1. A system for pre-processing road segment data, comprising:

  • a first storage unit containing road segment data;

    a second storage unit containing tiling definition data;

    a working memory unit for storing a subset of the road segment data and a subset of the tiling definition data; and

    a processing unit adapted to process data stored in the working memory unit and to determine a rank information of a road segment based on the tiling, where the rank information quantifies the relevance of the road segment for optimum routes connecting tiles of the tiling.
