Transportation is the number one emitter of greenhouse gas emissions in Minnesota and medium to heavy duty trucks contribute to about 40% of transportation carbon pollution.
While electric cars and buses are becoming more common, medium and heavy duty electric trucks are still in their infancy, and the nationwide infrastructure needs to support them still has to be determined.
In a new study, MnDOT will identify the electric charging infrastructure needed along Minnesota highway corridors to support clean freight transportation.

MnDOT’s Disadvantaged Business Enterprise (DBE) Program was established by the federal government to ensure women-owned and minority-owned businesses have the opportunity to participate in MnDOT contracts.
Several contracting barriers exist for DBEs, which may have been exacerbated by COVID-19, such as access to capital, a shortage of PPE materials and staffing shortfalls due to workplace risks and caregiving responsibilities.

In response to the COVID-19 pandemic, many employees in both the public and private sectors have begun telecommuting. The resulting reduction in commuting hours and miles traveled on state highways has been staggering.

Although Minnesotans drove significantly less in 2020 due to the COVID-19 pandemic, there was a substantial increase in fatal motor vehicle crashes. MnDOT Traffic Safety Engineer Derek Leuer and his colleagues want to know why, particularly in rural areas where fatalities and injury rates were higher.

As Minnesota worked to slow the transmission of COVID-19 in 2020, travel on MnDOT roadways dropped sharply and carried with it a corresponding drop in congestion.

Expenditures for maintenance are not keeping pace with the needs of the local transportation system. When local governments face fiscal stress, planned maintenance gets postponed to make funding available for other purposes. As deferred maintenance grows, the work and investments needed to bring an asset into a good condition grow too.

Climate change scenarios have been fairly well-tested and vetted. Moore et al. (2015) found that one of the noteworthy impacts on upper Midwest cities is an increase of storm magnitude of 39% (moderate scenario) to 163% (pessimistic scenario). However, the impact of these scenarios on stormwater infrastructure are not well understood and documented. There are some important financial decisions that need to be made for stormwater infrastructure in the present and near-future, requiring demonstration and discussion of the impacts of climate change on stormwater infrastructure.

Complete Streets is a transportation policy and design approach that requires streets to be planned, designed, operated, and maintained to enable safe, convenient, and comfortable travel and access for users of all ages and abilities regardless of their mode of transportation.

Rural intersections account for 30% of crashes in rural areas and 6% of all fatal crashes, representing a significant but poorly understood safety problem.
Transverse rumble strips are one low-cost measure that some states have deployed to reduce rural intersection crashes.
