Gestión de la vialidad invernal en la red de carreteras de la Generalitat de Cataluña

摘要

Roads in Catalonia form an integrated network of 12.110 km length witch is owned andmanaged by different public administrations. The Government of Catalonia is responsiblefor the maintenance of over 6.000 km length network. These roads pass through areaswith complex relief and large climatic diversity witch means that at least once a year, theentire network is liable to have frost or snow episodes. Furthermore, 400 km of roads areabove 1,000 meters high, where the winter road maintenance is very intense for at least 5months per year.Most of winter maintenance operations are under direct management, coordinating 37road operation centres, more than 125 snowplough and 99 bulk salt storage facilities witha total capacity of 11.000 tones.Catalonia’s Road Authority manages the Winter Maintenance Program witch is developedthrough:1. Annual preventive maintenance plan that includes preventive treatments2. Winter maintenance action plan that includes curative actions and snow removal3. Snow Emergency Plans (NEUCAT plan) and Avalanche Safety Plan (AllauCat)Since 2001 the Road Authority has developed a GPS-based system which helps tocoordinate and analyses all data collected by sensors and controls on snow-fightingvehicles. Through this system the Authority can know the position and the operationalsituation of each vehicle and generate report and maps that help in coordinate actionplans, conduct situations analyzes and reducing road maintenance costs in winters.
