title: 'traveltime: Calculate Travel Times Over Space'
version: 1.0.0
doi: 10.12688/gatesopenres.16356.1
abstract: Calculate travel time across a landscape from a set of user-specified locations,
  over a friction surface describing the time taken to cross each cell. Implements
  the least-cost travel time approach of Weiss et al. (2018) <https://doi.org/10.1038/nature25181>
  and Weiss et al. (2020) <https://doi.org/10.1038/s41591-020-1059-1>, and provides
  convenient access to their global walking and motorised friction surfaces via the
  'malariaAtlas' package. Travel times are computed with 'terra'. See Ryan et al.
  (2025) <https://doi.org/10.12688/gatesopenres.16356.1> for further details.
