RoadSceneVQA-G

Answer with Evidence: Consistency-Aware Grounded Visual Question Answering for Roadside Traffic Scenes

A benchmark of 34.7K question-answer pairs for roadside traffic scenes where every free-form answer is linked to witnessing bounding boxes to measure answer-grounding consistency.

About

RoadSceneVQA-G contains 34.7K open-ended questions on roadside traffic imagery, with each answer paired with zero or more ground-truth bounding boxes that witness the claim. It addresses say-point mismatch by requiring explicit alignment between textual assertions and visual evidence.

The benchmark uses the Answer-Grounding Consistency (AGC) evaluation suite to penalize contradictions between answers and localized boxes. Experiments show that existing models suffer from low consistency, which the proposed EtA method significantly improves.
