The invention belongs to the technical field of urban road traffic state sensing, and particularly relates to an urban viaduct traffic state sensing method based on a bayonet and an HADOOP technology. The method comprises the following steps of obtaining bayonet data; using the HADOOP technology for storing data; screening the bayonet data in the statistics period; matching the bayonet data with a viaduct entering and exit ramp; calculating the traffic state of the viaduct. The method has the advantages that the road section traveling time and the average route speed are used as the basis for realizing the urban viaduct traffic state sensing, the traffic state sensing efficiency and the timeliness are improved through fast storage retrieval, and the basic guarantee is provided for an urban viaduct traffic manager to fast and effectively master the traffic state.
