It provides network processing tools including graph consolidation and simplification, route enumeration algorithms, and efficient All-or-Nothing assignment. Built on fastverse libraries (collapse, kit, igraph, geodist, mirai) with custom C code, it handles both small networks (Africa's 1,379-node road network) and large ones (US FAF5's 487,384 links). The package uses data frames for graphs and OD matrices, supports multimodal networks, and enables probabilistic traffic flow assignments with customizable parameters. ## Full article daily.dev links to this article rather than hosting it.
