Urban Network Analysis Toolbox for ArcGIS Reviews

Urban Network Analysis Toolbox for ArcGIS Description

The City Form Lab has created a state of the art toolbox for urban network analysis. The ArcGIS centrality toolbox is the first of its type. It can be used to calculate five types of graph analysis measures on spatial network: reach, gravity, betweenness; closeness and straightness. Redundancy tools also calculate the redundancy index and redundant paths as well as the wayfinding index. These tools have three key features that make them ideal for spatial analysis of urban street networks. They can account for both topology and geometry in the input networks using either metric distance (e.g. Meters) or topological distance (e.g. The analysis uses impedance factors such as turns. Second, unlike other software tools that only operate with two network elements (edges and nodes), UNA tools include a third element, buildings. These are used to calculate all measures.
