Risk Analysis of Crowded Stampede Accident in Subway Stations Based on DEA Method
摘要
Abstract
Many potential safety hazards exist in metro operation due to short operating time, big traffic, and incomplete management system and so on. The security risks caused by the crowded stampede accident are particularly acute. The data envelopment analysis ( DEA ) is used to quantitatively analysis the crowded stampede risk. According to the data of ten subway stations in Wuhan metro system, efficiency analysis in terms of technical efficiency, scale reward and comprehensive efficiency is concluded. Based on this, by determining each decision-making unit’ s slack variable modifier, the improvement strategies are subsequently made, and the main factors are identified. Results indicate that the crowded stampede accident risk assessment is consistent with actual situation. Thus, DEA method can be used in determining the crowded stampede risk status in the station, as well as making improvement strategies.关键词
