April 22 is Earth Day!
Climate change & the environment is one of five research strategic priorities that guide the work of Minnesota’s transportation research program.
This includes research projects specific to endangered & threatened species, wetland protections, salt use and incursion, congestion impacts on air quality, and the impacts of road construction and maintenance activity on the environment.

Every winter, MnDOT ensures Minnesotans can travel safely by plowing more than 30,000 lane miles with approximately 800 snowplows.
In a new research implementation project jointly funded by the Office of Research & Innovation and Office of Maintenance, MnDOT is pilot testing five new pieces of snowplow equipment: two slurry spreaders (one from Henke, one from Swenson), a two-way reversible plow, an underbody scraper and a true-float wing (all from Henke).

Due to rising fuel costs and environmental impact, consumers are increasingly aware of fuel efficiency (MPG) in the vehicles they purchase, which is reflected in increasing hybrid and electric vehicle sales. A major source of fuel consumption is acceleration and deceleration cycles caused by stopping at red lights—acceleration from a full stop requires significant power.

Minnesota is experiencing warmer winters and an increase in freeze-thaw events may negatively impact pavement systems. However, the impacts of these recent climate changes on freeze-thaw cycles have not been well studied.

Roundabouts reduce the severity of crashes at intersections, but transportation agencies have received some feedback from pedestrians indicating that roundabouts, especially larger multi-lane roundabouts, can be difficult to navigate.

A northern Minnesota mining byproduct could provide a more affordable option for a highly effective, but expensive pavement safety treatment called High Friction Surface Treatment (HFST), and help expand its usage across the state.
