An embodiment of the present specification discloses a method and apparatus of outputting a flow direction of a vehicle, a roadside device, and a cloud control platform, and relates to artificial intelligence technology fields such as smart traffic, autonomous driving, and the like. The method of outputting a flow direction of a vehicle includes the following steps of: acquiring a driving trace of a vehicle; acquiring a flow direction curve group corresponding to a road, wherein the flow direction curve group includes at least one flow direction curve characterizing a flow direction of the vehicle; determining similarity between the driving trace and each flow direction curve of the flow direction curve group; and selecting a flow direction curve, which has the highest similarity to the driving trace, of the flow direction curve group as a flow direction of the driving trace to output the flow direction curve. Therefore, the present invention can solve an error caused by the manual calculation of a vehicle flow amount.

    본 출원의 실시예는 차량의 흐름방향을 출력하는 방법, 장치, 노변 기기 및 클라우드 제어 플랫폼을 개시하며, 스마트 교통, 자동 운전 등 인공 지능 기술 분야에 관한 것이다. 당해 차량의 흐름방향을 출력하는 방법은, 차량의 주행궤적을 획득하는 단계; 도로에 대응되는 흐름방향 곡선 집합을 획득하는 단계 - 여기서 흐름방향 곡선 집합은 차량의 흐름방향을 특성화하는 적어도 하나의 흐름방향 곡선을 포함함 - ; 흐름방향 곡선 집합 중의 각 흐름방향 곡선과 주행궤적의 유사도를 결정하는 단계; 및 흐름방향 곡선 집합 중에서 주행궤적과의 최고 유사도를 가지는 흐름방향 곡선을 주행궤적의 흐름방향으로 선택하여 출력하는 단계를 포함하는바, 이로써 수동 방식으로 차량 흐름량을 계산함으로 인해 초래되는 오류를 해결할 수 있다.
