Hybrid CNN-LSTM model for enhanced accident detection using temporal feature learning
摘要
Accurate and timely accident detection is crucial for enhancing road safety and emergency response systems. In this study, we propose a CNN+LSTM-based deep learning model for accident detection using sequential image data, aiming to leverage spatial and temporal features for higher predictive accuracy. We evaluated the efficiency of the proposed CNN+LSTM model by comparing its performance with that of CNN+GRU and Simple CNN.According to the experimental data, the CNN+LSTM model performs better in terms of accuracy and loss than both CNN+GRU and Simple CNN. The proposed CNN+LSTM model achieves a training accuracy of 90.22%, validation accuracy of 91.30%, and testing accuracy of 91.31%, with a corresponding training loss of 0.2113, validation loss of 0.2306, and testing loss of 0.1840. In comparison, the CNN+GRU model attains a training accuracy of 87.55%, validation accuracy of 86.96%, and testing accuracy of 87.62%, with a training loss of 0.2865, validation loss of 0.3371, and testing loss of 0.2597. The Simple CNN model records a training accuracy of 89.30%, validation accuracy of 90.82%, and testing accuracy of 90.90%, with a training loss of 0.2769, validation loss of 0.2592, and testing loss of 0.2561.
