With the characteristics of high speed, heavy density and strong dependence on control equipment, safe high-speed
railway operation are affected by various factors whose interaction relationships resulted in the complexity and high risks
of high-speed railway. To adopt 'basic theory, key technology and simulation experiment' method, based on the
"proactive safety" concept, a visual, intelligent and integrated monitoring and early-warning platform for safe high-speed
railway operation was proposed in this paper, and was described from objectives, architecture and functions, to achieve
comprehensive monitoring, safety warning, decision support and information transfer and sharing in the whole operation.
In order to prevent accidents and improve the safety level of the railway operations, based on the statistical analysis
of railway operation accidents at home and abroad over the years, the safety factors set of railway operation was built in
the paper by researching the evolution laws of human, equipment, environment and management in railway transport
system. And then, through analyzing the interaction relationships of safety factors from the systematic view, a network
which reflected the complex interaction relationships between the safety factors was established, and based on ISM
(Interpretative Structural Modeling) method, a hierarchical structure model of safety factors of railway operation in
which the complex interaction relationships were divided hierarchically as to explain the deep causes of the railway
accidents, then a comprehensive safety factors system of railway operations was established, in order to control and
prevent the railway operation accident, to lay the foundation for quantitative analysis and prediction of railway operation
accident, and to guide the scientific safety management of railway operation.
The traditional safety evaluation of urban rail transit operation was limited to the station or line, not from the
perspective of the whole network operation safety. Specific to the characteristics of the urban rail transit network operation
in the new situation, based on complex network theory, the urban rail transit network model was established, and the
formalized description of the network model was given. Based on above, from the passenger traffic, environment and other
aspects, the safety evaluation index of urban rail transit network operation was established, which included hidden trouble
indexes, accident indexes and safety economic index, aiming at to provide support for overall safety evaluation.
