  • IFSTTAR - PhD

    CHAMPS SUR MARNE 2015 - maintenant Project: Modèle de Risque Pour les PAssages à Niveau (Partners: SNCF, Railenium, IFSTTAR).
    MoRiPAN aims to establish a risk model for French Level Crossings. The project starts from a thorough analysis of accident/incident statistics at level crossings to elaborate a preliminary model that allows to retrace risk at level crossings. Then based on this preliminary analysis, a Bayesian model will be developed to identify and quantify the safety impact of a variety of parameters. The last phase of the project consists in a validation phase.
    Obtaining such risk model helps to make a thorough and trustworthy diagnosis pertaining to level crossing safety, and thereby to efficiently focus the effort and investment on the potentially riskiest cases (among the 18000 level crossings in France)
