Guidance to Help Local Agencies Address Deferred Maintenance

Local government budgets are continually inadequate to meet increasing transportation maintenance needs. In a recent study, researchers analyzed maintenance investment decision-making in local governments across Minnesota, identifying the fiscal conditions that impact road repair spending, recommending steps to close maintenance funding gaps and providing context to inform communications with decision-makers.

EV System Impacts

Model helps analyze EV system impacts, evaluate policies for subsidies and charging

Electric vehicles (EVs) are expected to capture a substantial portion of the future vehicle market. In the short term, however, technology and infrastructure limitations—such as driving range and charging availability—will prevent transition on a large scale. Because EVs will share the road network with gasoline vehicles (GVs), says Alireza Khani, “it’s crucial to understand how EVs and GVs will coexist.”

Are we ready for CAVs?

Thousand-mile trek collects data on Minnesota’s readiness for automated vehicles

How ready is Minnesota for connected and automated vehicles (CAVs)? Last August, researchers took a four-day, 1,086-mile trip around the state to find out. A newly published report details the team’s findings for transportation professionals and agencies as they consider how to make improvements to our transportation infrastructure for automated vehicles and driving.

Commodity Flow Data for Freight Network Infrastructure Planning

Minnesota’s economy depends on efficient freight movement across the state. To ensure that infrastructure can accommodate cargo transport by all modes, MnDOT needs commodity flow data to plan improvements and minimize supply chain disruptions. An analysis of existing resources and needs will support new tools to optimize investments in freight transport.

Comparing Additives Used in Stabilized Full-Depth Reclamation

Beltrami and Hubbard counties planned pavement rehabilitation on a shared road, presenting a unique opportunity to directly compare two stabilizers: engineered emulsion and Base One, a proprietary mix. While there were some variations in performance and cost, both met design values for pavement strength.

CTS Symposium Speakers Offered Ideas for Building Supply Chain Resilience

Article originally published in Catalyst, February 6, 2023.

Supply chains aren’t normally at the top of the news, but pandemic-related disruptions and empty shelves have put them there. What does the future hold for freight and supply chain resilience? Speakers at the 25th Annual Freight and Logistics Symposium reviewed recent challenges and discussed how to make supply chains more cooperative, connected, and resilient.

Exploring Region-Specific Roadside Turfgrass Varieties

Local agencies need cost-effective and durable turfgrass seed mixes to ensure grass coverage remains optimal along roadsides. In a recent study, researchers analyzed the performance of grass seed mixtures and planting costs, recommended region-specific mixes and developed a cost estimation tool for local agencies to be confident in their roadside vegetation choices.

Study of Alcohol Overservice Finds Lack of Enforcement

Originally published as Study of alcohol overservice finds a lack of enforcement—and opportunities to improve in Catalyst, February 2023.

Overservice—the act of serving alcohol to an obviously intoxicated person—contributes to motor vehicle crashes and violence, and it’s illegal in 48 out of 50 states. Still, U of M researchers say overservice tends to be understudied and underenforced.

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.
