Protecting Wildlife Along Minnesota Roads

This week is Wildlife Casualty Count Week of Action in Minnesota. It highlights the impacts transportation systems have on wildlife and raises awareness of wildlife deaths resulting from vehicle collisions. Information about this effort can be found at: Wildlife Casualty Count Week

At MnDOT, we are committed to protecting wildlife through established practices and thoughtful planning. MnDOT works to minimize and mitigate impacts to protected fish, wildlife, and plant species in the design and construction of transportation projects. Read more about MnDOT’s commitment to protected species here: Wildlife – Environmental Stewardship

MnDOT’s Office of Research & Innovation supports research projects that advance wildlife protection and environmental conservation. These projects help inform how wildlife considerations are incorporated into transportation planning and construction. Explore projects guiding this work below:

Solar Snow Fence Controls Drifting Snow While Generating Power

Solar snow fences not only retain the benefits of a traditional snow fence by controlling blowing and drifting snow in winter, they create green energy throughout the year. However, to be effective, the fence must withstand harsh weather elements and produce enough energy to justify the use and cost of solar panels. This project evaluated the installation and performance of a 100-foot solar snow fence for 18 months to determine its functionality and economic feasibility.

Impact of Start Time on Students Walking and Biking to School

To increase the number of students who walk or bike to school, policymakers first need to understand the primary factors that prevent students, parents and caregivers from choosing these travel modes. A look at the factors that influence this decision provided information to address barriers to walking and biking for children and families in Minnesota communities.

Increasing Service Reliability by Adding a Dedicated Right of Way for Buses

In dense urban areas, public transit is a primary mode of transportation for people to commute to work, complete errands and connect with their community. If transit is not reliable, riders may choose other forms of transportation that could negatively affect riders, transportation agencies and communities. To improve service reliability, MnDOT investigated the use of dedicated rights of way (ROWs) for transit service across route segments within the system.

Modeling and Predicting the Deterioration of Pedestrian Assets

Transportation agencies closely monitor and evaluate roads for needed repairs, but pedestrian infrastructure such as sidewalks receive less attention. When left in disrepair, this infrastructure is susceptible to deterioration and can have significant negative impacts on communities. This project collected and integrated pertinent data and developed a model that measured the deterioration of pedestrian assets to predict the effects of aging. With this additional information, agencies can better prioritize areas of need and allocate resources more effectively to maintain and repair pedestrian assets.

Examining Driver Preferences for Lane Line Patterns and Widths

Pavement markings that clearly delineate lanes are important for reducing crashes and improving the safety of drivers. The configurations of these pavement markings—primarily the width and length of the line and the spacing of broken lines—vary from state to state. This project identified driver preferences for pavement marking patterns and widths, which can increase visibility and improve safety.

New Project: Roundabouts, J-Turns, etc. – Understanding Their Economic Impacts

Roundabouts and J-turns have consistently shown significant improvements in safety and traffic flow in Minnesota and across the U.S. Still, some community residents and businesses oppose replacing traditional intersections with alternative intersections like roundabouts or J-turns.

New Project: Best Practice for Oversized/Overweight Vehicles

As hauling practices change for waste collection, mining and other industries, local transportation agencies are receiving more permit requests for oversize or overweight trucks. These larger vehicles can have significantly greater impacts on pavements than passenger vehicles.
