An embodiment of the present application discloses a method, apparatus, roadside device, and cloud control platform for outputting a traffic flow direction, and relates to a field of artificial intelligence technology, such as smart transportation and automatic driving. The method for outputting a traffic flow direction comprises the steps of: obtaining a driving trajectory of a vehicle; obtaining a flow direction curve set corresponding to a road, wherein the flow direction curve set includes at least one flow direction curve characterizing the traffic flow direction; determining a degree of similarity between each flow direction curve in the flow direction curve set and the driving trajectory; and selecting and outputting a flow direction curve having the highest similarity with the driving trajectory as the flow direction of the driving trajectory from among the flow direction curve set. Accordingly, the present application can solve an error caused when calculating a vehicle flow amount in a manual way.

    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.
