This paper introduces City-Networks, a large-scale transfer learning dataset derived from real-world urban road networks, for research on long-distance dependency learning. This dataset contains graphs with over 100,000 nodes, with a much larger diameter than existing benchmarks, allowing for natural inclusion of long-distance interactions. Furthermore, we annotate the graph based on node centrality, ensuring that classification tasks require information about distant nodes. Finally, we propose a model-independent metric for quantifying long-distance dependencies.
