Abstract: A method for operating a transportation vehicle wherein an image capturing unit is used to generate an optical image of an upcoming roadway lying ahead in the direction of travel of the transportation vehicle. The image is used to ascertain an ego lane of the roadway assigned to the transportation vehicle and an upcoming profile of the ego lane. At least one item of meta information that influences the detection of the ego lane and/or of the upcoming profile of the ego lane is captured. Swarm data pertaining to the roadway are retrieved from a database, a comparison lane of the roadway and a comparison profile of the comparison lane are derived from the swarm data, and the at least one item of meta information, the upcoming profile and the comparison profile are used to ascertain an uncertainty factor for the image from the image capturing unit.
