We study the problem of finding hazmat road transportation paths minimizing both the total risk of hazmat shipments and the total transportation cost, meanwhile guaranteeing a certain level of risk equity over the population. To ensure the selection of a set of paths that also guarantee an equitable spread of the risk over the population, we introduce a new similarity index. The problem is math...

Despite significant advances in risk management, routing hazardous materials (hazmat) has relied on relatively simpler methods. In this paper, we formally introduce an advanced risk measure, called conditional valueat-risk (CVaR), applied to truck routing problems for hazmat transportation. We find that CVaR offers a flexible, risk-averse, and computationally tractable routing method that is ad...

today, transportation of hazardous materials (i.e., hazmat) is a very important issue for researchersdue 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 humanitarianand environmental issues due to transit of hazmat materials. by considering the related cost, thereali...

In this paper, we propose a dual toll pricing method to mitigate risk of hazardous materials (hazmat) transportation. We aim to simultaneously control both regular and hazmat vehicles to reduce the risk. In our model, we incorporate a new risk measure to consider durationpopulation-frequency of hazmat exposure. We first formulate the model as a Mathematical Program with Equilibrium Constraints ...

In this work we consider the following hazmat transportation network design problem. A given set of hazmat shipments has to be shipped over a road transportation network in order to transport a given amount of hazardous materials from specific origin points to specific destination points, and we assume there are regional and local government authorities that want to regulate the hazmat transpor...

Singapore is the third largest oil-refining centre in the world, with a large petrochemical hub located at Jurong Island. In view of the increasing concern for transportation security, there is an urgent need to improve the way trucks carrying hazardous materials (HAZMATs) are being routed on urban and suburban road networks. Routing of such vehicles should not only ensure the safety of travele...

Safety and emergency response are being given greater importance while planning infrastructure and transportation projects. This is particularly so, when transporting hazardous materials HAZMAT within a heavily urbanized area such as Singapore. The number and location of fire stations significantly influence the efficiency of emergency response during fire accidents. This paper presents an appr...

Road selection for hazardous materials transportation relies heavily on risk analysis. With risk being generally expressed as a product of the probability of occurrence and the expected consequence, one will understand that risk analysis is data intensive. However, various authors have noticed the lack of statistical reliability of hazmat accident databases due to the systematic underreporting ...
