The UNA toolbox version 7 only works in the Windows environment in Rhino. It introduced the following new functionality:

• You can now use custom travel costs on network segments (instead of only distance or segment length) in all UNA analyses, including Accessibilitycalculations, pedestrian flow analyses using the Betweennesstool, Patronage or Closest Facility analyses etc. This means you can account for real-world pedestrian qualities of path segments in all your analyses—their sidewalk dimensions, traffic levels, landscaping, amenity densities etc. We recommend using “distance equivalent” units as custom costs and we provide an Example Exercise and Help Documentation to get started.
• We have replaced the old Betweennesstool with a now default Patronage Betweenness tool, which ensures that you can always model pedestrian trip distribution to multiple competing destinations simultaneously, proportioning the number of journeys to each destination according to accessibility levels. If your Origins only have a single Destination, then Patronage Betweenness still works as well. For researchers, the updated Patronage Betweenness tool also allows pedestrian flow results to be exported to a table, detailing results segment by segment.
• In order to produce more accurate estimates of pedestrian / bike flows, trips can always be estimated along all "plausible" routes that are up to a given percentage longer than the least-cost path, not only the least-cost path.
• We have integrated Import/ Export options for .geojson files so you can more easily bring GIS and WebGIS data to Rhino and export UNA results out to GIS or other mapping tools. See UNA Import and Export tools for more.
• We have spun the Straightnessindex out as a separate tool, and considerably updated it. It now allows you to find Origin-Destination pairs for which the shortest network route is X times longer than the straight-line distance, with X being a user defined factor, and to visualize them. This allows users to quickly identify O-D pairs in spatial networks, where pedestrians may be able to easily see a destination (e.g within a 100m as-a-crow-flies distance), but between which an actual walk is relatively long (e.g. 3X longer).
• Users now have the option to choose between three different types of distance decay rates in Gravityaccessibility analyses, including Linear, Exponential and Logistic This helps researchers tailor their analyses to appropriate assumptions about how pedestrian willingness to walk decreases with distance for different types of destinations. Since the Gravity accessibility is also used as part of Patronage Betweenness and Patronage analyses, the same options are also offered for the latter.
• Accessibility indices (Reach, Gravity) now add the option to measure accessibility to only the Nearest destination, in addition to Alland Radius.
• We have added two new data selection tools that allow you to select geometry objects (both points and curves) according to their UNA attribute values. Select by Value selects objects with a specific attribute value and Select By Rangeselects them by specified ranges of values.
• We have added an ExportO-D tool that allows to you generate a quick travel distance calculations between all Origin-Destination pairs, outputting the O-D cost matrix to a table.
• The Redundant Pathstool can now be used to randomly draw a desired number of route alternatives between O-D pairs from a complete set of route alternatives that are available. This allows researchers to conveniently generate alternative routes between O-D pairs for pedestrian or bike route choice modeling.
• The Bake Weight Colortool can now save analysis result colors out to both point and curve objects, so you can easily keep your pedestrian flow results as Rhino object colors. You can also run the Bake Weight Color based on already saved object attributes, not only current displayed graphic results.
• The Graphic Optionsnow allow you to visualize attribute data for point and curve objects, and to vary not only the DotSize but also the LineWeight of your displayed results. You can toggle the UNA Graphic Options display between three graphic modes: PointWeight (to visualize saved point object attributes), LineWeight (to visualize saved curve object attributes), or Result (to visualize currently active UNA analysis results).
• Various performance updates have been added and some naming conventions in previous tools have been streamlined. And the Help documentation offers Example Exercises for which the datasets are provided with the toolbox download.
