BG Chosen to Develop QRA Model

Published on 26.07.2017

The Quantitative Risk Assessment (QRA) model of the World Road Association assesses risks related to the transport of dangerous goods on roads, whether on open-air sections or in tunnels.

QRA is a risk assessment tool developed by the World Road Association, also known by the acronym PIARC (Permanent International Association of Road Congresses). By providing a quantified assessment of road-related risks, QRA is useful in comparing itineraries or correlating data with acceptability criteria. It is operational in many countries, notably in the European Union, where it has become a benchmark.

The model requires the acquisition of significant amounts of data on traffic (all vehicles, in particular those transporting dangerous goods), road characteristics (geometry, speed, tunnel-section parameters), accidentology, neighbouring populations and weather conditions, etc.

The model, which was developed in the late 1990s, has not been upgraded in over ten years. As a result, it functions only with older versions of Windows and Excel that are almost non-existent today. PIARC mandated BG to revamp the software so that it can run on the most recent platforms (Windows 10 and Excel 2016).

Development work for the new QRA version began this summer, for delivery to PIARC in 2018.
