The invention relates to an urban-level digital twin traffic system, and the system comprises a data planning and pushing unit which is configured to obtain data of third-party road test monitoring equipment, and the data comprise road data and vehicle data in a real space; the vehicle model module is configured to make model data of the vehicle in the virtual three-dimensional scene; the model scene space coordinate matching module is configured to obtain the data of the data planning and pushing unit and the vehicle model module, perform spatial position calibration on the road model, and enable the road data in the real space to be matched with the coordinates of the road model; and the data fusion module is configured to divide the road into a plurality of sub-road sections, acquire data of the third-party road test monitoring equipment in each sub-road section, perform interpolation calculation on the acquired data, display the data in an animation form, execute the animation and realize display of virtual and real mapping of the traffic vehicle. According to the invention, the problems of inaccurate space coordinates of virtual and real scenes, inconsistent model and actual vehicle information and the like in the prior art are solved.
