New Project: Understanding How the Disparate Effects of COVID-19 are Affecting MnDOT’s Efforts at Equitable Contracting

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.

New Project: COVID-19 Impacts on Speed and Safety for Rural Roads and Work Zones

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.

Improving Winter Road Weather Alerts on Highway Dynamic Message Signs

MnDOT maintains nearly 400 dynamic message signs (DMS) along Minnesota highways that display real-time information to warn motorists of roadway incidents, construction or congestion ahead that could pose a hazard or cause delay. DMS use to convey weather alerts has been limited to blizzards and other very isolated winter conditions. MnDOT has been concerned about the timeliness of weather messages and the chance that such messages could be overused, possibly leading motorists to take them less seriously.
