The invention discloses a method and a device for determining a traffic condition of a road section. The method comprises the following steps: according to car positions, collected at multiple collection moments in a preset time bucket, of floating cars on a to-be-determined road section, determining car cluster center points, respectively at the multiple collection moments, of the to-be-determined road section; according to the distance between the two car cluster center points at every two adjoining collection moments on the to-be-determined road section and the time interval between every two adjoining collection moments, determining the speed of each car cluster center point in the driving direction of the to-be-determined road section; according to the magnitude relation between the speed of each car cluster center point and a preset speed threshold value, determining the traffic condition of the to-be-determined road section in the preset time bucket. Compared with the prior art, the method provided by the invention has the advantage that the accuracy of determining the traffic condition according to the driving data of the floating cars is improved.
