Abstract
Driving interaction, a critical yet underrepresented element in trajectory datasets, is central to the development and evaluation of autonomous driving systems. This work presents InterHub, a curated dataset of dense multi-agent interaction events, derived from large-scale naturalistic driving recordings. We employ formal methods to describe and extract multi-agent interaction events, exposing the limitations of existing autonomous driving solutions. The dataset is accompanied by an open-source toolkit that enables users to expand InterHub by mining additional interaction events from both public and private driving data. By offering a unified taxonomy, rich annotations, and extensible tools, InterHub supports diverse research needs-from interaction behavior modeling to algorithm benchmarking-and promotes reproducibility, scalability, and cross-dataset comparison in autonomous driving studies.
