New Project: Assessing Effectiveness of Pond Sediment Removal for Phosphorus Management in Stormwater Ponds
MnDOT manages rainwater runoff to keep pollutants like phosphorus from Minnesota’s lakes and streams. Stormwater retention ponds, an established management strategy, allow phosphorus to settle to the pond’s bottom but do require periodic cleanout.

Improving Traffic Signal Visibility
Inconspicuous traffic signals are often cited as contributing to collisions at intersections. If that is true, making traffic signals more conspicuous should lead to fewer crashes. A study published at the TRB conference in 2005 suggested that yellow retroreflective backplates were most effective, reducing accidents by 15% at intersections, and the FHWA later adopted this as a Proven Safety Countermeasure.

New Project: Investigating Real Storms and the Impact of Potential Climate Change Adaptations
MnDOT designs stormwater management infrastructure based on historical rainfall data and traditional design assumptions, including rainfall intensity and distribution, rainfall event duration and existing moisture conditions. Stormwater management infrastructure designed using traditional design parameters determines the risk of flooding, property damage and human safety in communities.

Tribal Pedestrian Safety
A new video developed by the Center for Transportation Studies highlights a multiyear study of pedestrian safety at reservations that was undertaken by U of M researchers and partners from seven Anishinaabe tribes. The work was sponsored by the Minnesota Department of Transportation (MnDOT).

Best Practices for Protecting Equipment from Chemical Deicer Corrosion
Reprinted from Clear Roads News, October 2, 2024
In 2015, Clear Roads project 13-04 published a Manual of Best Practices to compile the various products agencies use as well as guidance for preventing corrosion on highway maintenance equipment.

Identifying Risk Factors for Deer-Vehicle Collisions
Deer-vehicle collisions are a significant safety hazard on Minnesota roads. While MnDOT strives to employ safety measures on roads at high risk for these collisions, identifying these areas can be challenging. Numerous variables impact where deer are more likely to be present near roads, and many collisions go unreported. A new tool estimates the risk levels—based on road type, geographical features, deer population and other characteristics—for each road segment in the state. In addition, a new method of estimating reporting rates will help MnDOT understand the extent of deer-vehicle collisions in a specific area.

New Project: Cost Benefit Analysis for Sustainable Energy Building Upgrades at Safety Rest Areas and Travel Information Centers
MnDOT manages over 50 large safety rest areas (SRAs) with several amenities and travel information centers (TICs) with expanded customer service. Many of the SRA and TIC buildings were built before the significant advancements in energy efficiency and building technology made in the past few decades.

TZD Traffic Safety Hotdish: A Roadmap for Traffic Safety Culture Research and the Road Ahead
Wednesday, July 17, 2024
10:00 – 11:15 a.m. CDT
As states and localities adopt a vision of zero traffic fatalities, greater attention must be given to communication, collaboration, leveraging resources, and applying a systemic approach to traffic safety which requires a change in culture among road users and traffic safety agencies. This change in culture is tied to education, engineering, enforcement, and emergency services.
This free virtual event will highlight the Traffic Safety Culture Research Roadmap, recently released by the National Academies of Sciences, Engineering, and Medicine. The roadmap (Research Report 1091) presents a path forward to promote traffic safety culture among state departments of transportation and other transportation safety agencies.
Dr. Wes Kumfer, who led the creation of the roadmap, will review its development and contents. Jay Otto will share example projects and show how they fit into research on traffic safety culture. Join us to learn how you can identify traffic safety culture research needs and get insights to take back to your own organizational cultures!
The webinar is free to attend, but registration is required. Once you have registered, you will receive an email confirmation with a Zoom link. The link should not be shared with others; it is unique to you.
