| Abstract: | This paper presents a model of propagation dynamics to study the law of emergency spreading on the network of high speed railway (HSR) and explore its propagation process, combining with an analysis of topological structure characteristics. The theory of complex network is applied to construct the HSR physical network and HSR transportation network respectively, and relevant statistical characteristics indicators under complex network conditions are calculated to determine the type and nature of HSR networks. Meanwhile, based on the nature of HSR networks, a model of emergency train delay on the network is established considering propagation dynamics. The delay propagation and diffusion process has been discussed at different parameter values, and related measures and strategies are provided to control the delay spreading of emergency in the HSR network. |
