Evaluation de l'impact d'un futur remblai de la ligne à Grande Vitesse Est Européenne sur le risque de gel dans le vignoble de Champagne
2002
In order to evaluate for the vineyard, the additional risk of freezing, which could be generated by a railway embankment of the High Speed Line (TGV «Paris-Strasbourg») a canvas cover of the future embankment (length 480 m, height 3 m maxi) was drawn up in the bottom of a wineyard slope. Measurements of Actinothermal Index (AI) Temperatures, at the height of the bud (at 50 cm of the surface) and measurements of of cold air windslopes, were carried out on a microclimatic scale. We recorded 19 points of measurements, without then with the presence of the canvas cover, for the nights characterized by a radiative cooling (wind £ 2m.s-2, clear sky) during spring 2001. The possible incidence of t…
Modélisation de la mobilité : la génération de trafic à l'échelle régionale
2006
Public transport management is currently going through important changes, passing from one scale to another: decentralizing from the national level and extending at the local level. The range of transport management powers of the French administrative regions have widened, thus creating new management problems. Within the context of these new questions, our research proposes management solutions which take into account both the continual evolution of daily mobility and the new scales of transport management. More specifically, we considered a specific stage often neglected in geographical approaches to the suject. This stage called traffic generation consists in modelling the process of cho…
