Detours around bridges in a critical freight transportation route create costs to the trucking industry, taxpayers and state economy. New load rating factors for the slab-span bridges across Shingle Creek will give MnDOT more flexibility in managing truck traffic and keeping freight moving efficiently.

Complete Streets is a national initiative to encourage the design of safe, convenient transportation systems with access to users of all types, ages and abilities. MnDOT’s Complete Streets policy aims to provide a safe and functional transportation system for all users. Perceived and actual economic impacts of these road projects on small cities vary, but MnDOT has new strategies to work with local partners and evaluate economic benefits for smaller communities.

Snow fences are a useful tool for controlling snow and ice on Minnesota’s roads. However, installing them relies on the cooperation of landowners. An ongoing collaboration between U of M researchers and the Minnesota Department of Transportation (MnDOT) aims to develop outreach tools that can be used to attract more landowners to the MnDOT snow fence program.

Zippy electric scooters—often called e-scooters—have quickly become a common sight on sidewalks, bike paths, and roads in most US urban areas. Americans took 38.5 million e-scooter rides in 2018 and 88.5 million rides in 2019—a 130 percent increase in a single year. However, the rapid rise of the e-scooter has come at a cost, and e-scooter injuries and crashes have become a serious public health concern.

It’s no secret that the transportation system is an uneven playing field. Understanding disparities related to race, income, and other factors is critical, and much more work is needed. Gender in particular is an under-researched yet important aspect of the design of vehicles, infrastructure, and amenities.

Fully automated vehicles may not be market-ready yet, but one day, they expect to provide a variety of benefits like reduced emissions and greater safety and transportation equity. These vehicles and the complex combination of underlying technologies that power them are continually being tested and improved to ensure the vehicles will meet the highest standards of safety and performance.

A new testing method will allow MnDOT to determine the underground foundation pile depths of high-mast light towers (HMLTs) without digging or dismantling. HMLTs need to meet design standards to ensure load-bearing stability. By using the new method to evaluate pile depth, MnDOT could avoid costly retrofits or replacements, and prioritize light towers in need of redesign.
