Traffic Monitoring System for Smart City Based on Traffic Density Estimation

Abstract

Nowadays, traffic monitoring systems are at the frontline of smart city movement, and traffic density estimation is useful to a traffic monitoring system. The system of this work estimates traffic density using a five-layered CNN with a variety of input feature maps and filter sizes. There are 64, 64, 96, 96, and 96 feature maps for each pair of convolutions and max-pooling layers, and each pair's corresponding filter sizes are 5*5, 3*3, 5*5, 3*3, and 3*3. The proposed system divides the traffic into three categories: High, Medium, and Low traffic based on images that are taken from traffic videos that are recorded by traffic surveillance cameras. To test the system, we used the WSDT (Washington State Department of Traffic Transportation) Dataset of recorded video footage from the highway CCTVs in cities Seattle and Washington. The model is evaluated using parameters such as 0.99 precision, 0.99 recall, 0.99 f1-score, and model accuracy of 99.6 %. By examining the dataset, we have trained the model in such a manner to produce better results.

Brain Tumor Detection Using Advanced Deep Learning Implementations

“…The study was divided into two sections-the data was derived from images without and with diversifications in the respective order. After training the model, the results are analyzed in two main metrics-Loss and Prediction accuracy [22,23] for both sections, which are mentioned below in Table 5. Table 6 is a comparison of accuracies recorded by existing methods with diversified and non-diversified data models.…”

Web-Based Application for Plant Leaf Disease Detection

“…CNN are the deep learning model used for challenging pattern recognition and classification problems with many datasets. The four primary layers of the model are convolution, max-pooling, fully-connected, and output layers [19]. These layers are stacked on top of one another.…”
