abstract: Clustering of smart card data captured by automated fare collection (AFC) systems has traditionally
been viewed as an unsupervised method. However,some additional information about human behaviour
is available in addition to the smart card data points that can facilitate better partitioning of the data. In
this paper, such prior knowledge is translated into pairwise constraints and used with the COPKMEANS clustering algorithm to identify user activities. The effectiveness of the method was
evaluated using performance evaluation measures by comparison of the results with the ground truth.
The results demonstrate that pairwise constraints significantly enhance the accuracy of the clusters.
