused by the optimal control for a single traffic control subarea, a coordinated perimeter flow control model is proposed. The proposed model aims at two adjacent traffic control subareas. The macroscopic fundamental diagram for each of the subareas and the relationship of the inflows and outflows are considered. After describing the interaction between the two subareas by the game theory, a game-based control logic is formulated and solved to maximum the performance of the two subareas as a whole. The feasibility and benefits of the proposed control are tested by VS2010 simulation. The results show that different control strategies lead to different benefits of the two subareas. However, a stable and efficient operation situation could be obtained by multiple gaming. Moreover, the subarea with lower network capacity may deserve more protection. The inflow should be controlled when its number of internal vehicles reaches the optimal value.
