Utilização de imagens obtidas por meio de satélites em auditorias de obras rodoviárias

Abstract

In Brazil, road transport is responsible for 65% of cargo transport, however, when comparing the area of the Brazilian territory with the mileage of the highways, the country has a low density in its road network. As a consequence of this, the proper maintenance of these routes is necessary, which end up generating large movements of public money, for this reason, it is necessary to carry out the audit processes. The objective of this work is to demonstrate in a descriptive and exploratory way the advantages and limitations in the use of satellite images in audits of road works. For this, a news survey was carried out and a sample of 152 cases from the Federal Court of Auditors (TCU) was selected, which after a refined analysis of the data, only 4 presented the use of these images. A road safety audit simulation was also carried out, demonstrating the main limitations of the use of spatial images and establishing parameters for the analysis of audit costs. Thus, the use of satellite images appears as an alternative to reduce time and cost for carrying out audits, requiring new studies to develop the method.
