New Technology and Existing Equipment Improve Statewide Vehicle Classification Counting Process
In a recent study, researchers leveraged previous MnDOT research and existing traffic monitoring infrastructure to refine inductive loop signature technology that counts and classifies vehicles. Positive results have given MnDOT a feasible and cost-effective way to collect vehicle classification data throughout the state for planning and decision-making.

Assessing Culvert Designs for Aquatic Wildlife Capabilities and Future Resiliency
Culverts that influence the speed, depth or flow of a natural waterway can have a detrimental impact on fish populations. By assessing sites across the state, MnDOT sought to identify the effects the culverts have on aquatic wildlife currently and project what potential flooding and drought scenarios could mean in the future.

Quantifying the Benefits of Improved Compaction
Compaction is the final and most critical step in asphalt pavement construction. National research conducted several years ago indicated that a slightly more compact pavement than typical could help roads last longer. To understand the relationship between pavement density and long-term performance, MnDOT has built a database with performance data from samples collected soon after they were constructed more than a decade ago. The agency hopes to eventually have enough data to determine the right amount of compaction.

Innovative Additions Could Help Asphalt Pavements Sense Damage—and Repair Themselves
This article was originally published in Catalyst, January 2022.
University researchers are investigating ways to extend the life of asphalt pavements and generate cost savings by adding innovative materials to asphalt mixes. In a recent study, they found that improving asphalt mixes with graphite nanoplatelets and taconite concentrates offers new possibilities for enhancing damage-detection techniques and restoring subsurface cracking using microwave energy.

Model Helps Predict Likelihood of Farm Vehicle Crashes on Public Roads
This article was originally published in Catalyst, January 2022.
A U of M study of farm vehicle safety on rural roads identified factors—such as crop type and number of vehicles operated—that can help predict the likelihood of a farm’s vehicles being involved in a crash on a public road.
