This dataset represents commuter flows (work travel) between origin and destination zones (see cents()). The data is from the UK and is available as open data: https://wicid.ukdataservice.ac.uk/.

data(flow)

Format

A data frame with 49 rows and 15 columns

Details

The variables are as follows:

  • Area.of.residence. id of origin zone

  • Area.of.workplace id of destination zone

  • All. Travel to work flows by all modes

  • [,4:15]. Flows for different modes

  • id. unique id of flow

Although these variable names are unique to UK data, the data structure is generalisable and typical of flow data from any source. The key variables are the origin and destination ids, which link to the cents georeferenced spatial objects.
