The present disclosure relates to a realtime urban traffic status monitoring method based on privacy-preserving compressive sensing, including the following steps: step S1: dividing vehicle data under privacy preserving into two parts, and sending the two parts to two different road side units (RSU) for preprocessing; step S2: outsourcing, by the two different RSUs, preprocessed vehicle data to two cloud platforms (CP) respectively, and designing a data encryption execution protocol based on a finally expected operation result and interactive operation between the two CPs, to encrypt the data; and step S3: receiving, by a navigation service provider (NSP), encrypted data from the CPs, decrypting the received encrypted data, and estimating an urban traffic status by using a compressive sensing technology. The present disclosure can remarkably enhance a capability of protecting privacy of vehicle data, ensure rapid and accurate data processing, reduce energy consumed for urban traffic estimation, and shorten required traffic estimation time.
