The next navigation section that the user terminal enters after passing through the current navigation section may refer to a section that the user terminal needs to enter immediately after passing through the current navigation section, that is, the current navigation section and the next navigation section are two continuous sections that are connected end to end, or may refer to a section that the user terminal does not need to enter immediately after passing through the current navigation section, that is, the current navigation section and the next navigation section are separate and discontinuous two sections, and a certain interval is provided between the two sections.
According to the navigation path planning method provided by the embodiment of the application, in the driving process of a user side on a current navigation road section, a target navigation route from a road section end position to a trip end position of the user side is determined according to the road section end position of the current navigation road section and the trip end position of the user side; and determining the first navigation road section of the target navigation route as the next navigation road section which the user terminal enters after passing through the current navigation road section, and sending the navigation information of the next navigation road section to the user terminal.
Therefore, the whole route of the user can be divided into different road sections, and in the user side traveling process, the navigation information of the user side on the next navigation road section is gradually determined according to each road section, so that the generated navigation path and the navigation information sent to the user can be more fit with the real-time road condition, the reliability of user side navigation is higher, the convenience and smoothness of user traveling are ensured, and the user experience is favorably improved.
