description A method for producing a lane-accurate road map. The method includes providing a digital road-accurate road map, providing a trajectory data record, identifying at least one road with segmenting of the road-accurate road map into at least one road segment, modeling the road segment in a road model, the road model having parameters for describing lanes of the road, random variation of parameter values of at least a part of the parameters of the road model through random selection of a change operation of the road model, and assigning at least a part of the trajectory data of the trajectory data record to the road model with ascertaining of at least one probability value for the road model. Based on the ascertained at least one probability value, optimal parameter values of the road model are ascertained, and based on this a lane-accurate road map is produced.
