This dataset provides JSON samples of intersection topology, including lanes, nodes, connections, and direction annotations, with typical issues such as broken lane links, invalid connections, coordinate offsets, duplicate nodes, and conflicting direction labels. Each sample includes an error analysis, a repaired structured topology, and a consistency report, supporting model training to localize spatial and topological errors and generate constraint-consistent repairs. It is suited to HD map quality assurance, intersection topology repair, and structured output model evaluation.
