WORLAND, Wyo. (AP) — The Wyoming Department of Transportation is using reflector poles in several areas in the state to see if they help prevent wildlife/vehicle collisions.

WYDOT spokesman Cody Beers tells the Associated Press the goal is to determine if the reflectors are instrumental in keeping deer off the highway and to figure out if there's a pattern to the animal crossings. The poles are sometimes covered to see how the deer react to not having the reflections of the headlights, and the display is switched each month.

The poles have been installed along roads between Kirby and the Wedding of the Waters near Thermopolis, along a section between Basin and Greybull, and near Riverton.

The study is being conducted by the Teton Science School near Jackson Hole.
