The invention discloses a digital twinning-oriented road operation data estimation method and device, and the method comprises the steps: constructing a digital twinning road traffic system based on actual road data, and building a mapping relation between a vehicle on an actual road and a virtual road of the digital twinning road traffic system; constructing an intelligent interpolation data set based on the driving state data of each vehicle collected by each road sensor discontinuously arranged on the actual road, and calculating the road running state estimation data of any position of the virtual road according to the intelligent interpolation data set; and generating a digital twin road traffic system state diagram according to the running state estimation data of each road, and displaying the digital twin road traffic system state diagram to a vehicle in real time. According to the invention, intelligent interpolation is carried out on the vehicle driving state data collected by the road sensor arranged on the roadside, online verification is carried out on the vehicle passing in real time, the interpolation data is dynamically corrected, and accurate estimation of the road operation data is realized.
本发明公开了一种面向数字孪生的道路运行数据预估方法及装置,该方法包括基于实际道路数据构建数字孪生道路交通系统,建立车辆在实际道路和数字孪生道路交通系统的虚拟道路上的映射关系;基于在实际道路上间断设置的各道路传感器采集的各车辆行驶状态数据构建智能插补数据集,并根据智能插补数据集计算虚拟道路任意位置的道路运行状态预估数据;根据各道路运行状态预估数据生成数字孪生道路交通系统状态图,并向车辆实时展示所述数字孪生道路交通系统状态图。本发明实现了通过路边设置的道路传感器采集的车辆行驶状态数据进行智能插补,并通过实时通过的车辆进行在线校验,进而对插补数据进行动态修正,实现了对道路运行数据的精准估计。
