The invention relates to the technical field of intelligent traffic systems, in particular to a multi-source data fusion system in urban traffic big data processing. The system comprises a data acquisition module used for acquiring traffic data information from different data sources; a data processing module used for preprocessing the traffic data information; a data extraction module used for performing feature extraction on the preprocessed traffic data information to obtain traffic feature data; a data fusion module used for fusing the traffic characteristic data to generate traffic fusion data; and a data analysis module used for dividing urban traffic into a plurality of areas, obtaining road section traffic flow information of each area, performing centralized processing with the traffic fusion data, performing analysis and evaluation, and outputting traffic evaluation data information. According to the method, through fusion of traffic data information of multiple data sources, the final fusion precision of multi-source data in urban traffic big data processing can be remarkably improved.
