New Project: Assessment of Pedestrian Safety and Driver Behavior Near Automated Vehicles

With the number of automated vehicles increasing on our roadways it is important to understand their potential impacts and how other road users will interact with them. In the future, there will be a more pronounced shared levels-of-automation transportation network, with fully manual, partially automated, and fully automated vehicles sharing the same Minnesota roads. While planners and engineers have a reasonable idea of how humans drive around other humans, what is not as well-known is human driving behavior around automated vehicles.

New Project: Identifying Deer-Vehicle Collision Concentrations in Minnesota

Deer-vehicle collisions are a significant risk to public safety on Minnesota roads—causing injuries and death for humans and animals, and property damage. Minnesota ranks among the top 10 riskiest states for deer-vehicle collisions in the nation.

New Project: Designing An Autonomous Service to Cover Transit Last Mile in Low-Density Areas

Public transportation provides a safe, convenient, affordable, and eco‐friendly mobility service. However, due to its fixed routes and limited network coverage, it is sometimes difficult or impossible for passengers to walk from a transit stop to their destination. This inaccessibility problem is also known as the “transit last mile connectivity problem”.

New Project: Bridge Low Slump Concrete Overlay Mix Design for Mobile Mixers

In recent years, MnDOT has seen an increase in cracking of low slump overlays. Cracking of overlays allows chlorides to get into the bridge deck which leads to deterioration of the reinforcement and eventual delamination or spalling.  This means that the bridge deck needs to be repaired or even replaced before the service life has been reached. 

What is a low slump overlay? A low slump overlay is a technique used by DOTs to extend the life of bridge decks. They are typically 2″ thick and designed to provide low permeability.

New Project: Advancing Equity in Accessibility and Travel Experiences: The Role of Gender and Identity

In the early 1990s, Minnesota became the first state in the nation to prohibit discrimination based on a person’s sexual orientation and gender identity. Yet the state continues to use male-female categories when investigating the role of gender in transportation issues such as travel behavior and transportation accessibility. Since a person’s identity can have a significant influence on their own and others’ behavior and experiences, excluding gender diversity in this type of transportation research could result in an incomplete understanding of the issues and perceptions about quality of life.

New Project: Evaluation of Corrugated HDPE Pipes Manufactured with Recycled Content

Historically, federal regulations have required that MnDOT use pipes made with all-new materials in various applications, such as redirecting stormwater under roadways. However, recent changes to these regulations have made it possible for the agency to also consider pipes made with recycled materials, which could provide MnDOT with more options when choosing products for future projects.

New Project: Maximizing Transportation Assets by Building Community Connection Through Innovative Development of Rights of Way and Airspace

Transportation agencies throughout the United States are focused on repairing the damage that highway construction has caused in communities.

MnDOT seeks partnerships with communities, businesses, and government entities to better utilize state highway lands and airspace.

These partnerships aim to enhance economic wellbeing and quality of life. Projects like highway caps and development of spaces underneath highways can increase equity, reduce disparities, and limit environmental impacts.

New Project: Enhancing Managed Lane Equity Analysis

Managed lanes, like Minnesota’s E-ZPass express lanes, are designed to improve mobility and travel time reliability for transit users, carpoolers and other motorists during peak travel hours. The lanes provide many societal benefits such as increased transit ridership, higher vehicle occupancies, more reliable travel options, and reduced traffic congestion and pollution.

However, because the lanes use pricing to deliver these benefits, they must be designed, constructed and operated equitably. The key is striking a balance that’s fair for everyone.

New Project: Improving Transportation Equity for All by Centering the Needs of Marginalized and Underserved Communities

Government policies often prioritize the needs of the dominant group or culture, resulting in systems and services that benefit some people more than others. To better address the transportation needs of underserved communities, transportation agencies must first understand people’s lived transportation experiences. Listening is a critical first step toward mitigating the effects of marginalization and discrimination in transportation.
