Summary In this thesis, a new method for the extraction of road networks in suburban areas from optical aerial images is developed. The road extraction method is region-based; road regions are extracted from a segmented image and combined to create a road network. Knowledge about roads pertaining specifically to suburban areas is used in the entire extraction process. In this way, the characteristics of suburban areas are considered, for example the fact that road markings are relatively rare in suburban areas, as opposed to inner city areas.
