Abstract: A method includes obtaining a first time period during which a user arrives from a first geographical location to a second geographical location, and collecting, in the first time period, accelerations in a horizontal direction. The method further includes determining, based on an acceleration change in the horizontal direction, a second time period from a moment at which the user departs from the first geographical location to a moment at which a bus begins to move after the user takes the bus. The method further includes collecting a plurality of geographical locations of the user in the second time period. The method further includes performing clustering on the plurality of geographical locations to determine a geographical location whose collection quantity meets a condition. The method further includes using the geographical location whose collection quantity meets the condition as a geographical location at which the user takes the bus.
