Velocity-Based Terrain Coefficients for Time-Based Models of Human Movement
Open accessAbstract
Few studies have calculated the relative difficulty of walking across different types of terrain (e.g. grass, asphalt, loose sand, and so on). Nonetheless, these relative values, called terrain coefficients, are integral, alongside slope, for generating computer models of human movement, whether for emergency planning, development, archaeology, the impact of ecological change on migratory patterns or any other purposes. Additionally, the few studies conducted evaluate this relative difficulty through metabolic rate measured through oxygen consumption. We demonstrate that these values are only appropriate for energy-based models (e.g. easiest routes), because it is unlikely that the relationship between metabolic rate and velocity is linear even when terrain is held constant. Rather, our work (returning to four terrains from these earlier studies and adding three additional terrains) investigates the relative effect different terrains have on a person's walking speed, finding the effects to be smaller, with statistical significance occurring on an entirely different scale from previous studies. Therefore, these terrain coefficients should only be used for time-based models (e.g. fastest routes).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
