Hypothesis
Can an automatic brake system effectively detect traffic lights and apply brakes based on their states?
Conclusion
The proposed system achieved a 96% accuracy in detecting traffic light states and a 1 meter average error in distance estimation during real-world tests.
Supporting Evidence
- The traffic light detection model achieved a mean Average Precision (mAP) of 0.96 for distances less than 13 m.
- The system's response time was measured at 0.23 seconds.
- An average Root Mean Squared Error (RMSE) of 1 m was found for distance estimation during on-road experiments.
Takeaway
This study created a smart braking system for cars that can see traffic lights and stop the car when needed, making driving safer.
Methodology
The study used a Jetson TX2 and a ZED camera to detect traffic lights and apply brakes based on their states using fuzzy logic.
Limitations
The system struggled to accurately estimate distances to traffic lights beyond 13 meters due to environmental factors.
