Understanding Pedestrian Travel Behavior & Safety in Rural Settings

The purpose of this research is to improve our understanding of walking behavior and safety in rural MN communities by building upon MnDOT's success in creating a program to count people walking and biking. In particular, four tribal nations (Bois Forte, Fond du Lac, Mille Lacs, and Grand Portage) are collaborating with researchers at the University of Minnesota, as well as MnDOT district engineers and planners to: ...more »

Using Technology to Accurately Count Airport Operations

Many technologies have been deployed to attempt to count the number of aircraft operations at General Aviation airports. Among these are acoustic counters, radio monitors, pneumatic tube, game trail cameras, and manual counts. Each of these technologies has limitations that do not allow truly accurate accounting of airport operations at reasonable cost. This project would develop technology to deploy video cameras ...more »

Use of innovative technology to deter bat-bridge use

Minnesota is home to eight species of bat. Four of Minnesota’s bat species migrate south during the winter months, while the other four bat species (“cave bats”) overwinter locally in natural caves and man-made structures such as mines, sewers, and buildings. Cave bats in Minnesota and elsewhere are threatened by a relatively new fungal disease known as white-nose syndrome (WNS), which has resulted in cave bat population ...more »

Training Module for the Tailgate Test for Determining Appropriate Sediment-reducing Chemicals/Dosage

A training module for construction site field personnel is needed for a recently-completed project that developed a practical sediment control method for fine silt/clay sediment that is especially difficult to manage in runoff from construction sites. The Tailgate Test Kit quickly and easily identifies flocculants that reduce turbidity in construction stormwater discharge. The mobile test setup efficiently determines ...more »

Highway Renewable Energy: Harnessing the Suns Energy through Noise Barriers and Structural Snow Fencing

Explore the use of new materials and construction methods for Noise Barriers and Structural Snow Fencing that harnesses the suns energy by creating renewable energy to offset the cost of constructing and maintaining noise barriers and structural snow fencing. Currently Noise Barriers and Structural Snow Fencing each serve their intended purpose of reducing noise and blowing snow but tend to be one dimensional. Through ...more »

Environmental Field Evaluation of Potassium Acetate

Salts, primarily sodium chloride have been used as a winter snow and ice control chemical for over 50 years in Minnesota. MnDOT alone used 197,417 tons of salt during the 2016-17 winter season, along with widespread use by local governments and private applicators. Due to corrosion issues and environmental impacts to soil and water quality, alternatives to chloride based chemicals have been explored and utilized. Potassium ...more »

Modify MPCA Permit Process – Current focus is point/site; make it more applicable to linear corridors.

This potential research could: • Survey local governments to identify their NPDES experience and develop a list of issues/case studies. This survey will also help to determine if this is a systematic issue or localized. (There is speculation that the issue may be dependent on the openness/flexibility of MPCA representatives.) • Document the issues, concerns and potential changes to the permitting process. • Facilitate ...more »

Bridge and Structures

Steel Reinforcement Section Loss Guidance Tables

MnDOT has seen substructures with concrete cover spalling and delamination from aging infrastructure exposed to deicing salts and leaking joints. Many of these bridges were built under design specifications that would not meet current reinforcement detailing and reinforcement area calculations. When bridge repairs are scheduled, it is unknown the level of reinforcement section loss should be assumed. Actual reinforcement ...more »

Re-tightening the Large Anchor Bolts of Support Structures for Signs and Luminaires: Phase II

Currently MnDOT is experiencing problems with loose nuts at the anchor bolts of various transportation structures including signs and luminaires. To address this issue, MnDOT funded a research project titled “Re-tightening the Large Anchor Bolts of Support Structures for Signs and Luminaires,” which will end in June 2018. In this project, the researchers developed guidelines with tables and charts for tightening and re-tightening ...more »

Maintenance Operations

Implementation of Wet or Soft Soil Crossing Technology

Maintenance and construction operations need to cross and stage over wetlands or low bearing capacity soils to perform necessary state work. Various permits require wetland avoidance or minimization of impacts. Additional environmental commitments include minimizing or preventing soil compaction, preservation of soil function and structure, preservation of the native plant community, preservation of soil habitat for ground ...more »

Winter Maintenance - Plow routing optimization

This research will include a synthesis on existing national research while providing data to address the following questions: • What is the best approach to optimize plow routing? • Is plowing long straight routes more productive than routes that only require right turns? • Is there data supporting routing smaller geographic areas? • What are the best strategies to collaborate with adjacent agencies to share plowing ...more »
