Optimizing Railroad Tank Car Safety Design to Reduce Hazardous Materials Transportation Risk
I develop a modeling approach in which tank car safety design optimization is considered as a two-phase process. The first phase addresses the tradeoff between safety and transportation efficiency by using Pareto optimization to identify the most efficient design combinations to improve safety …

Quantitative analyses of unit train safety and railroad tank car implementation policy
Railroads play a critical role in the transportation and economic prosperity of North America. Train safety has improved considerably over the past decade. However, with the large volume of traffic, accidents still occur. Derailments are the most common type of train accident recorded in the …

Modeling the impact of petroleum mixtures released from railroad tank car accidents on groundwater contamination and cleanup times
… of nonaqueous phase liquids released due to railroad tank car accidents. The properties include density, viscosity, surface and interfacial tension. Several models are used to predict pure compounds properties, similar mixture properties, and dissimilar mixture properties. Models for …
