This paper is written for the specific purpose of the International Workshop on Promotion of Technical Harmonisation on Risk-based Decision Making organised by the European Commission - DG JRC to be held between 22 and 24 May, 2000 in Stresa (Italy). Its main aim is to present personal views of the authors concerning QRA development and use. The authors have been part of an international team in charge of the development of a software dedicated to assessment of risk due to transport of Dangerous Goods (DGs) by road. They have also used the QRA software and assessed risk for real cases. Tunnels represent singularities where risk per km may be high, so special care has been taken so as to explore their contribution when a risk assessment is performed for a whole route including tunnels. Presentation will focus on QRA for transport of goods through road tunnels (by Heavy Good Vehicles : HGVs). These personal views have been also expressed by filling out a questionnaire sent to all experts attending the workshop and addressing detailed points on QRA development and use.
