The invention provides a whole road network traffic state prediction method and device, and relates to the technical field of intelligent traffic, and the method comprises the steps: obtaining the traffic flow data of a detection road section and a historical travel OD matrix of a whole road network; determining predicted traffic flow data of the detection road section in a preset time interval according to the traffic flow data, and determining a traffic flow deduction operation state of the whole road network in the preset time interval according to the historical travel OD matrix; determining an optimization model according to the predicted traffic flow data and the deduced traffic flow operation state; and determining a prediction OD according to the optimization model and a preset constraint condition, and performing state prediction of the whole road network. According to the invention, the problem that only a single type of traffic flow parameters can be predicted in the prior art is overcome, and the traffic state prediction problem of a road section without detection data in the road network is solved. In addition, mutual verification of prediction results of various traffic states such as OD, speed and flow can be realized, prediction deviation of a single type of data is reduced, and prediction accuracy of the traffic states is improved.

    本发明提供了一种全路网交通状态预测方法及装置,涉及智能交通技术领域,包括:获取检测路段的交通流数据和全路网的历史出行OD矩阵;根据交通流数据确定预设时间间隔内检测路段的预测交通流数据,并根据历史出行OD矩阵确定预设时间间隔内全路网的交通流推演运行状态;根据预测交通流数据和推演交通流运行状态确定优化模型;根据优化模型和预设约束条件确定预测OD,进行全路网的状态预测。本发明克服了现有技术中只能对单一种类的交通流参数进行预测的问题,且解决了路网中无检测数据的路段的交通状态预测问题。本发明还可实现OD、速度、流量等多种交通状态预测结果的相互校验,减小单一种类数据的预测偏差,提高交通状态的预测准确度。
