Abstract: This paper proposed a method which aims to avoid the conflicts caused by the simplification of road networks by using road bends. First, using road bend as basic unit to analyze the morphological changes of the curve line, different types of the spatial conflicts in road simplification process were studied. Second, the identification rules of different types of conflicts were studied based on the special relations between road bends and other features. Finally, using the controllability of road bends and the indirect simplification by using bend groups, to avoid the conflicts. Comparing results illustrated that this method can effectively identify and avoid the special conflicts during the road simplification and maintaining the special relation consistency of the data.

Key words: map generalization, road simplification, spatial conflict, curve mode
