Given a pre-computed travel cost matrix\nand a land use dataset (containing for example the location of\njobs, healthcare and population), the package allows one to\ncalculate accessibility levels, and accessibility poverty and\ninequality. The package covers the majority of the most\ncommonly used accessibility measures (such as cumulative\nopportunities, gravity-based and floating catchment areas\nmethods), some cutting edge measures proposed in the literature\n(e.g. balancing cost and constrained accessibility) as well as\nthe most frequently used inequality and poverty metrics (such\nas the Palma ratio, the concentration and Theil indices and the\nFGT family of measures).", "License": "MIT + file LICENSE", "URL": "https://github.com/ipeaGIT/accessibility,\nhttps://ipeagit.github.io/accessibility/", "BugReports": "https://github.com/ipeaGIT/accessibility/issues", "VignetteBuilder": "knitr", "RdMacros": "Rdpack", "Encoding": "UTF-8", "NeedsCompilation": "no", "Roxygen": "list(markdown = TRUE)", "RoxygenNote": "7.3.3", "Config/pak/sysreqs": "cmake make libicu-dev libuv1-dev", "Repository": "https://ipea.r-universe.dev", "Date/Publication": "2026-05-12 13:01:55 UTC", "RemoteUrl": "https://github.com/ipea/accessibility", "RemoteRef": "HEAD", "RemoteSha": "ccc45f68df2542f3830520d3657bf8281790fdc6", "Packaged": { "Date": "2026-05-14 07:55:45 UTC", "User": "root" }, "Author": "Rafael H.
