MnDOT designs stormwater management infrastructure based on historical rainfall data and traditional design assumptions, including rainfall intensity and distribution, rainfall event duration and existing moisture conditions. Stormwater management infrastructure designed using traditional design parameters determines the risk of flooding, property damage and human safety in communities.

New Project: Roadside Feature Placement and Pedestrian Safety on Low and Intermediate Speed Roads
Guidelines for designing and placing roadside features have traditionally focused on automobile safety on higher-speed roads. Research has also shown feature placement can have safety benefits for pedestrians and bicyclists on lower-speed roads.

Testing High Friction Aggregates using SCRIM Technology at MnROAD
High Friction Surface Treatments (HFST) are pavement treatments that involve applying a high-quality aggregate and binder to pavement surfaces to help maintain friction. The treatment has significantly reduced crashes and injuries in wet and dry road conditions in high crash areas. However, HFST can be a costly treatment. Researchers, funded by MnDOT and the Local Road Research Board, are evaluating if taconite, a readily available Minnesota byproduct, can be an effective alternative treatment in low volume areas.

New Project: Cost Benefit Analysis for Sustainable Energy Building Upgrades at Safety Rest Areas and Travel Information Centers
MnDOT manages over 50 large safety rest areas (SRAs) with several amenities and travel information centers (TICs) with expanded customer service. Many of the SRA and TIC buildings were built before the significant advancements in energy efficiency and building technology made in the past few decades.

New Project: Vulnerability Assessments of Critical Slope Areas Using Advanced Monitoring Techniques
MnDOT continues working on systematically and proactively assessing stability of slopes along its highway system. Efforts are aimed at minimizing the potential for slope failures that could result in threats to public safety and costly repairs.

New Project: Use of MNCORS to Support AV Operations in Rural Minnesota
Autonomous vehicles (AVs) have infrastructure requirements such as lane lines, centerlines and intersection signs to guide camera-enabled steering control functions. But many rural roads do not have lane markings or are unpaved, and intersections might be missing components to guide AVs.

Introducing a New Red-Light Running Warning System that Can Potentially Reduce Human Errors at Intersections
Red light violations remain a prominent issue and high contributor to serious crashes and casualties at signalized intersections. An ongoing research project, funded by the Local Road Research Board, and Federal Highway Administration (FHWA) State Transportation Innovation Council (STIC) Incentive program, is developing and testing a warning system that signals drivers as they approach a red light and prompts them to decelerate.

New Project: Comparative Analysis of Grade-Separated Pedestrian Infrastructure and At-grade Treatments
Grade-separated intersection crossings allow pedestrians to cross over or under traffic lanes. Several factors determine whether a specific location is appropriate for a grade-separated crossing, such as volumes of vehicle and pedestrian traffic, number of lanes to cross, and vehicle speed and visibility.

New Project: Long-Term Field Performance Evaluation of Chip Seals
Chip seals are an economical road surface treatment that MnDOT and counties use to enhance existing pavement performance and service life. A thin layer of asphalt emulsion sprayed on the pavement surface and mixed with aggregate chips can address minor pavement distresses and seal the pavement surface to reduce the impacts of further wear.

New Project: Species from Feces: A New Tool to Identify Bats in Culverts and on Bridges
Three bat species in Minnesota have been decimated due to white-nose syndrome. The northern long-eared bat is listed as endangered by the U.S. Fish and Wildlife Service, the tricolored bat listing is imminent, and the little brown bat listing is under consideration.
