Freight-train derailment rates for railroad safety and risk analysis

Liu, X., M.R. Saat and C.P.L. Barkan. 2017. Freight-train derailment rates for railroad safety and risk analysis. Accident Analysis and Prevention. 98 (2017): 1-7. doi:10.1016/j.aap.2016.09.012.

Derailments are the most common type of train accident in the United States. They cause damage to infrastructure, rolling stock and lading, disrupt service, and have the potential to cause casualties, and harm the environment. Train safety and risk analysis relies on accurate assessment of derailment likelihood. Derailment rate – the number of derailments normalized…

Risk-based optimization of rail defect inspection frequency for petroleum crude oil transportation

Liu, X. and C.T. Dick. 2016. Risk-based optimization of rail defect inspection frequency for petroleum crude oil transportation. Transportation Research Record: Journal of the Transportation Research Board. 2545: 27-35. doi:10.3141/2545-04.

The rapid expansion of production of North American petroleum crude oil from shale has led to a significant increase in rail transport of crude oil. Broken rails are frequent causes of train accidents. Ultrasonic rail defect inspection is widely used to prevent train accidents caused by broken rails, thereby reducing the hazardous materials transportation risk.…

Safety effectiveness of integrated risk reduction strategies for rail transport of hazardous materials

Liu, X., M.R. Saat and C.P.L. Barkan. 2013. Safety effectiveness of integrated risk reduction strategies for rail transport of hazardous materials. Transportation Research Record: Journal of the Transportation Research Board. 2374: 102-110.

Railroad transportation plays a critical role in safely and economically moving hazardous materials throughout North America. Effective management of the risk of hazardous materials transportation is a high priority of both the American rail industry and government. A number of strategies and technologies have been implemented or are being developed to reduce this risk. Each…
