A GLOBAL SYSTEM OF ROAD WEATHER FORECAST TO THE BENEFIT OF WINTER SERVICEABILITY

摘要

The Direction Interdépartementale des Routes Sud-Ouest (DIR Sud-Ouest) of Francernprovides winter serviceability of 950 km of national roads spread over nine departments inrnzones of plain, piedmont and mountain. The traffic stakes are diverse and important.rnThe period of winter serviceability lasts four months in plain and six months in mountain.rnDuring this period, the DIR mobilizes its 21 centers of maintenance and interventionrn(Centres d’Entretien et d’Intervention : CEI) and its 2 engineering and traffic managementrncenters (Centres d’Ingénierie et de Gestion du Trafic : CIGT) in the context of a particularrnorganization.rnOne of the essential elements of the device set up by the DIR is the global system of roadrnweather forecast and the follow-up of the weather conditions supplied by METEOFRANCE.rnThis system supplies, on the scale of the network of the DIR, the analysis of the eventsrnimpacting roads in real time and in a projected way.rnIt allows managerial staff, from the closer to the ground (Manager Winter Serviceability inrnCEI) to the direction (executive staff available on call), and the traffic management centersrn(CIGT), to anticipate in order to organize and realize their missions at best.
