1. A navigation apparatus for providing a navigation path for a target vehicle, comprising at least one processor and at least one memory, wherein the at least one memory is configured to store program instructions that, when executed by the at least one processor, cause the navigation apparatus to:
receive first location information of the target vehicle sent by a high-definition map server, wherein the first location information comprises lane information of a first location at which the target vehicle is currently located, wherein the first location information further comprises lane-level road information in a first preset peripheral region range of the first location at which the target vehicle is currently located, the first preset peripheral region range being based on a speed of the target vehicle, and wherein the first location information further comprises lane availability information in the first preset peripheral region range of the first location of the target vehicle, the lane availability information including availability information indicating whether each lane of lanes of a road in the first preset peripheral region range is available, the availability information of each lane including a corresponding congestion status for each lane of the lanes of the road; and
determine the navigation path based on the first location information and a destination,
wherein the determination of the navigation path based on the first location information and the destination comprises:
generating an initial navigation path based on the first location information and the destination;
sending the initial navigation path to the high-definition map server;
receiving lane-level road information of the initial navigation path returned by the high-definition map server based on the initial navigation path, wherein the lane-level road information of the initial navigation path comprises lane-level road information of a road section of the initial navigation path; and
determining the navigation path based on the lane-level road information of the initial navigation path.
