Algorithm for efficient identification of enclosed cyclic neighbourhoods within networks, and functions for aggregating neighbourhoods according to network properties.

One example application of the package is the automated identification of so-called “Low-Traffic Neighbourhoods” (LTNs), which can be identified through a dedicated function, ltns(). These are identified by first decomposing a network into its constituent “neighbourhoods” of enclosed polygons. The ltns() function then successively aggregates adjacent neighbourhoods according to various criteria useful for defining and identifying Low Traffic Neighbourhoods.
