Flow clustering is one of the most important data mining methods for the analysis of.origin-destination (OD) ow data, and it may reveal the underlying mechanisms responsible for the spatial.distributions and temporal dynamics of geographical phenomena. Existing ow clustering approaches are.based mainly on the extension of traditional clustering methods to points by redening basic concepts or.some spatial association indictors of ows and the implementation of classic clustering processes, such as.aggregating, collecting or searching. However, current techniques still suffer from two main problems: poor.identication accuracy and complicated parameter selection processes. To resolve these problems, a new.clustering method is proposed in this study for arbitrarily shaped ow clusters based on the density domain.decomposition of ows. Simulation experiments based on our method and existing methods show that our.method outperforms the three most commonly used methods in terms of the overall identication rate and.almost all F1 measures, and it does not require any manual adjustments during the parameter selection.process. Finally, a case study is conducted on taxi trip data from Beijing. Several ow clusters are identied.to represent different types of residents' travel behaviors, including daily commuting, return travel, tourism.and behaviors on special days.
