Abstract

This paper outlines a simple strategy for recognising prototypical cases of urban roads given only their geometric forms. Two new indicators, namely exits and occupancy, are used together with average width to label regions as roads. Even in its present simplistic form, the methodology proposed here proved to be useful for identifying prototypical cases. It is equally useful for flagging some roads as untypical. These were labelled as roads by a previous study on road extraction which exploited available semantic information. However, owing to the absence of logical links, some roads became combined with neighbouring regions making them untypical. The recognition strategy therefore provides an additional means for validating topographic data.
