Full scale testing of modern snowplow blades can be a difficult and often unrepeatable proposition depending on the weather and where your test track is located.  In this episode Alex Klein-Paste of the Norwegian University of Science and Technology (NTNU) set about to design  scale model testing of a particular snowplow blade design in a laboratory setting.  Alex demonstrated that these tests closely mirror their full scale counterparts and set the stage for rapid development and testing of various designs.  This work was presented at the 2024 Transportation Research Board Annual Meeting in Washington, DC.

You would think that it wouldn’t be difficult to see something as big as a snowplow but during a winter storm event at night you’d be surprised how hard it is recognize a slow moving maintenance vehicle.  In this episode Jeff Pifer, Director of the Equipment Division at the West Virginia Division of Highways discusses techniques that are being used to make snowplows and other maintenance vehicles more conspicuous.  Vehicle color, lighting packages, and reflective markings and patterns are the topic of discussion.
Clear Roads has also sponsored several research projects into vehicle conspicuity and you can review this work at their website https://www.clearroads.org/equipment-plow-trucks/

Whenever you mix snowplows, winter storms, and motorists on the same stretch of pavement everyone needs to be at the top of their game in vehicles equipped for conditions.  Most of the time folks get where there headed and the roads get cleared without incident. But, there are times when vehicles get tangled up with a snow plow and the outcomes can be catastrophic. 
On this episode we’ve got Jed Falgren, State Maintenance Engineer for the Minnesota DOT who’s been involved in some really innovative projects to help reduce the number of interactions between snowplows and motorists from their CAV-Traveler Alert System to reflective materials and lighting. 
For more information on MnDOT’s efforts to reduce crashes with snowplows and other slow moving maintenance operations you can reach out directly to Jed at jed.falgren@state.mn.us

When it comes to liquid deicing products how do you know you’re getting what you paid for and that it’s likely to perform as promised?  The Nebraska DOT has been working on developing a easy to run, repeatable, and cost effective test method to determine the ice melting capacity of liquid deicing products.
Mike Mattison and Jasmine Dondlinger of the Nebraska DOT take us on the journey this test method has taken from the initial idea using a instrumented martini shaker to the Rocker AASHTO Provisional Test Method and why this test method should be part of your winter operations program when it comes to liquid deicing products.

If you would like more information about the new Rocker Test Method or how it might fit into your winter maintenance program you can contact Mike Mattison at mailto:Mike.Mattison@nebraska.gov or Jasmine Dondlinger at mailto:Jasmine.Dondlinger@nebraska.gov .

There’s lots of discussion going on these days regarding artificial intelligence or AI.  Like it or not you’re probably using or at least taking advantage of AI applications right now and you might not even know it.  Winter operations takes place in an environment well suited for AI applications to provide assistance across a broad spectrum of activities from road weather forecasting to decision support to operator assistance in the cab through lane guidance, material applications, and a host of other potential applications.  
In this episode Software Engineer Tom Brummet with the National Center for Atmospheric Research, Research Applications Laboratory discusses AI and ongoing work in winter maintenance and road weather.
If this episode peaked your interest in Artificial Intelligence applications in winter maintenance you can check out what’s happening at the National Center for Atmospheric Research, Research Applications Laboratory at this link https://ral.ucar.edu/technologies/artificial-intelligence-and-machine-learning or you can email Tom Brummet directly at brummet@ucar.edu.

Public works agencies have struggled for years recruiting and retaining a skilled workforce. These challenges have reached critical levels for many agencies since the pandemic. In this episode were Talkin’ Winter Ops with the City of Columbus Department of Public Service Human Resource Officer Lauren Hunter and Infrastructure Operations Coordinator Scott Lucas about a recruiting program that takes them into the Ohio Reformatory for Women in Marysville, Ohio and a unique vocational program partnership offering 2nd chances with the City of Columbus.
For more information of this program email Lauren Hunter at lbhunter@columbus.gov or Scott Lucas at selucas@columbus.gov
