The invention provides a traffic accident prediction method and device, a terminal and a storage medium. The method comprises the following steps: determining a possible moment when a vehicle has a traffic accident; acquiring first vehicle data within a first preset duration before the possible moment and second vehicle data within a second preset duration after the possible moment; based on the first vehicle data, extracting first feature data for traffic accident prediction; based on the second vehicle data, extracting second feature data for traffic accident prediction; inputting the first feature data and the second feature data into a pre-trained traffic accident prediction model to obtain a traffic accident occurrence probability; and if the traffic accident occurrence probability is greater than a preset probability threshold, predicting that a traffic accident occurs at a possible moment. According to the method, whether the traffic accident occurs at the possible moment can be accurately predicted based on the vehicle data in a period of time before and after the possible moment of the traffic accident, and the method can be suitable for commercial vehicles and other medium-sized or large-sized vehicles.
本发明提供一种交通事故预测方法、装置、终端及存储介质。该方法包括:确定车辆发生交通事故的可能时刻;获取可能时刻前第一预设时长内的第一车辆数据和可能时刻后第二预设时长内的第二车辆数据;基于第一车辆数据,提取用于进行交通事故预测的第一特征数据;基于第二车辆数据,提取用于进行交通事故预测的第二特征数据;将第一特征数据和第二特征数据输入预先训练好的交通事故预测模型中,得到交通事故发生概率;若交通事故发生概率大于预设概率阈值,则预测在可能时刻发生交通事故。本发明可基于发生交通事故的可能时刻的前后各一段时间内的车辆数据,准确预测在该可能时刻是否发生交通事故,可以适用于商用车等中型或大型车辆。
