英文摘要: In this proposal, we propose models and algorithms for the integration of traffic regulation and train control to reduce train delays and energy consumption for urban rail transit systems. A microscopic module and a macroscopic module will be formulated for the infrastructure, e.g., track layout, stations and signaling, of urban rail transit systems. Based on the analysis of the relationship between the running time and the energy consumption, train speed profiles and control policies for the train operation levels will be optimized with the objectives of the integration of traffic regulation and train control. In addition, the applicable ranges and boundary conditions of these train operation levels will be determined. The train flow evolution under stochastic perturbations will be conducted for urban rail transit systems. A timetable deviation and conflict detection algorithm and a conflict resolution and traffic regulation algorithm will then be presented based on the prediction of train running times and dwell times. Moreover, a closed-loop optimization framework is built for the integration of traffic regulation and train control in urban rail transit systems. The consistency of the traffic regulation and the effect of the prediction length will be investigated. This study is significant for the research on traffic regulation and train control. In addition, it will provide important theoretical guidance and economical benefit to our urban rail transit systems.
