The embodiment of the invention discloses a driving behavior and traffic risk early warning method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring original survey data of a highway site to obtain initial data; performing wavelet filtering analysis on the initial data to obtain an analysis result; normalization processing of traffic network data is carried out on an analysis result; inputting the normalization processing result into a prediction model for traffic flow prediction and driving behavior analysis to obtain an output result; carrying out reverse normalization processing; carrying out risk early warning according to a reverse normalization processing result; wherein the prediction model is obtained by training the multi-hidden-layer BP neural network by using the traffic flow of the expressway as a sample set. By implementing the method provided by the embodiment of the invention, the problems in the prior art can be solved, the accuracy, stability and reliability of a traffic volume acquisition and prediction system are improved, and the traffic flow change and complexity can be better dealt with.

    本发明实施例公开了一种驾驶行为及通行风险预警方法、装置、计算机设备及存储介质。方法包括:获取公路站点原始调查数据,以得到初始数据;对初始数据进行小波滤波分析,以得到分析结果;对分析结果进行交通路网数据的归一化处理;将归一化处理结果输入至预测模型中进行交通流量的预测以及驾驶行为的分析,以得到输出结果;进行反归一化处理;根据反归一化处理结果进行风险预警;其中,预测模型是通过采用高速公路的交通流量作为样本集训练多隐含层BP神经网络所得的。通过实施本发明实施例的方法可以解决现有技术所存在的问题,实现提高交通量采集和预测系统的准确性、稳定性和可靠性,有助于更好地应对交通流量变化和复杂性。
