Application Tool for Assessing Wildlife Passage

Recent research resulted in a new tool called the Passage Assessment System (PAS). This tool is designed for highway staff to use to assess how well existing highway structures are likely perform at passing a wide range of wildlife. The result will help direct investments to the highest priority projects and identify opportunities for making modifications to existing structures to facilitate wildlife movements. The PAS was field tested and showed promising results. This study seeks to develop a digital version of the PAS or application for use on a hand held device and a database structure for storing the data entered on hand held units. Accomplishing these objectives will make it easier to use PAS to evaluate existing transportation infrastructure and to store the information for easy access for multiple transportation planning purposes. Field verification of the PAS application would be completed in participating member states.
