Safety of Dangerous Goods Transportation by Road: a Comparison Between QRAM and GIIS Software

The aim of the work is to develop a comparison between two software able to assess the risk associated with the transport of goods by road: QRAM - Quantitative Risk Assessment Model and GIIS – Global Integrated Information System, implemented within the DESTINATION project - DangErous tranSport To New prevenTive Instruments. It was thus possible to verify if the outputs obtained with the two software are comparable, although the two analytic models are widely different. The analysis included two comparisons, α and β: the former considers road users as targets and two accident scenarios, i.e. the petrol pool fire and the Liquefied Petroleum Gas (LPG) jet fire. The latter concerns three accident scenarios, i.e. the petrol and LPG Vapor Cloud Explosion (VCE) and the ammonia release. In this case, road users and population are taken into consideration as targets: residents, industry workforce, tourists and staff of commercial, health and education facilities. The assessment was carried out on different types of road: highway, state road and provincial roads, in order to study the functioning of the two models with different traffic conditions and exposed population (targets) surrounding the road links.
