The invention discloses a moving track reconstruction and road matching method, a storage medium and a server, and the method comprises the steps: carrying out the road network matching of collected urban resident multi-source space-time GPS trajectory data in a target region, obtaining road network nodes, and constructing a transition probability matrix between the road network nodes; screening the road network nodes, and extracting key road network nodes in the radiation range of the base station; according to the transition probability matrix between the road network nodes, obtaining a maximum transition probability path and a maximum transition probability between the key road network nodes in the base station switching process, and constructing an optimal path experience track libraryof the key road network nodes; constructing a double-layer road network structure chart according to the optimal path experience track library and a known base station sequence; and according to thedouble-layer road network structure chart and an optimal path experience track library, restoring a maximum real transition probability path between a starting point and an end point between road network nodes. The method is of great significance to alleviation of traffic jam, reasonable traffic planning and guidance of public travel.
Description
technical field [0001] The invention relates to the application field of multi-source trajectory data, in particular to a method for reconstruction of moving trajectory and road matching, a storage medium and a server. Background technique [0002] In recent years, the analysis based on mobile phone signaling data has become an important technology for the analysis of large-scale user travel behavior characteristics and traffic information collection. One of the key technologies that restricts its further development of data value is the road network matching and movement trajectory restoration technology for mobile phone positioning and movement trajectory points. [0003] Limited by the data recording methods of mobile communication service providers, the common mobile phone signaling data is usually a single-source base station source address positioning method. The positioning accuracy of this method is much lower than that of GPS positioning methods. The time granulari...
