This dataset contains processed data used for the experiments presented in articles "Optimal Transport-Based Clustering of Attributed Graphs with an Application to Road Traffic Data", and "Integrating Structure and Attributes for TransportationNetwork Partitioning via Optimal Transport". The dataset includes raw city data provided by an external partner of urban transportation networks and associated attributes used for evaluating the proposed methodology. This repository provides data required to reproduce the experiments, together with metadata describing their origin and preprocessing steps. The code used to process and analyze these datasets is available at : GitHub repository for "Optimal Transport-Based Clustering of Attributed Graphs with an Application to Road Traffic Data" GitHub repository for "Integrating Structure and Attributes for TransportationNetwork Partitioning via Optimal Transport"
