Nanni M., Trasarti R. K-BestMatch reconstruction and comparison of trajectory data. In: ICDMW'09 - International Workshop on Spatial and Spatiotemporal Data Mining (SSTDM-09) In Cooperation with IEEE ICDM 2009 (Miami, Florida, USA, 6 December 2009). Proceedings, pp. 610 - 615. IEEE, 2009.
In this paper we propose a map matching method to overcoming the limitations of standard best-match recon- struction strategies. We use a more flexible approach which consider the k-optimal alternative paths to reconstruct the trajectories from the GPS raw data. The preliminary results, obtained on a real dataset of car users in Milan area, suggest that our method leads to beneficial effects on the successive analysis to be performed such as KNN and clustering
