This paper considers the effect of train speed on railroad hazardous materials transportation risk. A statistical method was developed to estimate the speed-dependent conditional probability of release (CPR) of tank cars involved in accidents with the objective of assessing its effect on risk analysis results. A case study of a representative hazardous materials route was conducted in which ris...

Traffic accident data include multidimensional dynamic and static factors such as “people, vehicles, roads, environment” at the time of accident, which is one important sources for improving traffic safety environment. Based on case accidents construction idea knowledge graph, demand, modeling, extraction, storage are analyzed in detail. Finally, graph constructed. The visualization analysis ca...

Abstract To reduce the hazards of collapse accidents in construction process and to ensure that lives, health, property workers are protected, this study used theory safety system engineering identify accidents, analyze hazards, predict consequences, evaluate systemic risks, effects improve them. At same time, risk factors were evaluated qualitatively quantitatively by using analysis methods fa...

Identifying accident precursors using real-time identity information has great potential to improve safety performance in construction industry, which is still suffering from day to day records of accident fatality and injury. Based on the requirements analysis for identifying precursor and the discussion of enabling technology solutions for acquiring and sharing real-time automatic identificat...
