Episode 23: Is the wind blowing in Wyoming? High wind blow-over hazard warnings.

By Podcasts No Comments

One of the benefits of the Connected Vehicle Pilot Project is the ability to generate weather alerts including high wind blow over hazard warnings. This system is proving to be most helpful to commercial traffic along Interstate 80 through Wyoming. During last years Transportation Research Board Annual Meeting Rhonda Young made a presentation on this topic The material she shared is being revisited in this podcast.

In the 2nd State Showcase webinar Joe Thompson, New York State DOT Snow and Ice Program Manager and Todd Cook, South Carolina DOT District Maintenance Engineer present their use of technology in addressing the challenges of winter maintenance in their home states.  For more information about their presentations you can email them directly by clicking on their names above.

Episode 22: EDC5 – Weather Responsive Management Strategies

By Podcasts No Comments

Weather Responsive Management Strategies is one of the rapid deployment initiatives that is part of the FHWA program Every Day Counts.  Every Day Counts is a program that helps states rapidly deploy proven but underutilized technologies. 

When it comes to managing the transportation system during adverse weather events there are three actors involved in making this a success. The maintenance operators who are performing the winter maintenance operations of plowing and applying chemicals to remove the snow and ice from the roads, the network operators who staff the traffic management centers and insure motorists have the most up to date information about the transportation network, and the motorists who actions or inactions can keep the network operating smoothly or tie it in knots.

Every Day Counts #5 – Weather Responsive Management Strategies is designed to demonstrate how road management strategies driven by data from the road users themselves can help keep the system operating smoothly.

Episode 21: Snow fence is a SAFE bet in blowing snow

By Podcasts No Comments

Controlling drifting snow has been a winter maintenance challenge for as long as there has been the desire to have mobility.  Departments of transportation have using these structures for many years to help keep blowing snow from the roadway.  One way to look at the effectiveness is how well they keep snow off the road and another is to see what positive benefit there is for the driver.  

On this episode we’re talking with Graduate Student Rachael Larson and Dr. Mohamed Ahmed of the University of Wyoming about a presentation made at the Transportation Research Board Annual Meeting on recently completed work looking at the safety effectiveness of snow fences in Wyoming based on vehicle crashes.  You can view this paper “19-05707 Quantifying the Safety Effectiveness of Snow Fence Implementations Based on Crash Severity and Snow Fence Type Utilizing Contemporary Statistical Analysis Methods” at the TRB Annual Meeting Online 2019 website at


Episode 20: TSMO365 – Weather or not

By Podcasts No Comments

Keeping the public moving in all weather conditions is an orchestrated dance between the maintenance forces, the network operators, and the public.  The actions of one influences the reactions of the others.  Road weather management strategies are employed by both the maintenance forces and the network operators independently or in unison to help mitigate the mobility challenges for the motorists to maintain a safe, reliable transportation system.  This is what we call Transportation System Management Operations every day of the year, rain or shine, or TSMO365.

SICOP talks Winter Ops with Steve Cook of the Michigan Department of Transportation, Chairman of the Community of Practice on Road Weather Management and member of the Committee on Transportation System Operations, Committee on Maintenance, and the SICOP Steering Committee.

Webinar: Showcasing the use of technology in achieving the maintenance mission

By Webinars No Comments

Observing the approach our colleagues take in addressing a particular situation is the purest form of grass-roots technology transfer.  Even if your particular situation doesn’t exactly match theirs, their approach might just provide that nugget of insight or spark of creativity that can lead you to a solution to meet your particular needs.

SICOP Talks Winter Ops hosted this webinar in cooperation with the AASHTO Committee on Maintenance, Maintenance Operations Technical Working Group showcasing how two states approached unique situations facing their maintenance operations as a result of weather events.

Brad Darr, State Maintenance Engineer for the North Dakota DOT, discussed how the closing of 8 maintenance garages in 2017 resulted in a legislatively mandated Garage / Route Optimization Study.  The North Dakota DOT utilized off the shelf  route optimization techniques to answer difficult questions associated with winter maintenance operations.  Brad’s presentation can be viewed by clicking ND DOT Section Optimization Project.

Emily McGraw, State Maintenance Engineer for the North Carolina DOT discussed how the response, recovery, and reimbursement lessons learned from Hurricane Matthew in 2016 were applied Hurricane Florence came calling in 2018. Emily’s presentation can be viewed by clicking NCDOT Weathering the Storms Matthew to Florence.


Episode 19: When the snow hits the fan – Emergency operations methodology

By Podcasts No Comments

Maintenance is used to responding to severe weather but when the storm escalates into a state of emergency maintenance becomes just one of the players addressing the event.  Clear Roads commissioned a project – Emergency Operations Methodology for Extreme Winter Storm Events.  SICOP Talks Winter Ops with the Principle Investigator, Jim Sullivan from the University of Vermont – Transportation Research Center and the best practices he uncovered during this project.

Episode 18: Just what has SICOP been up to? 2018 SICOP Year In Review

By Podcasts

SICOP exists to support member states in fulfilling their winter maintenance mission.  As one of AASHTOs Technical Service Programs we are supported through voluntary contributions made by state DOTs.  Throughout the year SICOP performs many different activities in this cause.  In this episode, SICOP Steering Committee Chair Steve Lund from the Minnesota DOT talks about the accomplishments of the program in 2018.   You can see the  2018 Year In Review publication at 2018 year in review.

Episode 17: You can’t manage what you don’t measure

By Podcasts

You can’t manage what you don’t measure. Agencies have been performing winter maintenance in one manner or another for a hundred years. Measuring how well we’ve been doing is a much harder proposition largely because no two storms are alike and the fact that they come and go so quickly and often overlap. Our two guests on this episode are no strangers to winter maintenance; Steve Lund is the State Maintenance Engineer for the Minnesota DOT and Caleb Dobbins is the State Maintenance Engineer for the State of New Hampshire. Both states have well developed programs to measure how well they perform winter service. Listen in as we talk about levels of service and performance metrics in use today and how they are used to manage winter maintenance operations.

Episode 16: Winter maintenance and the social sciences

By Podcasts

Why do travelers make the decisions they do during bad weather is a much more difficult question than many transportation agencies are geared up to answer.  The trinity of successful winter operations is the maintenance operation, the road weather, and the motorist.  Highway agencies have focused much resource on the maintenance operation and road weather but not so much on understanding why motorists do what they do.  

The National Academy of Sciences impaneled a project team to explore opportunities to integrate social and behavioral sciences in the weather enterprise during 2016-17.  I had the privilege and honor to serve on this panel co-chaired by Dr. William “Bill” Hooke, American Meteorological Society, and Dr. Ann Bostrom, University of Washington.  Our final report, Integrating Social and Behavioral Sciences within the Weather Enterprise, has implications for surface transportation.  

In this episode Dr. Hooke draws some parallels from his past experiences making the case that if we focus some more energy on the motorist we can have a better winter maintenance operation.

About our guest, Dr. William “Bill” Hooke:

Dr. Hooke has been involved in the atmospheric sciences since 1967 when he began working with the National Oceanic and Atmospheric Administration (NOAA). During his tenure at NOAA he was involved in many programs and research efforts.  In 2000 Dr. Hooke became a Senior Policy Fellow at the American Meteorological Society (AMS) and directed the Policy Program from 2001 to 2013.  Today he serves as the AMS associate executive director.  He authored the book: Living on the Real World: How Thinking and Acting Like Meteorologists Will Help Save The Planet and blogs at Living on the Real World.
