In a project funded by MNDOT, entomologists developed an innovative method for surveying bumble bee populations alongside roadways. The researchers have recently published an article in Biological Conversations, Vol 283 focusing on the lessons learned about sampling when surveying these quick-moving bees.

Understanding Transit and Shared Mobility Preferences in Greater Minnesota Post-COVID
Public transit and shared mobility use sharply decreased during the pandemic. To remain viable, transit agencies and other transportation services in Greater Minnesota need to recover customers. A recent project identified rider preferences, safety measures and service improvements to increase interest in and use of alternative transportation.

New Clear Roads Research: Evaluating high-performance plow blades
A variety of factors can affect a snowplow blade’s long-term performance, making it difficult for an agency to determine which blades are the most cost-effective overall. By developing a field test protocol and cost-benefit analysis methodology, the new research will make it easier for Clear Roads agencies to evaluate and compare blades in the future using the same standard procedures used in this project.

New Project: Evaluation of Gravel Stabilizer Used on Gravel Roads and Shoulders
Approximately 50% of roads in Minnesota are gravel. The performance and long-term sustainability of such roads depend on the quality of the surface layer. Unbound large particles can form an unstable road surface that becomes rough, developing potholes and corrugations as this material is scattered by vehicles or washed away by rain. As a result, more frequent maintenance and reconstruction is required, which becomes very expensive for Minnesota counties.

New methods to determine safe bridge loading will help keep Minnesota’s truck freight moving
April 10, 2023
When transportation officials determine which route a heavy truck should take, their aim is maximizing efficiency while ensuring safety. Detours around bridges on critical freight routes increase fuel and labor costs for the trucking industry—and eventually hit consumer pocketbooks, too.

Findings Lay Groundwork for Shared Mobility Transit in Rural Minnesota
Originally published in Catalyst, February 13, 2023.
Public transit services are vital for community health and connectivity, yet the transit solutions found in urban areas—such as frequent bus service and light rail—don’t exist in rural areas. As a result, mobility may be limited in rural communities because of the high costs and low availability of affordable, reliable transportation options.
