In order to meet the need of promoting railway emergency disposal capacity, the decision making process of railway emergency management integrated with decision support systems(DSS) was applied to develop a railway emergency intelligent decision support system(REIDSS) for preventing and reducing disasters in railway industry. This paper firstly presented the definition and objective of REIDSS. Then...
Time-frequency analysis is the important tool in signal processing, especially for non-stationary signals. When the interesting signals contaminated by impulsive noises, conventional time-frequency analysis method degenerate seriously because of lacking of limited second moment. In order to solve the degeneration of the estimation algorithm under non-Gaussian impulsive noise environment, the improved...
This paper proposed approach of integrating supervision alarms and trains located on the map to support emergency management of urban rail transit network. The characteristics of dynamic passenger flow are analyzed to figure out transfer coordination and evacuation schema, related algorithm is developed. Information sharing is discussed and method of connection timetable optimization for metro and...
with the rapid development of high-speed railway, China has become the world's largest number of high-speed railway tunnels. Many researches focus on quantitative assessment of design and construction stage for tunnel safety. The researches about quantitative assessment of integrating all factors for safe operation of the tunnel are few. Based on this, this paper analyzes factors of effecting tunnel...
