Étude pilote sur la protection aérodynamique des véhicules an voisinage de P.S. on P.I. autoroutiers.

The aim of the study was the variance analyses of side winds which can disturb the equilibrium of a vehicle in the neighbourhood of engineering works and to study eventual modifications to such engineering works and if there was a possibility to provide them with wind shields. The study was undertaken on a motorway which crossed a highway under and over.
