Abstract

This study develops a quantitative risk assessment (QRA) model to evaluate the hazmat transportation accident risk that combines the frequency and consequence of all possible accident scenarios. The possible accident scenarios are identified by an event tree comprising six intermediate events including accident time, wind speed, number of vehicles involved in the accident, leak hole size, incapacitating injury/death of the hazmat truck driver and time of exposure to toxic gas. A mathematical model is presented to evaluate the quantitative consequence in terms of the number of fatalities for each accident scenario. With the hazmat transportation relevant data in Shanghai, one case study is finally created to testify the capability of the proposed QRA model in evaluating the hazmat transportation accident risk.
