%description
OD-means is a hierarchical adaptive k-means algorithm based on
origin-destination pairs. In the first layer of the hierarchy, the
clusters are separated automatically based on the variation of the
within-cluster distance of each cluster until convergence. The second
layer of the hierarchy corresponds to the sub clustering process of small
clusters based on the distance between the origin and destination of each
cluster.
