ASSESSING THE RISKS ASSOCIATED WITH THE TRANSPORT OF DANGEROUS GOODS BY TRUCK AND RAIL USING THE RISKMOD MODEL

To provide an objective tool for assessing the risks involved in the transport of dangerous goods, a model called RISKMOD-1 was developed for Transport Canada by the Institute for Risk Research. The model implements the computational aspects of a comprehensive risk assessment methodology which addresses both the quantitative and qualitative aspects of dangerous goods releases following a transport incident. This paper describes the model's implementation, data requirements, and outputs. The risk assessment model consists of an analysis of link-specific accident rates and a fault tree analysis to determine the probability of a dangerous goods release of a particular type. In parallel, a series of commodity-specified damage models compute the impact areas associated with representative sizes and types of releases. The impact areas for each damage threshold are then multiplied by the population density and property exposure along each link to determine the total risk associated with a dangerous goods shipment that uses the link. This estimate of total risk can optimally be further converted into a risk cost value in monetary terms and summarized for the entire route. Both the risk and risk cost estimates are intended to be used in conjunction with other subjective analyses and performance measures to provide a comprehensive decision-making aid for risk managers.
