Classification of Road Traffic Congestion Levels from Vehicle's Moving Patterns: A Comparison Between Artificial Neural Network and Decision Tree Algorithm

摘要

We proposed a technique to identify road traffic congestion levels from velocity of mobile sensors with high accuracy and consistent with motorists' judgments. The data collection utilized a GPS device, a webcam, and an opinion survey. Human perceptions were used to rate the traffic congestion levels into three levels: light, heavy, and jam. We successfully extracted vehicle's moving patterns using a sliding windows technique. Then the moving patterns were fed into ANN and J48 algorithms. The comparison between two learning algorithms yielded that the J48 model shown the best result which achieved accuracy as high as 91.29%. By implementing the model on the existing traffic report systems, the reports will cover on comprehensive areas. The proposed method can be applied to any parts of the world.
