Abstract: To reduce the risk of traffic accidents and enhance the safety and efficiency of autonomous vehicles, a method for traffic risk prediction in autonomous driving based on the Adaptive Neuro-Fuzzy Inference System (ANFIS) has been studied. Firstly, vehicle speed and acceleration are used as quantitative indicators to construct the input parameters of the traffic risk prediction model. Secondly, the data is fuzzified using the MATLAB toolbox. The membership degrees of the inputs are determined through fuzzy rules, and the credibility of the membership degrees and the comprehensive adaptability of the rules are calculated. Combining this with the training capability of artificial neural networks, the decision quality and risk management capability of the model are optimized. Finally, the model is verified through simulation, and the results show that the traffic risk prediction error of the model is approximately 13.77%, which is relatively low. This demonstrates the model’s effectiveness in predicting traffic risks for autonomous vehicles and provides strong support for further optimizing the performance of autonomous vehicles and ensuring their driving safety and reliability.
