Determining the minimum risk route for transporting hazardous material (HM) between a point of origin and a point of destination (O-D pair) that minimizes risk to population and environment is the objective of this investigation. Southern Quebec is selected as the study area and major cities are identified as points of origin and destination on the highway network. Three classes of HM--chlorine gas, liquefied petroleum gas, and sulphuric acid--are chosen. A minimum risk route model is developed to determine minimum risk routes between an O-D pair using population or environment risk units and link impedances. The risk units for each link are calculated by considering the probability of an accident and its consequences on that link. Findings reveal that between the same O-D pair, the minimum risk routes are different for various HM. The concept of risk dissipation from origin to destination on the minimum risk route is addressed and dissipation curves are provided.
