New SAGE framework enhances autonomous vehicle path prediction in work zones

Researchers have developed SAGE (Semantic-to-Action Grounded Execution), a novel framework designed to improve pathway prediction for automated vehicles in work zones. SAGE integrates a vision-language model (VLM) with geometric predictors to select the most appropriate path, adhering to traffic control guidelines. The system analyzes visible traffic control devices and uses the VLM's trajectory as a preference over geometrically generated paths. Tested on real-world roadwork scenarios, SAGE demonstrated a reduction in displacement errors and hard-constraint violations compared to existing methods. AI

IMPACT This framework could improve the safety and efficiency of autonomous vehicles operating in complex, dynamic roadwork environments.
