This dataset provides question-answer examples built around highway HD map lane segments and their predecessor, successor, and connection relationships. Samples cover reachability checks for specified lanes or road exits and inference of connecting paths, with topology data, questions, step-by-step reasoning, reachability results, paths, and concise answers. It supports reasoning supervised fine-tuning, map connectivity question answering, and evaluation of models for autonomous driving maps.
