(3/8/2020) - Minnesota Toward Zero Deaths has awarded its annual Engineering Star Award to Renae Kuehl, LRRB research implementation and outreach consultant, in recognition of her work on safety-related initiatives such as the Statewide County Road Safety Plans, which draw on the findings of LRRB research. “These efforts make Renae a key person involved in reducing the number of traffic-related fatalities on Minnesota's roads,” the awards committee stated.
(3/8/2020) - Researchers have further refined a quick and innovative pothole repair method using taconite mixtures. The recently completed study was funded by the Minnesota Local Road Research Board in collaboration with MnDOT, the City of Duluth, and the Duluth International Airport. Researchers evaluated the performance of taconite repairs completed in 2018-2019 and developed a new two-ingredient mixture. The mixture shows promise as a cost-competitive, long-term solution for potholes. For more information, visit the research project page.
(3/4/2020) - Using a sophisticated driving simulator, LRRB-sponsored researchers determined that 400 and 600 feet of sight distance is insufficient at rural intersections. Drivers performed much better with 1,000 feet of sight distance, both at intersections and on main line roads responding to vehicles running stop signs. Researchers also noted that moving the stop bar closer to the main line at thru-stops would both increase the sight distance of waiting drivers and influence the main line drivers to slow down when approaching intersections. Safety could be increased with this very low-cost change. For more information, visit the research project page.
