Urban Network Analysis Toolbox for ArcGIS Description

The City Form Lab has unveiled an innovative toolbox designed specifically for analyzing urban networks. This groundbreaking ArcGIS toolbox is the first of its kind, featuring centrality tools that facilitate the computation of five distinct graph analysis measures on spatial networks: reach, gravity, betweenness, closeness, and straightness. Additionally, it includes redundancy tools that calculate the redundancy index, identify redundant paths, and assess the wayfinding index. Notably, these tools boast three key features that enhance their effectiveness for spatial analysis in urban street networks. Firstly, they are capable of considering both geometry and topology within the input networks, allowing for the use of metric distance (such as meters) or topological distance (like turns) as impedance factors during analysis. Secondly, in contrast to earlier software tools that only handle two network elements—nodes and edges—the UNA tools introduce a third element: buildings, which serve as the spatial units for all analytical measures. This comprehensive approach not only improves the accuracy of urban analysis but also provides deeper insights into the relationships within urban environments.
