RoadBench: Benchmarking MLLMs on Fine-Grained Spatial Understanding and Reasoning under Urban Road Scenarios

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • A new benchmark called RoadBench has been introduced to evaluate the fine-grained spatial understanding and reasoning capabilities of multimodal large language models (MLLMs) in urban road scenarios, focusing on road markings as a critical element. This benchmark includes six tasks with 9,121 manually verified test cases, utilizing BEV and FPV image inputs to assess MLLMs' performance.
  • The development of RoadBench is significant as it addresses a notable gap in the evaluation of MLLMs, particularly in complex urban environments where spatial reasoning is essential for applications such as autonomous driving and urban planning.
  • This initiative reflects a growing trend in AI research to enhance the capabilities of MLLMs by integrating various modalities and addressing specific challenges, such as spatial reasoning and deception detection in social interactions, which are critical for advancing AI applications in real-world scenarios.
