WTI Research Scientist Tony Clevenger has co-authored a journal article on the impacts of road expansion on cheetah populations. In June, the Journal for Nature Conservation will publish “Road expansion: A challenge to conservation of mammals, with particular emphasis on the endangered Asiatic cheetah in Iran.” The article summarizes a study to identify hotspot locations along an extremely high-risk road for mammals in northeast Iran (Touran Biosphere Reserve [TBR]) and proposes mitigation measures for mammals such as the Asiatic cheetah and Persian gazelles. The full article is currently available on the Science Direct website.

Congratulations to the City of Bozeman, one of only three communities across the nation selected to receive State of the Art Transportation Trainings from Transportation for America (T4America). WTI’s Rebecca Gleason served on the team that developed the successful grant application, led by Cathy Costakis of the Montana Nutrition and Physical Activity Program along with Randy Carpenter of Future West, Jim Madden of Mountain Time Arts, with support from Bozeman Mayor Cyndy Andrus. Through this program, Bozeman will receive technical training workshops from T4America on how to partner with local arts leaders and organizations to develop “out of the box” transportation solutions and broaden public support for current or future projects. Bozeman hopes to engage its vibrant arts community into transportation planning efforts across the Gallatin Valley, and in particular, into initiatives to create a first-class regional transit system as the region grows. “We are excited to be selected for this unique program, which is great fit for Bozeman given how rapidly our population is growing,” said Rebecca.
David Kack, WTI’s Mobility and Public Transportation Manager, traveled to Washington D.C. last week to participate in the First Annual National Mobility Summit. This event, sponsored by Carnegie Mellon University, was designed to enable a discussion among all of the University Transportation Centers (UTCs) that focused on the topic of mobility. Nine UTCs representing 48 colleges and universities attended, along with representatives from USDOT, the Department of Energy, and several other mobility related entities (for a total attendance of about 60 people).
David gave a ten-minute presentation on both the Small Urban and Rural Livability Center (SURLC), as well as the Small Urban, Rural and Tribal Center on Mobility (SURTCOM). During a reception, David displayed a Poster and discussed the challenges of providing mobility in rural and tribal areas. Carnegie Mellon University expects this to be an annual event for the next four years.
Ultra-high performance concrete (UHPC) has mechanical and durability properties that far exceed those of conventional concrete. However, using UHPC in conventional concrete applications has been cost prohibitive, with commercially available/proprietary mixes costing approximately 30 times more than conventional concrete. Previous WTI research resulted in nonproprietary UHPC mixes made with materials readily available in Montana. These mixes are significantly less expensive than commercially available UHPC mixes, thus opening the door for their use in construction projects in the state. The Montana Department of Transportation (MDT) Bridge Bureau is interested in using UHPC in field-cast joints between precast concrete deck panels. The use of UHPC in this application will reduce development lengths, and subsequently reduce the requisite spacing between the decks and improve the overall performance of the bridge. Through this project, P.I. Michael Berry will build on the non-proprietary Phase I UHPC research he recently completed for MDT and focus on ensuring the successful application of this material in these field-cast joints.
If these mixes are viable for this application, Montana could take advantage of the cost savings of the non-proprietary mixes and ultimately improve the performance and durability of bridges. More information on this Phase II project is available here.
Research Scientist Marcel Huijser, of WTI’s Road Ecology program, will travel to Australia at the end of April for the 2018 Conference of the Australasian Network for Ecology and Transportation (ANET). Marcel has been invited to deliver the keynote address, entitled “Road Ecology – Are We Taking the Right Turns?” at the plenary session on the opening day of the conference.
ANET is a professional network dedicated to the research, design and implementation of environmentally-sensitive infrastructure across Australasia (Australia, New Zealand, and neighboring islands). Serving government, industry, scientists and community groups, ANET’s international conferences aim to share global best practices for identifying and mitigating the ecological impacts of all types of linear infrastructure and transport, including road, rail, pipelines and utility easements.
