Wildlife crossings don't just protect animals. They can also mitigate problems related to wildlife-vehicle collisions (碰撞) and save significant money for a community.

Wildlife crossings are man-made structures that help animals move safely around their habitat. They are often paths under or over another existing road or railway, or underground passages for animals to get past for food or avoiding attacks.

Some animals are unable to migrate to survive. People still rely on highways for business and travel, and animals continue to have mobility needs for survival, though. When new roads are built, animals living in a part of their habitat can greatly increase the number of wildlife- vehicle collisions while trying to cross the new barriers.

In a new study, Wisnu Sugiarto, a Washington State University economics doctoral student, examined data for 13 of the 22 wildlife crossings, including bridges and underpasses, in the Washington State. He compared the number of wildlife-vehicle collisions each year before and after the construction of a wildlife crossing. He considered the area within 10 miles of a crossing.

Then he compared his analysis to a separate area in the state with no crossings at all. "The findings reported that wildlife crossing structures reduced the number of wildlife-vehicle collisions by one to three accidents on average per mile per year," Sugiarto said. "Therefore, building wildlife crossing structures is typically an essential and effective strategy to reduce wildlife-vehicle collisions. "

"Prior to working on this research, I wasn't aware of any strategies to reduce wildlife vehicle collisions. I also thought we couldn't do much about it, partly because we wouldn't be able to communicate with wildlife and control their movement," Sugiarto added. "However, it turns out that there are multiple strategies to deal with issues related to wildlife-vehicle collisions and we can do something about them."

It is reported that the government has invested $ 350 million over five years for the construction of wildlife crossings. Every wildlife crossing offers a mean benefit of between $235,000 and $443,000 each year.
