Smartphone App Aims to Help Drivers Switch to More Sustainable Transportation Modes

This article was originally published in Catalyst, May 2021.

Using an innovative mobility app, U of M researchers are pointing the way for drivers to shift their travel toward more sustainable modes such as transit, park-and-ride, walking, and biking.

Earth Day 2021

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.

Improving Winter Maintenance: Pilot Testing New Snowplow Technologies

[Infographic] Testing Snowplow Technologies: Slurry Spreader (target direction of salt, reduce salt use, reduce corrosion on trucks), Two-Way Reversible Plow (located on side of plow, providing more mobility in plowing and directing snow), Underbody Scraper (located under plow, clears compacted snow and ice from roads), True-Float Wind (mounted on front or side of plow, providing more mobility in plowing and directing snow)

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).

New Project: Cost/Benefit Analysis of Fuel Efficient Speed Control Using Signal Phasing and Timing Data

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.

New Project: Have Minnesota’s Warmer Winters Increased the Number of Freeze Thaw Cycles?

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.

New Project: Taconite as a Lower Cost Alternative High Friction Surface Treatment for Low-Volume Roads in Minnesota

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.
