According to statistics, there are approximately 1.24 million deaths due to traffic accidents worldwide every year, and road traffic safety is expected to become the fifth leading cause of death globally by 2030. Therefore, collision avoidance systems have been proposed to predict collision risks and prevent accidents. Existing vehicle collision risk prediction systems based on Long Short-Term Memory (LSTM) networks do not consider the optimization of model hyperparameters. In this paper, we integrate LSTM and Sparrow Search Algorithm (SSA) to optimize four hyperparameters of the LSTM model. This algorithm predicts collision risks by considering both vehicle and driver factors. The proposed model is evaluated using the Next Generation Simulation (NGSIM) dataset, and the experimental results indicate that the vehicle collision warning model based on SSA-LSTM has achieved an accuracy of 97.0%, which is a 2.1% improvement over the LSTM model. Moreover, the model has made significant improvements in reducing both false alarm rate and missed detection rate.
