Abstract: Implementations of path planning methods, devices, and systems are disclosed. In an implementation, a first velocity set of a target vehicle is determined according to a first velocity set of a reference vehicle of the target vehicle. The first velocity set includes velocity information in one-to-one correspondence to at least one time point. The first segment is a next segment of a current driving segment of the target vehicle, and the reference vehicle is a preceding vehicle of the target vehicle; and sending the first velocity set of the target vehicle to the target vehicle. Lane-level path planning can be implemented for a road lane, a ramp, and a crossroad etc. By planning a driving velocity of a vehicle in advance, overall traffic efficiency can be improved and a possibility of traffic accidents can be reduced.
