qwen3-14b-instruct-traffic-explainer

This model is designed to explain cooperative traffic control decisions in natural language.

It takes a structured prompt that describes:

• the current traffic state
• the signal phase
• platoon-related observations
• the actions taken by the traffic control system

It then generates a short explanation of why those actions were taken, with emphasis on how signal control, platoon formation, and speed control work together.

This model is intended for:

• traffic decision interpretation
• intelligent transportation system demos
• human-readable explanation generation for cooperative control outputs

Input

The model works best when the input follows a structured prompt format that includes:

• traffic state
• action semantics
• actions taken
• explanation task description

Output

The model generates an explanation in natural language, typically using the format:

<explanation>...</explanation>
