• Description:
  Swareflex wildlife warning reflectors were installed on a four-mile section of road near Denver. Two half-mile test sections were alternately covered and uncovered for a three-month period to see if any significant change in deer-vehicle accidents could be detected. No accidents occurred in the test sections during the evaluation period. The cover/uncover evaluation method proved too costly for the limited budget of this study. Photometric measurements of the reflectors have been made using vehicle headlights as the light source. The use of wildlife warning reflectors should be discontinued until more evidence is available on their effectiveness--especially on mule deer. A regional pooled-fund study should be started to investigate the effect of the reflectors on mule deer. This needs to be a large-scale effort to obtain results in a short period of time and to ensure validity.
