Outline
As urban rail transit networks continue to expand, junction areas in cross-line operations have increasingly become critical bottlenecks limiting capacity improvement. To alleviate passenger congestion during peak hours, this paper proposes a virtually coupled train coordination and scheduling method that incorporates passenger service level considerations. A train dynamics model is first established based on traction-braking characteristics and state transition rules. Then, a passenger- oriented Nash equilibrium game framework is constructed by introducing passenger priority levels to achieve coordinated optimization of train operation strategies. Furthermore, a bi-objective optimization function is formulated to balance two key indicators: passenger travel time and platform crowding. Finally, taking the junction area of Chongqing Rail Transit Lines 4, Loop Line, and Line 5 as the research object, eight typical operation scenarios are constructed to conduct simulation verification of the virtual coupling strategy, moving block strategy, and First Come First Serve (FCFS) strategy, and the impact of passenger flow changes on optimization effectiveness is analyzed. Simulation results demonstrate that, under peak operating conditions, the proposed method reduces passenger travel time cost by approximately 3% and platform congestion by around 30% compared to the traditional First Come First Serve (FCFS) strategy and the moving block-based game approach, significantly enhancing transportation efficiency and passenger satisfaction in cross-line operation zones.
