Analysis of Causes of Railway Traffic Safety Accidents Based on Grounded Theory
Download as PDF
Through the traversal of the hazard log and the application of grounded theory to mine text data, the three-level coding process discovers the causes of accidents above the higher risk level of the railway, and summarizes various factors theoretically, connecting the theory into a “story line” and establishing Two theoretical lines of factors were analyzed, and the core theory was found to be based on the safety management system. The theoretical line model explains the layers of causes from system to technology to human factors that lead to frequent railway accidents.
