Traffic Sign Recognition System using CNN

This paper shows the development and working of a traffic sign recognition system using Convolutional Neural Networks (CNNs) for the accurate detection and classification of traffic signs from images (captured by a camera mounted on a vehicle). The system achieved a high classification accuracy of 95% on a validation set and consists of three main components: image pre-processing, CNN model, and post-processing. The pre-processing step involves resizing, normalization, and augmentation, while the CNN model uses multiple convolutional and fully connected layers to classify input  images into different traffic sign categories. Post- processing involves non-maximum suppression and  thresholding to remove duplicate detections and filter out false positives. Testing on a real-world dataset resulted in an overall accuracy of 94.5%, demonstrating the system's robustness to varying lighting and weather conditions, as well as its ability to accurately recognize traffic signs at different distances and angles. This proposed system using CNNs is a promising solution for improving road safety and reducing accidents caused by driver error.
