Map element change detection method based on driving behavior data

The invention discloses a map element change detection method based on driving behavior data. The method comprises the following steps: step 1, acquiring driving behavior original data; 2, map data and driving behavior original data are combined, driving behavior statistical data are generated through statistics and calculation, and the driving behavior statistical data are associated with map elements; 3, element change confidence information is generated according to the structure of the driving behavior statistical data, the element change confidence information is used for judging whether map elements are likely to change or not, and the element change confidence information is associated with the map elements; and 4, storing the driving behavior statistical data and the factor change confidence degree information in the map data. A new type of map data change detection information based on the driving behavior statistical data can be added to the map. According to the embodiment of the invention, the key
