| Abstract: | The features of public-travel traffic information and the impact factors of travel route selection were analysed.A multi-source traffic data fusion mining system framework was designed.A series of key technologies,which include the correlation degree analysis of multi-source data,the hierarchical sub-spatial clustering and co-clustering mining analysis,were studied.The theoretical analysis and field test results show that the system has good processing ability and scalability for multi-source data fusion analysis and dimension reduction. |
