Twenty years ago in 2004 “Where The Weather Meets The Road” was published by the National Academy of Science and it proposed a research roadmap over the next 20-years to advance road weather services. Now in 2024 the future described in Where The Weather Meets The Road is here Paul Pisano, Chair of the TRB Road Weather Committee and Dr. Gina Eosco, Division Chief, Science, Technology, and Society for the Weather Program Office at the National Oceanic and Atmospheric Administration were ...

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 ...

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 patter...

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 rea...

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...

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, ...
