Utilização de imagens associadas ao georreferenciamento para monitoramento do estado de conservação de ferrovias

Abstract

In Brazil, the share of the rail way in the freight transport matrix corresponds to only 20.7%. However, this mode is suitable for long distance transport, which is the case in Brazil. In order for the railroads to operate in good conditions, maintenance actions are necessary. This paper proposes the use of images and the georeferencing of defects found through them to evaluate the state of conservation of railways. In the 23km of line analyzed the following items were characterized: the state of conservation of pontoons, defects on the ballast layer, the presence of vegetation and garbage, invasion to railroad lands (the domain range) and the occurrence of clandestine grade crossings. The use of images proved to be an efficient tool. Predominance of defects was observed in a certain part of the stretch, which coincides with the higher incidence of human activity along the road margins.
