The invention relates to the technical field of real-time traffic, in particular to a traffic jam prediction system which comprises a road monitoring unit and a central processing unit, the output end of the road monitoring unit is connected with the input end of a wireless communication module, and the output end of the wireless communication module is connected with the input end of a data prediction unit. The data prediction unit comprises a monitoring ball machine module. According to the traffic jam prediction system, state vector search is performed according to workday information, holiday information and weather information which can be predicted in advance, the most similar R historical state vectors are searched out, a prediction value is calculated according to the corresponding R traffic jam indexes, and according to the periodical characteristics of traffic speed data, the prediction value is calculated according to the R traffic jam indexes. Traffic speed data and traffic speed data at adjacent moments, adjacent days or before several weeks have certain similarity, and the accuracy of traffic jam prediction can be improved through a construction proximity, periodicity and tendency matrix combination deep learning method of the GRU-FC network model.
本发明涉及实时交通技术领域,具体为一种交通拥堵预测系统,包括道路监测单元和中央处理器,所述道路监测单元的输出端和无线通信模块的输入端连接,所述无线通信模块的输出端和数据预测单元的输入端连接,所述数据预测单元包括监控球机模块。该交通拥堵预测系统,根据可提前预知的工作日信息、放假信息、气象信息进行状态向量搜索,搜索出最相似的R个历史状态向量,再根据所对应的R个交通拥堵指数计算预测值,以及根据交通速度数据的周期性特征可知,交通速度数据与相邻时刻,相邻天或数周前的交通速度数据具有一定的相似性,通过GRU‑FC网络模型具备的构建邻近性,周期性和趋势性矩阵结合深度学习方法,可以提高交通拥堵预测的准确性。
