material shipments (10–14). Rerouting hazardous materials shipments with the objective of reducing risk is complex because of the many variables that interact to affect risk. Quantitative risk analysis (QRA) of hazardous material transportation dates to the 1970s. Although advances in methodology continue, QRA has matured to the point that it is an effective tool and has been used to inform dec...

In this paper, we propose toll-setting as an alternative policy tool to regulate the use of roads for dangerous goods shipments. We propose a mathematical formulation as well as a solution method for the hazardous materials tool problem. Based on a comparative analysis of proposed mathematical models, we show that toll policies can be more effective than the popular network design policies that...

Railroads in North America have recently come under pressure to avoid transporting certain high hazard materials through metropolitan areas. There are two principal reasonsfear of terrorist attack and concern about the risk of an accident-caused release. Consequently, a number of municipalities are considering legislation to block hazardous materials transportation through their communities, th...

The aim of this research was to investigate accidental releases of ammonia followed by an en-route incident in an attempt to further predict the consequences of hazardous cargo accidents. The air dispersion model Areal Locations of Hazardous Atmospheres (ALOHA) was employed to track the probable outcomes of a hazardous material release of a tanker truck under different explosion scenarios. The ...

In 1998 the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) launched the Convention Project on Chemical Safety in developing countries. The project aims to support developing countries in the implementation of the Rotterdam and Stockholm Conventions, create human resources and institutional capacities and to demonstrate via pilot measures how chemical safety in the partner countries c...

The current literature in the rail–truck intermodal transportation of hazardous materials (hazmat) domain ignores congestion at intermodal yards. We attempt to close that gap by proposing a bi-objective optimization framework for managing hazmat freight that not only considers congestion at intermodal yards, but also determines the appropriate equipment capacity. The proposed framework, i.e., a...
