Because of their position in the center of the traveled right-of-way, median barriers could affect wildlife movement across the right-of-way, decreasing wildlife connectivity. This project team coordinated and met with staff from several Caltrans Districts to gain understanding of their issues related to median barriers and wildlife permeability.

The Wildlife Crossing Calculator (WCC) includes a set of analytical tools to help estimate the costs to the public of crashes involving wildlife and compare those costs with the costs and benefits of wildlife crossing mitigations.

In this study researchers evaluated the effectiveness of wildlife crossings in mitigating traffic noise and light.
