Deep Learning Method to Detect the Road Cracks and Potholes for燬mart燙ities

Abstract

The increasing global population at a rapid pace makes road traffic dense; managing such massive traffic is challenging. In developing countries like Pakistan, road traffic accidents (RTA) have the highest mortality percentage among other Asian countries. The main reasons for RTAs are road cracks and potholes. Understanding the need for an automated system for the detection of cracks and potholes, this study proposes a decision support system (DSS) for an autonomous road information system for smart city development with the use of deep learning. The proposed DSS works in layers where initially the image of roads is captured and coordinates attached to the image with the help of global positioning system (GPS), communicated to the decision layer to find about the cracks and potholes in the roads, and eventually, that information is passed to the road management information system, which gives information to drivers and the maintenance department. For the decision layer, we projected a CNN-based model for pothole crack detection (PCD). Aimed at training, a K-fold cross-validation strategy was used where the value of K was set to 10. The training of PCD was completed with a self-collected dataset consisting of 6000 images from Pakistani roads. The proposed PCD achieved 98% of precision, 97% recall, and accuracy while testing on unseen images. The results produced by our model are higher than the existing model in terms of performance and computational cost, which proves its significance.

“…Not only is deep learning excellent at recognizing facial expressions, 52 but it has also shown promise in other areas, such as smart city planning, 53 skin cancer diagnosis, 54 At the same time, the base model will remain frozen. The obtained in-depth features concatenate them.…”

“…When we talk about making a network “deep,” we mean it has several layers. Not only is deep learning excellent at recognizing facial expressions, 52 but it has also shown promise in other areas, such as smart city planning, 53 skin cancer diagnosis, 54 and so forth. Convolutional neural networks are the method of choice when dealing with image‐based issues.…”

Utilising Convolutional Neural Networks for Pavement Distress Classification and Detection

“…Zhang et al [14] trained a CNN model for crack patch classification, outperforming support vector machines and tree-based models. Chu et al [15] proposed a pothole crack detection (PCD) model based on CNNs optimized with K-fold cross-validation, achieving high precision and recall rates in identifying potholes. Pintelas et al [16] introduced Multiview convolutional neural networks, which enhanced the performance of pre-trained neural networks like ResNet and VGG.…”
