Multi-dimensional transportation data fusion and data quality detection method

The invention discloses a multi-dimensional transportation data fusion and data quality detection method. The method comprises the following steps: S1, data collection: acquiring original travel data of different types of vehicles from different platforms and systems, wherein the method comprises a data acquisition component, a data storage component and a data preprocessing component; S2, data fusion including three levels of data level fusion, feature level fusion and decision level fusion; and S3, fusion data quality detection. According to the invention, more objective and accurate passenger travel rule analysis, bus section passenger flow prediction, taxi passenger-carrying route recommendation and sharing of multi-dimensional transportation fusion data can be carried out by using the multi-dimensional traffic travel data, a set of double-closed-loop fusion data quality detection method is provided, and the data quality is ensured to the greatest extent; and the invention solves the problems that: data a
