本文研究的是干线铁路在发生服务干扰时，枢纽和瓶颈路段的实时交通管理问题。提出了一种系统的方法，用于建模和求解交汇区和瓶颈区段的实时列车调整问题，包括列车重排序和列车重配时。提出了一个基于混合整数规划(MIP)最小化加权平均延迟(WAD)的形式化数学模型--JRM(Junction ReScheduling Model)。提出了一种基于差异进化算法的改进算法DE_JRM，用于求解基于JRM的实时列车运行计划调整问题。采用基于蒙特卡罗模拟方法的随机方法对算法DE_JRM的性能进行了评估。评估结果表明，与先到先服务(FCFS)和传统的ARS策略相比，立交桥和平坦交叉口的性能都很好。对JRM算法和DE_JRM算法进行了扩展，使之适用于铁路网瓶颈区段的实时列车调度问题的建模和求解。最后，为实现所提出的干线交汇区和瓶颈区段列车运行调整方法，提出了一个交通管理和列车运行控制一体化的系统架构。
The author of this thesis deals with the issues of real time traffic management in junction areas and bottleneck sections on mainline railways in the event of service disturbances. A systematic methodology is proposed for modelling and solving real time train rescheduling problems in junction areas and bottleneck sections, including train re-sequencing and train re-timing. A formal mathematical model, the Junction Rescheduling Model (JRM) is proposed, based on a Mixed Integer Programming (MIP) to minimise a Weighted Average Delay (WAD). An innovative algorithm based on Differential Evolution algorithm, named DE_JRM is proposed for solving real time train rescheduling problems formulated with JRM. The performance of the algorithm DE_JRM has been evaluated with a stochastic method based on Monte-Carlo simulation methodology. The evaluation results show a good performance for both flyover and flat junctions compared with First Come First Served (FCFS) and a conventional ARS strategy. The author also extends the proposed methodology, including JRM and the algorithm DE_JRM, to model and solve real time train rescheduling problems for bottleneck sections of railway networks. Finally, an integrated system architecture for the traffic management and train control is introduced for system implementation of the proposed methodology of train rescheduling in junction areas and bottleneck sections on mainline railways.
