1. A generation method for a navigation performed by processing circuitry, the method comprising:
acquiring a planned driving path, the planned driving path comprising a first intersection and a second intersection to be passed successively;
determining, a distance between the first intersection and the second intersection;
in response to the determined distance between the first intersection and the second intersection being less than a distance threshold,
acquiring lane information of a connecting road between the first intersection and the second intersection, the lane information including a distribution of lanes on the connecting road and at least one driving restriction corresponding to at least one of the lanes on the connecting road;
determining a recommended driving lane on the connecting road between the first intersection and the second intersection based on the lane information and a planned driving direction at the second intersection;
generating, before a vehicle passes through the first intersection, the navigation prompt message indicating the recommended driving lane, the navigation prompt message guiding a driver of the vehicle to drive on the recommended driving lane; and
outputting the navigation prompt message to the driver of the vehicle.
