Searching for 2D Spatial Network Holes

摘要

Research involving different forms of networks, such as internetudnetworks, social networks, and cellular networks, has increasingly become anudimportant field of study. From this work, a variety of different scaling laws haveudbeen discovered. However, these aspatial laws, stemming from graph theory, oftenuddo not apply to spatial networks. When searching for network holes, results fromudgraph theory frequently do not correlate with 2D spatial holes that enforceudplanarity. We present a general approach for finding holes in a 2D spatial network,udand in particular for a network representing street centrelines of an area inudWashington, D.C. This methodology involves finding graph holes that can beudrestricted to 2D spatial holes by examining topological relationships betweenudnetwork features. These spatial network holes gain significance as the number ofudedges encompassing the hole, and the length of these edges increase. For thisudreason, our approach is designed to classify these holes into different sets based onudthe number of edges found and the length of those edges. The results of thisudapplication provide valuable insights in the nature of the network, highlightingudareas that we know from experience are poorly connected and thus suffer from lowudaccessibility.
