Abstract (en)
The disclosure relates to the field of intelligent driving, and specifically provides a method, apparatus, storage medium, and a vehicle for predicting traffic flow, comprising: selecting a target vehicle and a reference vehicle, and obtaining corresponding vehicle information; determining whether the target vehicle is in a following state based on the vehicle information and a non-free driving state of the target vehicle relative to the reference vehicle, and predicting traffic flow of a target lane. By the method of the disclosure, whether a moving speed of the target vehicle can represent an average speed of vehicles in the lane is determined based on a car-following theory, thereby obtaining more accurate lane-level traffic flow information and providing more accurate data support for intelligent driving.
