The invention relates to the technical field of traffic safety, in particular to a highway traffic safety intelligent early warning system and method based on artificial intelligence. The system is composed of a data acquisition module, a data preprocessing module, an intelligent analysis module, an early warning decision module and an interactive early warning interface, and the data acquisition module collects multi-parameter data through three ways of a sensor, a monitoring system and a meteorological station; the data preprocessing module cleans, standardizes, normalizes and supplements missing values for the collected multi-parameter data, trains the extracted features through the intelligent analysis module by using a feedforward neural network FFNN + self-attention mechanism, constructs a multi-dimensional risk prediction model, automatically identifies the change of a traffic mode, predicts potential dangerous events, and improves the risk prediction efficiency. The interactive response interface displays the early warning information and the multi-parameter data collected in real time. According to the invention, road conditions and traffic risk conditions can be more comprehensively known, powerful data support is provided for decision making of an early warning system, and the early warning accuracy and intelligent level are significantly improved.

    本发明涉及交通安全技术领域,具体是涉及一种基于人工智能的公路交通安全智能预警系统及方法。由数据采集模块、数据预处理模块、智能分析模块、预警决策模块以及交互式预警界面组成,所述数据采集模块通过传感器、监控系统、气象站三种途径收集多参数数据,所述数据预处理模块对收集到的多参数数据进行清洗、标准化、归一化和缺失值补充,通过智能分析模块运用前馈神经网络FFNN+自注意力机制对提取的特征进行训练,构建多维度风险预测模型,自动识别交通模式的变化,预测潜在危险事件,交互式响应界面展示预警信息与实时采集的多参数数据。本发明能够能够更全面地了解路况和交通风险情况,为预警系统的决策提供有力的数据支持,显著提高预警的准确性和智能化水平。
