  • Publication number: 20200312147
    Abstract: A method and an apparatus for displaying a travelling strategy based on public transportation can improve user travel experience. When the user appears in a first preset range of the starting public station, the first public transportation travelling strategy can be automatically acquired and displayed on the designated interface for the user's reference. The user does not need to take the initiative to perform multiple steps to check the travelling strategy displayed on the designated interface, which can have lower requirements on the user and can improve the operation efficiency.
