Published: 14 November 2025 | Total Citations: 0 | Total Downloads: 0
Keywords: Object Detection, LLM, Navigation Assistance
This research outlines a novel navigation assistance framework that integrates real-time object detection with Large Language Models (LLMs) to generate context-aware driving instructions. By converting raw visual detections into a structured intermediate representation, the system enhances controllability and reduces irrelevant generation. The framework demonstrates superior detection performance and introduces the 'Feasibility Score' for human evaluation, positioning it as a significant step towards human-centered AI for road safety.
Executive Impact & Business Value
The integration of advanced object detection and LLMs offers a transformative approach to navigation, moving beyond simple alerts to provide nuanced, context-aware instructions. This significantly reduces driver cognitive load and improves situational awareness, directly addressing the rising global challenge of traffic accidents caused by human error. For businesses, this translates to opportunities in smarter vehicle technology, insurance risk reduction, and AI-powered urban planning.

System Architecture
The proposed framework is an end-to-end pipeline transforming raw visual input into actionable natural language guidance. It's modular, ensuring robust real-time processing. The visual perception module uses high-performance object detection (e.g., RT-DETR) to identify traffic elements. Its output, a serialized descriptive string, decouples perception from reasoning. The LLM then interprets this structured text to generate context-aware instructions, guiding the driver effectively.

Key Findings
Our findings highlight a crucial trade-off: RT-DETR-x achieves state-of-the-art accuracy (mAP50-95 of 0.812) but with higher latency (36.17 ms/image), ideal for safety-critical systems. In contrast, YOLOv11-n offers superior speed (12.01 ms/image) with competitive accuracy (mAP50-95 of 0.767), suitable for resource-constrained embedded systems. The LLM evaluation revealed that larger, general models like Llama-3.2-11B-Vision-Instruct excel in fluency and completeness, while smaller, regionally-tuned models (e.g., Bahasa-4b-chat) show superior relevance and coherence due to local linguistic adaptation. The modular architecture validates independent optimization of perception and language components.
| Component | Accuracy | Speed | Key Benefit |
|---|---|---|---|
| RT-DETR-x (Perception) | Highest (0.812 mAP) | Slower (36.17ms) | Maximum reliability for safety-critical systems |
| YOLOv11-n (Perception) | Competitive (0.767 mAP) | Fastest (12.01ms) | Efficiency for resource-constrained embedded systems |
| Llama-3.2-11B (Language) | High fluency & completeness | General purpose | Robust, detailed, grammatically correct instructions |
| Regional LLMs (Language) | High relevance & coherence | Locally adapted | Intuitive, contextually appropriate for specific users/regions |
Deployment Roadmap
Transitioning this framework from research to a deployable in-vehicle application involves several key development areas. Optimizing computational efficiency for dashboard camera platforms is critical. Human-Machine Interface (HMI) integration, leveraging Text-to-Speech and Head-Up Display, will maximize driver acceptance. Finally, extensive field trials in real-world driving environments are necessary to validate robustness against imperfect detections and identify optimal detector-LLM pairings.
