This work has as its main objectives to develop and evaluate a successive averages algorithm applied to the reconstruction of the synthetic OD matrix based on traffic flow counts. Initially, it is discussed conceptually the bi-level solution strategy for this fixed-point op-timization problem and described the application of the method of successive averages as a hierarchical solution technique, detailing the proposed algorithm for computer implementation. Following, it is presented an experiment to verify the performance of this algorithm, comparing its results to those obtained with TransCAD software. The conclusions indicate that the assessed method was able to produce good results, even better than TransCAD’s. However, in none of the analyzed cases it was possible to reconstruct the originalmatrix with a high level of precision. At the end, some research questions are highlighted which may improve modeling efforts of the synthetic OD matrix in congested transportation networks.
