Traffic Sign Detection & Recognition — YOLOv8

A YOLOv8 object detection model fine-tuned via transfer learning for real-time traffic sign detection and classification. Trained as part of a BS Software Engineering thesis project and subsequently deployed as a public web application.

Usage

python

from ultralytics import YOLO
import torch

# Allow loading of custom YOLOv8 checkpoint
_orig = torch.load
def _safe_load(*args, **kwargs):
    kwargs["weights_only"] = False
    return _orig(*args, **kwargs)
torch.load = _safe_load

# Load model
model = YOLO("best_roboflow.pt")

# Run inference
results = model.predict("your_image.jpg", conf=0.4)
results[0].show()

Use Cases

Driver-assistance systems (ADAS): real-time alerting for speed limits, stop signs, and warning signs
Dashcam footage auditing: automatically flagging missed or obscured signage for road-safety compliance reviews
Autonomous vehicle perception: as a building-block detection module feeding into higher-level driving decision systems

Training Details

Dataset sourced and annotated via Roboflow
Fine-tuned from YOLOv8 pretrained weights via transfer learning
21 traffic sign classes covering common urban road signage

Deployment

This model is deployed as a Streamlit web application on Hugging Face Spaces. See the traffic-sign-detector Space for the full application code and deployment details.
