Researchers have developed StateBridge, a novel framework for traffic video captioning and visual question answering (VQA) that excels in synthetic-to-real generalization. The approach leverages phase-aware clip construction, summaries of pedestrian and vehicle tracks, and structured prompts to ground vision-language models in stable traffic evidence. By fine-tuning public models on synthetic data and employing fact-locked caption fusion and evidence-diverse VQA consensus, StateBridge achieved a high score on the AI City Challenge 2026 Track 2, demonstrating the efficacy of structured evidence transfer for traffic safety applications.
