A passenger-oriented method integrating perimeter control with bus dispatch is proposed for solving passenger dispersion problem under metro interruption. It’s essential to use perimeter control to prevent the neighborhood of the affected road network from congestion by postponing or transferring the surplus cars out of the protected area. For executing perimeter control, the theoretical tool of Macroscopic Fundamental Diagram (MFD) is used to interpret the relationship between private cars and buses which is required for transfer passengers from the targeted closed metro station. The framework based on MPC method is used to optimize the control parameters (e.g. the number of vehicles or dynamic split rates allowed to enter protected network). Furthermore, signal timing of the intersections on the boundary of protected network is studied considering the optimized split rates. Finally, the real road network around Zhujiang New Town station of Metro Line No. 5 in Guangzhou is modeled by Aimsun. A number of simulation experiments are conducted, and the efficiency of the proposed management strategy is verified by comparing with different existing strategies. To the best of our knowledge, it’s the first effort to solve passenger dispersion under subway interruption using the idea of perimeter control based on MFD.
