The urban regional railway system has the characteristics of high network density, complicated structure, heavy passenger flow intensity and strong organization relevance, which is susceptible to emergencies such as natural disasters and equipment failure, resulting in serious loss of transportation capacity and low efficiency of transportation network. Therefore, it is urgent to study the theory and methods of train operation adjustment of urban regional railway network under special operating conditions. In this project, the propagation and dissipation mechanism of the emergency impact under the condition of composite railway network will be clarified. Also, the problems of the bottleneck identification and transfer and compensation of network capacity, and coupling optimization for train operation adjustment of urban regional railway network under special conditions will be studied. Besides, the relevant mathematics models of train operation adjustment will be proposed, and the mechanisms of reserve capacity release and residual capacity coordination transfer of urban regional railway network and constraints relaxation under special operating conditions will be designed. Furthermore, the principles and methods of the modelling of the special operating conditions for the urban regional railway network, the loss assessment and dynamic allocation of the network capacity and the integrated adjustment of the train operation will be developed in this project. In addition, the train operation simulation platform of urban regional railway will be established to form the theory and methodology of train operation adjustment in urban regional railway network under special operating conditions. The results gained from this project will provide theoretical and technical supports for urban regional railway network transportation organization and train emergency dispatching management, and further enrich the theory and technique system of railway safety operation and management in China.
