An important issue in Hazardous Material (hazmat) transportation risk assessment is to evaluate the probability bounds of accidents occurrence, whose values are difficult to be estimated due to its low frequency and the related lack of statistical data. This paper presents an original approach to integrate uncertainty in the quantitative analysis of hazmat transportation accidents. The proposed...

The purpose of this study was to systematically investigate hazardous materials (hazmat) releases and determine the mechanisms of these accidents, and the industries/activities and chemicals involved. We analyzed responses by Massachusetts' six district hazmat teams from their inception through May 1996. Information from incident reports was extracted onto standard coding sheets. The majority o...

Today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchers due to the risk of this transit, which should be considered for development of industries and transportation. Therefore, a model that is useful should consider the risk and damage to humanitarian and environmental issues due to transit of hazmat materials. By considering the related cost, the r...

1 The hazmat network design problem (HNDP) aims to reduce the risk of transporting hazmat in the 2 network by enforcing regulation policies. The goal of reducing risk can increase cost for different 3 hazmat carriers. Since HNDP involves multiple parties, it is essential to take the cost increase of all 4 carriers into consideration for the implementation of the regulation policy. While we can ...

The U.S. Department of Transportation (DOT) Office of Hazardous Materials Safety estimates that an average of over 800,000 shipments of hazardous materials (HAZMAT) are made each day in the United States [27]. The DOT also reports that approximately 1.5 billion tons of hazardous materials are shipped each year [26]. The majority of the hazardous material shipped is classified as flammable liqui...

This paper focuses on the effects of weather systems on hazmat routing. We start by analyzing the effects of a weather system on a vehicle traversing a single link. This helps characterize the time-dependent attributes of a link due to movement of the weather systems. This analysis is used as a building block for the problem of finding a least risk path for hazmat transportation on a network ex...
