Wildlife mortality caused by vehicles is a serious conservation and economic problem as collisions with large mammals are global, persuasive and increasing. This study reviewed the U.S. and European scientific literature pertinent to mitigating the effects of ungulate-vehicle collisions. The paper presents an analysis of ungulate movement and behavior in relation to roads for the purpose of developing general conclusions about locating high frequency collision areas, and documents some successes in reducing these collisions with fencing, modified fencing, and grade separation via crossing structures. Several case studies are also presented to illustrate animal detection driver warning systems, technology based deployments, applied to the problem of ungulate-vehicle collisions. The paper emphasizes the need for more sound statistical design in determining efficacy of treatments.
