Quantitative risk assessment of hazardous materials during road transportation with accident causation models

Abstract

Transport operations of hazardous materials have greater risks during the entire stretch of transportation. Even if low frequency and high impact incidents are reported, it has caused in significant human loss in the industry. Environmental damage also is very high. But, every accident is associated with different type of failures with different root causes. An analysis of the pattern of accidents and occurrence of incident with root causes can act proactively to prevent or to reduce loss or damages. A number of incidents involving the release of toxic chemicals are reported leading to serious consequences during the transportation of Hazardous Materials. Most of the hazards can be eliminated or limited to a minimum through the use of risk analysis. A powerful tool like Transportation Risk Analysis can be used to select the most suitable alternative with a reduced risk. The various risk components like frequency, risk scenario, risk consequence, and likelihood are to be properly mapped with the selected route to obtain the best output. But due to the changes in urbanization, the characteristics of the neighbourhood of selected route are changing, resulting in a serious consequence.
