This paper presents a method for assessing the risk of transporting hazardous chemicals by road. The aim is to develop a user friendly computer model which can serve as an aid in the choice of transportation route. A model is presented, consisting of three parts: - estimation of the probability of a traffic accident, knowing the type of road, number of crossings, traffic load, etc.; - estimation of the probability of a tank release for each tank of interest, knowing the road type (in terms of speed limits); - estimation of the consequences of a release for each substance of interest, knowing the population density (in terms of urban, semi-urban or rural). These three parts are integrated into a computer model with a user friendly graphical interface. This means that even though the risk is estimated for each small road segment, the summation of results facilitates more comprehensive analyses. Both micro analyses (where a single transport is analysed) and macro analyses (where routes on a company or regional level are analysed) are thus possible.
