The factors that influence highway traffic accidents and the chart of accident rate;

This paper sets up the accident model of energy release in subway fire disaster,in which the energy and dangerous substances in the subway system are regarded as the dangerous sources because their accidental release would cause fire disaster.

Based on a summary of existing accident models and an analysis of the characteristics of complex systems,a new accident model—accident rehearsal model is presented in this article.

In this paper, based on the model of accident phenomenon attributes to personal factors, the relationship between personal factors and accidents is discussed, the effect on the perception of the potential hazards made by different personal factors and the safety level of the work behaviors determined by the effect are analyzed in the condition that potential hazards exist.

Analysis of the cause of mine gas explosion countermeasures based on causal models;

Base on three factors such as evaluation methods of traffic safety,accident prediction model and safety audit,the introduction of the merits,faults and applied range of the methods and techniques can provide some references for correlative research.

It relies greatly on the accident prediction models to make effective traffic safety countermeasures.
