| # **Traffic-Density-Classification** |
| > **Traffic-Density-Classification** is an image classification vision-language encoder model fine-tuned from **google/siglip2-base-patch16-224** for a single-label classification task. It is designed to classify images into **traffic density** categories using the **SiglipForImageClassification** architecture. |
|

| ```py |
| Classification Report: |
| precision recall f1-score support |
| |
| high-traffic 0.8647 0.8410 0.8527 585 |
| low-traffic 0.8778 0.9485 0.9118 3803 |
| medium-traffic 0.7785 0.6453 0.7057 1187 |
| no-traffic 0.8730 0.7292 0.7946 528 |

| macro avg 0.8485 0.7910 0.8162 6103 |
| weighted avg 0.8568 0.8602 0.8559 6103 |
| ``` |
|
|
|  |
|
|
| The model categorizes images into the following 4 classes: |
| - **Class 0:** "high-traffic" |
| - **Class 1:** "low-traffic" |
| - **Class 2:** "medium-traffic" |
| - **Class 3:** "no-traffic" |

|
| # **Intended Use:** |
|
|
| The **Traffic-Density-Classification** model is designed for traffic image classification. It helps categorize traffic density levels into predefined categories. Potential use cases include: |
|
|
| - **Traffic Monitoring:** Classifying images from traffic cameras to assess congestion levels. |
| - **Smart City Applications:** Assisting in traffic flow management and congestion reduction strategies. |
| - **Automated Traffic Analysis:** Helping transportation authorities analyze and optimize road usage. |
| - **AI Research:** Supporting computer vision-based traffic density classification models. |
