Study recommends biodiversity when planting roadside vegetation

April 24, 2023

Traditional practices for planting and maintaining roadside turfgrass in Minnesota have generally focused on finding a few plant species that do well in combination and blanket-prescribing them across the state. A recent U of M study, however, finds that plantings tend to do better when they are both biodiverse and carefully matched to their ideal growing conditions.

COVID’s Effects on Public Transportation Use and Perceptions

How has the pandemic affected downtown commuters’ travel behavior and perceptions of public transportation?

The COVID-19 pandemic has taken a major toll on public transit ridership—raising questions for the future. Will people associate public transportation with health and safety risks and avoid using it? Will they see public transportation as a less desirable transportation alternative?

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.

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.
