This morning, I continued with the literature review. I wanted to get a better understaing on how the speed of the train affects the overall risk so I started the day off by reading Barkan, C. P. L., Dick, C. T. & Anderson, R., 2003. Railroad Derailment Factors Affecting Hazardous Materials Transportation Risk, Washington, D.C.: Transportation Research Record: 1825. Paper No. 03-4429. In this article, the FRA accident data for the period 1992-2001 is analyzed to determine and understand first what are the most frequent and severe accidents and second what are the factors affecting hazardous materials transportation risk. One of the most significant conclusions is that the speed and number of cars derailed significantly relate to hazardous materials release probability.
Later, I read Saat, M. R. & Barkan, C. P., 2005. Release Risk and Optimization of Railroad Tank Car Safety Design, Washington, D.C.: Transportation Research Record: Journal of the Transportation Research Board, No. 1916: 78-87. In this study a new metric for quantifying hazardous materials releases is developed and applied to evaluate tank car thickness and safety. It is determined that the rate of release and thus the quantity of release depend on the size of the puncture, the tank’s internal pressure, and the viscosity of the commodity. At the end of the document, the trade-off between reduced release probability and increased accident exposure with increased tank thickness is discussed and an optimization of this trade-off is presented.
After lunch I talked to Xiang as I have some questions regarding the procedure and methodology he wanted me to follow to do the analysis he assigned me. I worked on it for the rest of the day and I plan to finish it by Monday.
-Literature review on Railroad Hazmat Transportation (to be finished)
-Gather and edit information Xiang requires for his research (to be finished)
Next day:
-Understand the reasons for the rise of crude oil transportation by rail
-Find key origins and destinations of this transportation.
-Gather and edit information Xiang requires for his research
-Literature review on Railroad Hazmat Transportation
