CTS Webinar: EV Infrastructure and Fuel Policy—Understanding the Transportation and Economic Impacts

Thursday, April 23, 2026, 2:00–3:30 pm, Virtual

About the Webinar

Transportation policy and energy markets are evolving rapidly as states explore strategies to reduce emissions and support new fuel technologies. This webinar will examine two current policy areas shaping transportation systems: electric vehicle infrastructure development and low-carbon fuel standards.

Beth Kallestad from MnDOT’s Office of Sustainability and Public Health will provide an overview of Minnesota’s Electric Vehicle Infrastructure Program. Her presentation will discuss how the Infrastructure Investment and Jobs Act and NEVI funding have shaped the development of EV infrastructure in Minnesota, the program’s current status, and what to expect in the next phase of implementation.

Monica Haynes and Neil Wilmot from the University of Minnesota Duluth will highlight a 2025 study that examined the relationship between low-carbon fuel standard (LCFS) programs and gasoline prices. They will explore how LCFS programs in other states have affected retail fuel costs and discuss the challenges of predicting the economic impacts of a potential LCFS program in Minnesota.

Through these presentations, webinar attendees will gain insights into how emerging transportation energy policies influence infrastructure planning and economic outcomes.

CTS Webinar: Species from Feces—A New Tool to Identify Bats in Culverts and on Bridges

Wednesday, April 22, 2026, 12:00–1:30 pm, Virtual

About the Webinar

Bats frequently use bridges and culverts as roosting habitat, creating challenges for transportation agencies working to balance infrastructure needs with environmental compliance. Traditional visual surveys can be limited, especially when bats are hidden within structures or present only intermittently. 

This webinar will highlight ongoing research exploring the use of DNA analysis from bat feces (guano) as a noninvasive method to identify bat species occupying culverts and bridges. Speaker Ron Moen will discuss how this approach works, share early findings from field applications, and explore how the results could support more efficient environmental review, project planning, and species protection efforts for transportation agencies.

It is being held in conjunction with a CTS Environment and Energy in Transportation Council meeting.

Speaker

Ron Moen is an associate professor in the Department of Biology at the University of Minnesota Duluth and a senior research associate with the Natural Resources Research Institute’s Center for Water and the Environment. His research focuses on mammalian ecology, including habitat use, movement patterns, and predator–prey interactions, often using GPS radiotelemetry. His current work includes studies on moose, Canada lynx, American marten, wood turtles, bats, and other wildlife, as well as projects related to climate change impacts and carnivore monitoring in the Upper Midwest.

New Project: Engineering Post-Construction Soil Composition to Support Resilient Stormwater Management

Post-construction soils can produce much higher stormwater runoff rates than pre-construction or typical vegetated soils. Poor soil conditions can hinder the establishment of vegetation and carry large volumes of runoff, sediment, and nutrient loads to local waters. Organic soil amendments (composts) may support post-construction vegetative growth by boosting soil structure, nutrient availability, and water holding capacity.

This research aims to define targeted pre-construction soil health baselines, determine optimized design and field implementation inputs that return soils to baseline health indices using organic amendments, and identify how these inputs can benefit transportation requirements and resilient stormwater treatment.

The results may facilitate the quantification of benefits provided through soil health restoration and the development of implementable guidance for roadside soil health restoration techniques.

“This research project will help us understand how implementing soil health practices can improve the performance of roadside vegetation establishment resulting in MnDOT being able to close out construction contracts and stormwater permits sooner,” said Warren Tuel, Natural Resources Program Coordinator with MnDOT’s Office of Environmental Stewardship. “There are also significant potential stormwater benefits of soil health practices including increased infiltration, improved treatment of pollutants present in highway stormwater runoff. The improved management of stormwater will result in improved water quality of runoff from MnDOT highway systems resulting in greater protection of the many water resources here in Minnesota.”

The objectives are:

  1. Evaluate resilience to water availability through organic amendment (e.g., compost) addition through greenhouse stormwater experiments
  2. Optimize amendment loadings based on resilience
  3. Develop a “recipe” for improving the health of poor soils based on soil health measurements, by amending the soil with compost or other organics

Project Details

  • Start Date: 05/16/2025
  • Estimated Completion Date: 06/30/2027
  • Funding: MnDOT
  • Principal Investigator: Bora Cetin
  • Co-Principal Investigators: Angela Farina
  • Technical Liaison: Warren Tuel

Comparing Salt Brine and Granular Salt for Safety and Performance

While studies have shown that salt brine can be less expensive and better for the environment than granular salt, public perception maintains that salt brine is less efficient and less safe for travelers.

In this Clear Roads project, researchers developed metrics for comparing the two different forms of salt and conducted a variety of tests to measure their performance in the field.

Now, agencies have data and infographics they can use to support their decision to use salt brine in place of granular salt.

Pedestrian Safety Impacts of Dedicated Right-Turn Lanes

While research has found that right-turn-only, or dedicated right-turn lanes, at intersections reduce traffic delays and vehicle crashes, their impact on pedestrian safety has been unclear. To better understand these impacts for future intersection design and countermeasure considerations, this project investigated driver response to pedestrians in or near crosswalks at dedicated right-turn lanes.

The winding road to an electric fleet

Reprinted from CTS News, November 24, 2025

Even for cities, counties, and organizations with zero-carbon emissions goals, most fleet managers are skeptical about going fully electric. Calculating the return on investment for a single vehicle is straightforward—but for a fleet, it’s complex.

CTS Webinar: Preparing Transportation Professionals for AI Integration

Monday, December 15, 2025, 12:00–1:30 pm (Virtual)

About the Event

Artificial intelligence (AI) is rapidly reshaping how we design, plan, and manage infrastructure systems. In this webinar, CTS scholars Qizhi He and Seongjin Choi from the University of Minnesota’s Department of Civil, Environmental, and Geo- Engineering will discuss how AI tools are beginning to influence teaching, research, and professional practice in civil engineering. Their conversation will consider how the field can adapt curriculum and training to prepare future engineers for an AI-integrated profession. They will also explore questions around quality management, professional ethics, and community-centered design in an AI-driven context.

Offering a practitioner’s perspective, Melissa Barnes will share insights from MnDOT’s ongoing AI pilot identification project. She will discuss how state agencies are evaluating opportunities and risks associated with AI implementation—and engaging and educating their staff about AI.

This webinar will highlight opportunities for collaboration between academia and practice as the transportation industry navigates the evolving impacts of AI on engineering education, quality assurance, and workforce development.
