The invention discloses a digital twin system for an expressway cloud control platform. The digital twin system comprises a middle platform layer, a supporting layer and an equipment layer, the equipment layer is used for collecting real-time traffic data and sending the real-time traffic data to the support layer; the support layer is used for receiving the real-time traffic data, determining a transmission channel type, a transmission resource and a storage mode, and then carrying out classified storage on the real-time traffic data; and the middle platform layer is used for collecting the real-time traffic data, correspondingly processing the real-time traffic data and then outputting a processing result. A simulation scene is closer to a real scene through equal-proportion surveying and mapping and building of a high-precision map and addition and integration of random traffic flows of various traffic participants, and the test efficiency, verification sufficiency and effectiveness are effectively improved; the dynamic traffic demand prediction model is utilized to recognize problems such as traffic jam possibly occurring in the future in advance, so that rapid and scientific decision support is provided for highway emergency disposal, and services are provided for highway operation management.
