New tools will help local road engineers reliably estimate the curing time of a cold in-place recycling (CIR) layer. Researchers identified factors that affect asphalt curing when a CIR method is used to know when pavement is sufficiently hardened, which will minimize delays in road construction and reopening.
Work-at-home orders during the COVID-19 pandemic resulted in drastic reductions in traffic congestion. To aid in highway planning and also inform state telework policies, MnDOT wanted to learn about telecommuting during the pandemic and future forecasts of remote work from both employers and employees of private and public organizations.

Transportation is a crucial contributor to health: It directly shapes the social and physical environments in myriad ways and determines the types of places where people can live, learn, work, and play in their everyday lives.
Climate change is exacerbating weather-related impacts on the transportation system. As floods, droughts, wildfires and other extreme weather events become more common and destructive, transportation infrastructure will need to adapt to become more resilient.

In Minnesota, trucking produces about 13 percent of the total pollutants in the state. Moreover, a 2019 EPA report identified the transportation sector as the source of the highest share of greenhouse gas emissions in the United States, a problem compounded by the fact that this pollution is more concentrated in urban areas.

Photos and stories about people biking and walking on packed trails were common during the early stages of the COVID-19 pandemic. Transportation researchers also reported surges in bicycling and walking during this time of social restrictions and widespread closures, but little was known about how those surges related to longer-term trends.

Displaying the highway death toll on message boards is a common awareness campaign, but new research from the University of Toronto and University of Minnesota indicates this tactic may actually lead to more crashes.
Over the years, dozers have been the desired tool for pushing snow drifts back along highways. While dozers work well, they are limited by the drivability between drift locations.
As the COVID-19 pandemic restrictions in 2020 kept people at home, reduced travel and, therefore, traffic congestion were to be expected. But how much of an impact did the restrictions have on traffic congestion? After analyzing changes in traffic levels due to the COVID-19 pandemic travel restrictions, researchers identified how incremental changes in vehicle miles traveled impact regional congestion. These results will inform efforts by MnDOT and its partners on the outcomes of reduced travel demand.
