Abstract
A display device is for displaying a travel route, the travel route including a chain of route elements, and each route element having a measured value and a quantity of attributes. The display device includes a partial chain ascertainer, a calculation unit, a sorter, and a display unit. For each attribute of at least one route element the partial chain ascertainer determines a continuous partial chain of route elements of maximum length, including the route element, that have an identical attribute. For each partial chain, the calculation unit calculates an individual total measured value from the measured values of the route elements of the partial chain. The sorter sorts the quantity of attributes for the at least one route element into a sequence of hierarchical levels according to a quantitative relation of the total measured values of the partial chains of the attributes, and the display unit displays the attributes of the at least one route element in a hierarchical representation in accordance with the hierarchy levels.
