AlertinfraPL is a diagnosis tool devoted to heavy vehicles safety, which detects automatically dangerous areas of infrastructure. This tool considers different types of risks. The method is based on a multicriteria analysis, which aims at detecting dangerous configurations of infrastructure (i.e. combinations of geometric and surface characteristics values that may entail a risk of accident). Software based on these configurations was developed. It allows an automatic analysis of a road database containing parameters of infrastructure (radius of curvature, crossfall, longitudinal slope, unevenness, skid resistance and macrotexture) and indicates warning messages when dangerous configurations are detected. These risky configurations are called “warnings”. In a first part, the methodology applied in this study is detailed. In a second part, the warnings implemented in the diagnosis tool are described. In a last part, the validation of some warnings by statistical methods is presented.
