Fourteen WTI researchers, affiliated faculty, fellows, and staff have returned from a busy and productive week at the Transportation Research Board (TRB) Annual Meeting in Washington, D.C. The premier transportation research event of the year, the meeting is attended by more than 13,000 transportation leaders, practitioners, and researchers from around the world. The U.S. Secretary of Transportation, Elaine Chao, addressed attendees at the Chair’s luncheon, speaking on initiatives to deploy innovative technologies such as V2X, or “vehicle to everything” communication.
WTI staff played key roles across numerous topics and forums – presenting research at panels and in poster sessions, participating in committees, and leading workshops. One of the highlights was the well-attended workshop on “Rural Transportation for Everyone: Policy and Practice in 2020,” led by Jaime Sullivan.
The Idaho Transportation Department is currently considering wildlife crossing structures for a segment of U.S. 20 near Island Park. High Country News recently published an extensive feature article exploring both support and opposition to this proposal: “When wildlife safety turns into fierce political debate.” WTI Road Ecologist Marcel Huijser was interviewed for the article, discussing the potential role and effectiveness of animal detection systems. The article also cites his research on the costs to society of vehicle crashes with deer and other large mammals.

WOLVERINE TRAPPING: The Journal of Wildlife Management has published “The Sustainability of Wolverine Trapping Mortality in Southern Canada,” by Garth Mowat, Tony Clevenger, and their research team. It summarizes the team’s research study, in which they observed wolverines over a large area of southern British Columbia and Alberta, Canada, used spatial capture‐recapture models to estimate density, and calculated trapping kill rates using provincial fur harvest data. The study was also highlighted in a December feature story by the Wildlife Society: “Are southwest Canada wolverines being overharvested?”

EFFECTS OF ROADS IN LATIN AMERICA. In 2020, the Environmental Impact Assessment Review will publish “Effects of Roads on Terrestrial Vertebrate Species in Latin America,” co-authored by Tony Clevenger. It summarizes a review to qualitatively and quantitatively assess scientific research papers addressing road impacts on vertebrate species in Latin America. The paper also summarizes research gaps and recommends an approach for future research.

NIGHT-TIME SPEED LIMITS: The National Transportation Research Database (TRID) has posted the final report for the project “Effectiveness of Night-time Speed Limit Reduction in Reducing Wildlife-Vehicle Collisions.” For this project, Research Scientist Marcel Huijser and his partners investigated the effects of speed limit reductions at mule deer collision hotspots in Wyoming. The researchers studied the effects of the speed limits on vehicle speeds, on the interactions between wildlife and vehicles, and on the number of observed collisions.

The WTI Road Ecology program, in partnership with the MSU Gianforte School of Computing, has completed a second phase of research on a system to simplify how wildlife vehicle collision (WVC) data is collected and shared among federal agencies.
The research program is sponsored by the National Center for Rural Road Safety, the National Park Service (NPS) and US Fish and Wildlife Service (USFWS) – the federal agencies want to develop and coordinate the use of a WVC Data Collection System with other federal land management agencies, state and local agencies, and other organizations. During Phase 1, Road Ecology researchers Rob Ament, Matthew Bell, and Kelley Hall, collaborating with MSU Computer Science professor Mike Wittie, developed a pilot WVC system called ROaDS – Roadkill Observation and Data System. It collects WVC roadkill observations and is available to all Department of Interior (DOI) agencies and bureaus.
During Phase 2, the research team developed recommendations for preliminary national standards for WVC data collection systems, which will promote collection and sharing of consistent data among agencies and partners. The team also made recommendations to modify the ROaDS survey (used for data collection) so it is shorter, easier to use, and more efficient. As part of the development process, team members determined that ROaDS can provide a valuable research function – it captures the observer’s route, how long it took to complete the route and each individual observation made while on that route. Phase 2 also included outreach activities, in which team members began to engage other agencies and organizations to jointly develop national standards for WVC data collection systems via meetings, presentations, and workshops at national conferences that will be continued in Phase 3.
The Federal Lands Wildlife-Vehicle Collision Data Coordination Project Phase 2 report is available on the WTI website. A new poster, which displays highlights from Phases 1 and 2 and proposed activities for Phase 3, is also available at the WVC Data Coordination Project Phase 2 webpage.
