The invention discloses a highway network traffic state deduction method and device and a storage medium, and the method comprises the steps: carrying out the cellular division according to the positions of a highway portal, a toll station and an interchange node; relation fitting is carried out on the traffic flow elements of the expressway cells through an AI-agent model; and after the relational expression fitting is completed, inputting the traffic volume entering the first cell at a certain moment and the traffic volume entering the main line cell by each toll station or interchange node into the relational expression obtained by fitting so as to deduce the traffic state of the expressway network at the moment. According to the method, parameter calibration of the model is replaced by data driving, the accuracy of expressway network traffic state deduction can be further improved, and expressway managers are helped to make scientific and reasonable decisions. The method can be widely applied to the field of artificial intelligence-intelligent traffic.
本发明公开了一种高速公路网交通状态推演方法、装置及存储介质,其中方法包括:根据高速公路门架、收费站和互通立交节点的位置,进行元胞划分;通过AI‑agent模型对高速公路元胞各交通流要素间进行关系式拟合;在关系式拟合完成后,将某一时刻进入首元胞的交通量以及各个收费站或互通立交节点进入主线元胞的交通量输入拟合得到的关系式,以推演该时刻高速公路网的交通状态。本发明采用数据驱动代替了模型的参数标定,能够进一步提高高速公路网交通状态推演的准确性,帮助高速公路管理者做出科学合理的决策。本发明可广泛应用于人工智能‑智能交通领域。
