Federal regulations enacted in 2008 specify that railroads must determine the routings for toxic inhalation hazards, as well as for certain classes of explosives and high-level radioactive materials. These regulations require the generation of alternative routes, which are subjected to a risk assessment that considers the potential impacts on the population, the environment, landmarks, and rail operations from an accident or an act of terrorism. Any deviation from the minimum-risk route requires justification. A key challenge, therefore, is to generate routes that are cost-effective, operationally feasible and sufficiently diverse to provide substantial alternatives. These regulations have spurred the development of a complex, interrelated suite of software tools incorporating a k-alternate path algorithm, risk assessment modeling, and data archiving. This article describes the software tools.
