Abstract: A method and apparatus for prompting navigation information. The method includes: acquiring, when a user is in an underground vehicle area, traffic behavior statuses of an underground vehicle at stops on a preset navigation route; determining, in response to the traffic behavior status of each stop of adjacent stops on the navigation route being consistent with a first preset traffic behavior status, a base station corresponding to a latter stop in the adjacent stops as a reference station; determining a location of a preset stop on the navigation route, based on a location of the reference station and locations of base stations provided at the stops; and outputting, in response to the traffic behavior status of the underground vehicle at the preset stop being consistent with a second preset traffic behavior status, prompt information for getting off.
