| description | The invention discloses a multi-source data fusion method, device and equipment for spatial-temporal characteristics of an expressway. The method comprises the following steps: acquiring panoramic traffic data of the expressway; matching the SCATS ground induction coil data and the portal system data with an expressway road network, and performing double-layer road network division on the expressway road network to obtain traffic area division data and traffic area associated data; obtaining vehicle passing track data based on a space sequence model according to the portal system data and the highway entrance and exit record data; obtaining meteorological change data based on a temporal grid model according to the meteorological data along the highway; and according to the traffic area association data, fusing the traffic state data and the traffic influence factor data of each sub-traffic area to obtain the spatial-temporal characteristics of the expressway. According to the method, various kinds of multi-so |
