Embodiments of the present disclosure disclose a method and apparatus for outputting a vehicle flow direction, a roadside device, and a cloud control platform, and relate to the technical field of artificial intelligence such as intelligent traffic and autonomous driving. The method for outputting a vehicle flow direction includes: acquiring a traveling trajectory of a vehicle; acquiring a flow direction curve set corresponding to a road, the flow direction curve set including at least one flow direction curve representing the vehicle flow direction; determining a similarity between each flow direction curve in the flow direction curve set and the traveling trajectory; and selecting a flow direction curve having a highest similarity to the traveling trajectory from the flow direction curve set as a flow direction of the traveling trajectory, and outputting the flow direction of the traveling trajectory, so that an error caused by manually counting the traffic flow can be solved.
