NTC graduate student Ahmed Rageh recently had the opportunity to attend and present at the 11th University Transportation Centers Spotlight Conference: Rebuilding and Retrofitting the Transportation Infrastructure in Washington, DC. Ahmed gave a poster presentation titled, “Health Monitoring Schemes for Double-Track Steel Railway Bridges” with Dr. Daniel Linzell, UNL College of Engineering Department Chair and Professor. Ahmed is a third-year civil engineering graduate student focused on the structural health monitoring of steel railway bridges. Ahmed attended several sessions during the conference and enjoyed learning about new smart methods and tools for assessing the conditions of roadway bridges. The leading experts in attendance helped him developed a new research goal—predicting structure deficiencies before they occur. His current research involves remotely monitoring and identifying conditions of a Union Pacific double track steel railway truss bridge located in Columbus, Nebraska.
July 16 – 21, 2017
MATC recently partnered with the Nebraska Commission on Indian Affairs to build the 2017 MATC/NCIA Sovereign Native Youth STEM Leadership Academy. The academy lasted from July 16-21, and took place mostly on the University of Nebraska-Lincoln campus, where students were able to become comfortable with the layout of campus and many different opportunities held at UNL. A central objective of the academy was to help Native American youth engage their potential in leadership in STEM and transportation fields. The group of 11 native students in attendance learned from professors and professionals in STEM fields, while also visiting institutions such as the University of Nebraska Medical Center, Union Pacific, and BNSF railway to learn about potential career opportunities. On Thursday, the students were challenged to utilize critical thinking and teamwork skills to build trailers that could float in water while carrying weight. Simultaneously, the academy emphasized Native American culture and history by including an excursion to the Standing Bear trail, as well as a native experiences panel. During the six day long academy, three teachers, three mentors, and six administrative leaders including Judi gaiashkibos, Larry Rilett, Gabriel Bruguier, Chris Cornelius, Rebekka Herrera-Schlichting, and Scott Shafer interacted with the students and shared their own experiences of getting into leadership in their native communities or the STEM field.
June 12 – 15, 2017
Researchers from the Midwest Roadside Safety Facility (MwRSF), an organization under the Nebraska Transportation Center, received several paper awards at the 1st Transportation Research Board International Roadside Safety Conference in San Francisco, California. Dr. Ron Faller, Director of MwRSF, served on the planning committee and as the chair for the conference. Ron Faller, Scott Rosenbaugh, and Robert Bielenberg submitted a documentation on the configurations, special applications, and critical and unique components of 31-in. tall W-beam guardrail as well as guidance on installation. Cody Stolle, Karla Lechtenberg, Ron Faller, and graduate student Alexis Yim shared strategies for resolving one of the biggest and deadliest problems in roadside safety—trees located in close proximately to the side of the road. With the sponsorship of the Wisconsin Department of Transportation, Ron Faller, Karla Lechtenberg, Jennifer Schmidt, John Reid, Robert Bielenberg, graduate student Ana Guajardo, and Erik Emerson (Wisconsin DOT) filled an existing gap with their paper submission on the development of a crashworthy pedestrian rail design. These ongoing research projects indicate important progress toward safer, more cost-effective roadways.

On Wednesday, April 13, UNL’s Midwest Roadside Safety Facility research and test site manager Jim Holloway along with project lead engineers Scott Rosenbaugh, Jennifer Schmidt, Ronald Faller, and team performed a crash test with a 36,000-kg tractor-trailer vehicle for a group of over 50 attendees. The test was designed to evaluate the capacity and ability of Manitoba Infrastructure and Transportation’s (MIT) Narrow Single-Slope Bridge Rail to contain and redirect the heavy, tractor-trailer. The vehicle impacted the barrier at approximately 50 mph and a 15-degree angle and was successfully redirected with minimal damage to the system, meaning that the new barrier is a good candidate to replace aging barriers across Canada. In addition to MIT sponsors, this rare event drew interest from Governor Pete Ricketts; NDOR Director Kyle Schneweis and representatives Khalil Jaber, Miki Esposito, Mark Traynowicz, and Phil TenHulzen; Nebraska FHWA representatives; and law enforcement officers from Lincoln, Omaha, and the State Patrol.
