The invention belongs to the technical field of intelligent traffic, and discloses an intelligent traffic digital twin processing method and system based on big data, and the method comprises the steps: obtaining the dynamic perception information of a vehicle and the specific position of the vehicle; extracting historical traffic data of a road section where the vehicle is located, obtaining basic geographic information data of the required road section, and performing position matching and data association; carrying out data fusion to obtain multi-source, heterogeneous and multi-tense fusion data; real-time simulation based on fusion data is realized in a virtual environment; and the digital twin data, the simulation calculation result and the decision information are fused and presented, and a signal control system is established to control traffic facilities in real space in real time. According to the invention, by adopting a digital twinning processing mode, the collected information is corresponding to the virtual environment, virtual-real combination is realized, the comprehensiveness and accuracy of traffic state prediction based on complex data are further improved, and the road traffic state prediction and the optimal control of congested road sections can be better carried out.

    本发明属于智能交通技术领域,公开了一种基于大数据的智能交通数字孪生处理方法及系统,包括:获取车辆的动态感知信息及所处的具体位置;提取车辆所处位置路段的历史交通数据,获取所需路段的基础地理信息数据,进行位置匹配和数据关联;进行数据融合,获得多源、异构、多时态的融合数据;在虚拟环境中实现基于融合数据的实时仿真;将数字孪生数据、仿真计算结果和决策信息融合呈现,并搭建信号控制系统,对现实空间的交通设施进行实时控制。本发明通过采用数字孪生处理方式,将采集到的信息对应到虚拟环境中,实现虚实结合,进一步提高基于复杂数据预测交通状态的综合性和准确性,能够更好的对道路交通状态预测和拥堵路段进行优化控制。
