While fully automated vehicles (AVs) have not yet reached the roads, the work to get them market-ready is steadily moving forward. One of the essential technologies these vehicles rely on for safety and performance is lidar, which has traditionally experienced a loss of accuracy in bad weather.

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.

Continue reading COVID’s Effects on Public Transportation Use and PerceptionsElectric 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.”

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.
