The invention discloses a traffic analysis model correction method and device based on digital twinning, relates to the technical field of traffic control systems, and solves the problem that the accuracy of traffic analysis model correction is limited by the existing traffic analysis model correction technology. The traffic analysis model is established through the digital twinning technology, synchronization of the traffic analysis model and traffic operation real data is realized through the sensor, wherein the accuracy of the traffic analysis model is calculated according to the preset loss function, and the operation prediction value of the traffic analysis model is compensated and corrected. The traffic analysis model is trained through samples, parameters of the traffic analysis model are adjusted, and a measurement matrix of a preset loss function is updated. According to the invention, the input parameters of the model are adjusted based on the digital twinning technology and the loss function, the model is continuously optimized, and therefore data measured by the traffic analysis model approaches real traffic operation data.
