Clear Roads Research in the News
Two Clear Roads projects are in the news this fall:

—”Steering Clear of Crashes“: Clear Roads’ safe and defensive driving training materials are featured in the October 2021 issue of APWA Reporter.

—”Can You Hold the Salt?“: Clear Roads research on alternative methods for deicing is spotlighted in the September 2021 issue of Roads & Bridges.

Clear Roads Training Materials Featured in APWA Reporter
Clear Roads training materials were featured in the October 2019 issue of APWA Reporter magazine. The article highlights Clear Roads’ video training on plowing intersections and interchanges, video training on using liquids for anti-icing and deicing, and instructor-led training modules for snowplow operators and supervisors.

Clear Roads Snowplow Training Featured in Roads & Bridges Magazine
Clear Roads’ modular, customizable training materials for snowplow operators and supervisors were featured in the February 2018 issue of Roads & Bridges magazine. See the article.

Recent Research Results

Recruiting and Retaining Highway Maintenance Workers
Researchers created a comprehensive guide of innovative, practical strategies that state and local transportation agencies can use to attract and retain highway maintenance workers. Case studies cover recruitment programs, retention strategies, underrepresented groups, younger workers, and program improvements.

New Resources

Winter Maintenance at the 2021 TRB Meeting
We’ve published a list of technical sessions and papers related to winter maintenance that were presented at the virtual 2021 Transportation Research Board Annual Meeting. The list includes more than 20 papers and posters, with links to abstracts and presentation materials.

National Survey Compiles Sixth Year of Winter Maintenance Data
We’ve published our sixth Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 36 states for the 2019-2020 winter season. The spreadsheet includes all submitted data as well as calculated statistics and a United States map that displays many of these metrics. It also includes data from the previous five surveys (winters 2014-2015 through 2018-2019) and displays averages and changes across winter periods.

Training Materials for Plow Operators
Clear Roads continues to add to its comprehensive suite of training materials for snowplow operators and supervisors. Free for any agency to download, the materials include:

—Clear Roads’ flagship 22-module Snowplow Operator and Supervisor Training.

—New modules on defensive driving and safe driving for operators.

—Videos on clearing challenging interchanges.

—Videos on using liquid-only plow routes.

Clear Roads Is Now Overseeing the Qualified Products List (QPL)
For many years, the Qualified Products List maintained by the Pacific Northwest Snowfighters association has helped agencies identify deicing chemicals and additives that meet established standards for corrosiveness and impact on the environment. As the QPL continues to grow, Clear Roads will be overseeing product testing and administration for the list, which is now called the Clear Roads QPL. See the QPL page and Letter to Vendors.

Product Experience Survey Results
Every year, Clear Roads members complete a survey on the results of winter maintenance materials and equipment testing that their agencies have conducted during the previous winter. The informal survey is not a scientific evaluation, but serves as a tool for states to share their experiences. Results of the 2020-2021 survey are now available.
