Abstract: A traffic prediction method includes performing traffic autonomous zone division on a to-be-predicted geographic area based on geographic information data of the geographic area and crowd flow data of the geographic area to obtain a plurality of sub-areas; determining, for any sub-area, a crowd flow motif in the sub-area based on geographic information data of the sub-area and crowd flow data of the sub-area, where the crowd flow motif indicates a multi-point crowd motion pattern in the sub-area; determining a crowd flow feature of the sub-area based on the crowd flow motif; and predicting data traffic of the sub-area based on the crowd flow feature of the sub-area to obtain a data traffic prediction result of the sub-area.

Abstract: In a data processing method, a processing device performs encoding, based on spatial position data and time position data of a trajectory point of a trajectory according to an encoding rule of a hybrid code of a preset level in an index database, to obtain a hybrid code of each trajectory point. The hybrid code includes temporal information and spatial position information of the trajectory point. The processing device then queries a similar trajectory in the index database based on the hybrid code of each trajectory point. The index database includes hybrid codes of a plurality of levels, and the index database includes hybrid codes with trajectory information that includes a trajectory identifier and a trajectory length.
