The invention provides an early warning method and system based on a holiday and festival congestion prediction algorithm, and the method comprises the steps: firstly obtaining a traffic data set, carrying out the preprocessing, carrying out the fusion of a time feature, a historical feature, a spatial position variable, and weather data with the preprocessed traffic data set, and forming a complete traffic data set, then selecting a preset data granularity and adopting a holiday congestion prediction algorithm to establish an ST-GCN model for training to obtain an optimal ST-GCN model to predict a traffic congestion road condition, establishing an evaluation index according to the actual traffic data and the predicted traffic congestion road condition, adopting a comparison model to evaluate the ST-GCN model, verifying the ST-GCN model as the optimal model, and obtaining the optimal ST-GCN model. According to the method and the system, the traffic congestion condition is predicted, the specific congestion evaluation index is adopted to evaluate the predicted traffic congestion condition, the traffic congestion condition is evaluated, and finally the traffic congestion condition is displayed and early warned through the information board arranged on the expressway, so that the passing efficiency of the expressway is effectively improved, and the traffic flow trend during holidays and festivals is efficiently and accurately predicted.
本发明提供了一种基于节假日拥堵预测算法的预警方法及系统,该方法先获取交通数据集并进行预处理,将时间特征、历史特征、空间位置变量以及天气数据与预处理后的交通数据集进行融合,形成完整交通数据集,再选择预设的数据粒度并采用节假日拥堵预测算法建立ST‑GCN模型进行训练,得到最优ST‑GCN模型以预测交通拥堵路况,根据实际交通数据和预测的交通拥堵路况建立评估指标,采用对比模型对ST‑GCN模型进行评估,验证其为最优模型,并采用特定的拥堵评价指标对所预测的交通拥堵路况进行评估,评估出交通拥堵情况,最后通过高速公路上布设的情报板将交通拥堵情况进行展示并预警,有效提高了高速公路的通行效率,高效准确预测节假日期间的交通流量趋势。
