Researchers have introduced the Land Transportation Dataset (LTD), a new large-scale, open-source vision-language dataset designed for open-ended reasoning in urban traffic environments. The dataset comprises 11.6K VQA pairs from diverse roadside camera perspectives, supporting tasks like object grounding, camera selection, and risk analysis. To address the limitations of current models in city-scale traffic analysis, they also developed UniVLT, a transportation foundation model trained on LTD that unifies microscopic and macroscopic reasoning capabilities.
