A method for processing measurement data of a vehicle for determining the start of a search for a parking space includes acquiring journey data vectors, each containing information about a speed, position data and a time of acquisition of the speed and the position data, and establishing a feature vector at each time of acquisition of the journey data vectors, where the information about a current and a previous journey data vector is processed, and where the feature vector comprises as feature components at least one item of speed information and one item of path information. The method also includes classifying each feature vector, where a first traffic category, which represents a vehicle journey, or a second vehicle category, which represents parking space-seeking traffic, is assigned to each feature vector, and where a probability is established, which specifies the probability with which the first or the second traffic category is to be assigned to the feature vector. In addition, the method includes segmenting the feature vectors over the time profile of the established traffic categories, where there is a subdivision of the journey from the start to the last acquisition of a journey data vector into two segments in accordance with the determined traffic categories of the feature vectors and the transition from one segment into the other segment represents the start of the search for a parking space. |
