About Urban Network Analysis Toolbox for ArcGIS
The City Form Lab has released a state-of-the-art toolbox for urban network analysis. As the first of its kind, the centrality tools this ArcGIS toolbox can be used to compute five types of graph analysis measures on spatial networks: reach; gravity; betweenness; closeness; and straightness. Redundancy tools additionally calculate the redundancy index, redundant paths, and the wayfinding index. The tools incorporate three important features that make them particularly suited for spatial analysis on urban street networks. First, they can account for both geometry and topology in the input networks, using either metric distance (e.g. meters) or topological distance (e.g. turns) as impedance factors in the analysis. Second, unlike previous software tools that operate with two network elements (nodes and edges), the UNA tools include a third network element, buildings, which are used as the spatial units of analysis for all measures.
