  1. WF = wildlife fence, MEAS = countermeasure (automatic speed camera, radio or warning sign), FOR = forest or open, and measure point (where the countermeasure was employed). MARS analysis was performed on three different datasets for each AVC countermeasure (automatic speed camera, radio, warning sign). Speed data includes distances according to Fig. 2. Results related to the factor participant were excluded from the table for clarity
