Affordance-Based Individuation Of Junctions In Open Street Map, Simon Scheider, Jörg Possin

Journal of Spatial Information Science

We propose an algorithm that can be used to identify automatically the subset of street segments of a road network map that corresponds to a junction. The main idea is to use turn-compliant locomotion affordances i.e. restricted patterns of supported movement in order to specify junctions independently of their data representation and in order to motivate tractable individuation and classification strategies. We argue that common approaches based solely on geometry or topology of the street segment graph are useful but insufficient proxies. They miss certain turn restrictions essential to junctions. From a computational viewpoint the main challenge of affordance-based individuation …
