Trip duration drives shift in travel network structure with implications for the predictability of spatial disease spread
Fig 2
Travel network topology shifts from heterogeneous to homogeneous as trip duration increases.
Maps of Namibia with travel volumes between districts that fall within three broad intervals of trip duration: A) 1–3 days, B) 7–14 days, and C) 30–60 days. For comparison, connectivity is defined as relative edge weight from 0 to 100%, which is calculated by scaling trip volume along the edges in each sub-network by the overall maximum trip volume observed in the full travel network. District centroids (nodes of the network) are indicated by the white circles.
