Figure 7 from Inman and others 2024. Traffic and wildlife vehicle collisions.

Fig. 7. A) Observed relationship between number of reported vehicular wildlife collisions (WVCs) in Wyoming, USA and annual average daily traffic (aadt) of all-vehicles from a generalized linear mixed effects model. The greatest number of reported WVCs were expected on roads with all-vehicle traffic volumes between 10,000 and 13,000 aadt, given all other factors. B) Traffic volume threshold hypothesis wherein the number of individuals that can successfully cross a road (dashed) decreases as traffic volume increases, but so too does road avoidance behavior (dotted). This results in a peak of observed WVCs (solid) at moderate levels of traffic volume.
