Understanding the interplay between urban segregation and accessibility to services with network analysis
Fig 2
Example of a node n and its closest Points of Interest (PoIs).
Three example service categories are shown: purple triangles, blue diamonds, and green squares. The closest PoIs in each category are respectively i (at walkable distance of 5 minutes), a (at 7 minutes), and x (at 10 minutes). In this example, the PoI-proximity because residents in n can walk to a PoI for each of the given categories within 10 minutes. Equivalently, the largest isochrone for n that includes at least one service in each category is
