From: Uncovering the internal structure of Boko Haram through its mobility patterns
For each combination of the daily speed ν and the maximum distance between two events μ, a spatial network was constructed. We measure the percentage of trips completed inside the same node (top), the percentage of trips which happen within the top 1% of the edges (middle) and the percentage of present edges (bottom). With a speed of ν = 60 kilometres and a maximum distance of μ = 180 kilometres, roughly 8% of the trips happen inside the nodes, nearly 50% of the trips happen within the top 1% of the edges and only 12% of the edges are present
