The Mutual Feed Response Model of Typical Disturbance and Dispatch Command in High-Speed Railway Express

As an important component of the comprehensive transportation system, high-speed railway has the characteristics of large transportation capacity, fast punctuality, efficient and convenient. In recent years, high-speed railway freight has also been booming. With the continuous increase of the scale of high-speed rail network and train operation density, the probability of various random internal or external disturbances in the high-speed rail system is also greatly increased, resulting in train delays in emergencies, and thus affecting the safe and stable operation of the entire railway system. Based on the typical disturbance library, the dispatch and command mutual feed-response model based on the spatio-temporal network is constructed to reveal the spatio-temporal evolution law of the high-speed railway operation network and realize the spatio-temporal prediction of delays under different typical emergencies, which provides theoretical and technical support for reducing the negative impact of emergencies and improving the elasticity of schedule. It has important theoretical and practical significance to ensure the smooth and safe operation of high-speed railway.
