# Qwen2.5-VL-3B-Instruct-Traffic

**Qwen2.5-VL-3B-Instruct-Traffic** is a multimodal model fine-tuned on the **MITS (Multimodal Intelligent Traffic Surveillance)** dataset for intelligent traffic surveillance scenarios.

- **Tasks:** recognition, counting, localization, background awareness, reasoning
- **Data:** 170,400 images + ~5M instruction-following VQA pairs from MITS
- **Modality:** Image + Text → Text
- **Domain:** traffic scenes (congestion, accidents, construction, smoke/fireworks, unusual weather, spills, etc.)

- 💻 Usage & examples: please refer to the GitHub repo  
  **https://github.com/LifeIsSoSolong/Multimodal-Intelligent-Traffic-Surveillance-Dataset-Models**

## Intended Use
- Urban traffic monitoring, incident analysis, visual question answering for transportation management
- Research on ITS-specific multimodal reasoning and instruction following

## Model Inputs/Outputs
- **Input:** an image (traffic scene) + a natural language instruction/question
- **Output:** a natural language response (e.g., description, count, event reasoning)

## Training Summary
- Objective: instruction tuning on MITS traffic QA
- Backbone family: Qwen2.5-VL 3B Instruct
- Notes: align vision-language features to traffic-centric concepts and events

## Limitations & Notes
- The model may make mistakes on rare objects or extreme weather/night scenes not well represented in training.
- Not a safety-critical system; human verification is required for real-world decisions.

## License
- Follow the licenses of this model and the MITS dataset as stated on their ModelScope pages.
