Mining the Relationship between Spatial Mobility Patterns and POIs

Figure 1

Illustration of the network and communities (this is the prototype proposed by Liu et al., 2015). To construct a network based on mobility flows, the study area is divided into small regions (a) with each small regions corresponding to a node in the network. A directed edge or linkage existed between two nodes if there are mobility flows from one node to the other. The weight of an edge equals the volume of mobility flows represented in (b, c). Graphic (d) provides an illustration of the communities detected from a network, which is divided into four parts (depicted by four circles) in which the subnetworks had relatively dense connections. The community detection result corresponds to closely connected subregions (e).
