As the hazardous chemical transportation traffic accident is getting more and more serious, this paper designs a kind of active safety warning system for hazardous chemical transportation vehicle. The content of this paper mainly includes the composition and principle, establishment of theoretical model of safety distance, design of avoidance control strategy and algorithm and so on. This paper...

Today, railway operation procedures include the transportation of large amount of hazardous substances. Our research has been motivated by the desire to find concrete and urgent solutions to the safety issues of handling waste generated manly in case of accidents and disaster situations during the transportation of hazardous substances In order to ensure safety in the transportation of dangerou...

ment of the risk posed by these materials requires an understanding of how different approaches may reduce risk and their relative cost-effectiveness both alone and in combination. There are various approaches to hazardous materials transportation risk reduction. A variety of operations research techniques have been developed and applied to consider each approach individually, including conside...

In this study, we applied Bayesian networks to prioritize the factors that influence hazardous material (Hazmat) transportation accidents. The Bayesian network structure was built based on expert knowledge using Dempster–Shafer evidence theory, and the structure was modified based on a test for conditional independence. We collected and analyzed 94 cases of Chinese Hazmat transportation acciden...

Unlike widely available literatures in hazardous material (HAZMAT) transportation that basically aim at finding non dominated paths for a given origin-destination pair, our main focus in this study is on vehicle routing problem with time window (VRPTW) aspect of HAZMAT transportation problem that has received very less attention in literatures. We present a new multi-objective optimization mode...

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...

Hazardous materials are harmful to environment and human health due to their toxic ingredients. It is very important to intensify efforts in the safety management of hazardous materials, and fundamentally prevent and reduce accidents. In this study, we consider a time-dependent hazardous materials vehicle routing problem in a two-echelon supply chain system. The goal is to determine the departu...

Hazardous materials traffic originates and terminates at numerous different locations throughout the North American railroad network. Rerouting of this traffic, especially Toxic Inhalation Hazard materials, away from populated areas has received considerable attention in recent years as a means of reducing risk. However, rerouting on a route specific basis is neither simple nor necessarily effe...
