The "Urban Network Analysis User Guide: Tools For Modeling Pedestrian and Bicycle Trips in Cities" provides an in-depth introduction to spatial network analysis in Rhinoceros 3D. Part One introduces three case-studies, which demonstrate how the UNA tools have been used in practice to inform real-world urban design and transportation planning decisions. Part Two contains a technical user guide, which first covers the installation requirements and then discusses each of the UNA tools in detail. A Frequently Asked Questions section offers tips for troubleshooting. A short introductory video about the UNA toolbox, as well as a few screen-recorded tutorials can be found online at: http://cityform.gsd.harvard.edu/projects/una-rhino-toolbox.
