The present study uses Data Envelopment Analysis (DEA) to evaluate the temporal efficiency of Brazilian federal highways
that take part on the Highways Grant Program. The study is based on the annual reports published by Brazilian National Land
Transport from 2005 to 2008. We apply two DEA models: the first one aims to evaluate the concessionaire of the highway
efficiency regarding the use of capital goods and human resources while the second one measures the efficiency regarding the
use of incomes and investments for the highway security. We also propose a efficiency global index which is the product of
efficiency indices of the two models applied.
