RFPs Posted for New Research Projects
Clear Roads is currently soliciting investigator proposals for four new research projects. For all projects, the deadline to submit proposals is September 7, 2022. See the RFP page for details.
Clear Roads TAC Meeting
The Clear Roads Technical Advisory Committee held its spring meeting via videoconference April 12-14. Minutes are posted on the Meetings page.
Clear Roads Research in the News
—”Steering Clear of Crashes“: Clear Roads’ safe and defensive driving training materials were featured in the October 2021 issue of APWA Reporter. The training was also featured on Episode 57 of AASHTO’s SICOP Talks Winter Ops podcast.
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
Expanded Application Rate Guidance for Liquid Deicers
New guidelines provide application rates for salt brine and brine blends across a range of field conditions, including lower pavement temperatures.
Measuring the Efficiencies of Tow Plows and Wing Plows
Researchers developed a decision support tool that lets state DOTs compare the efficiencies and life cycle costs of using different snowplow types on specific plow routes.
Tools for Improving Snowplow Route Optimization Projects
This project developed guidance on the technical requirements and key considerations for undertaking a plow route optimization program, including a contracting language template to help agencies build route optimization RFPs.
Adding Camera Systems to Snowplows
Taking into account the variety of available cameras, installation configurations and uses for aftermarket camera systems, researchers compiled recommendations for states wanting to initiate or expand camera use on winter maintenance vehicles.
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.
Pre-wetting Methods and Procedures
Researchers detailed the current state of the practice for pre-wetting salt and other solid materials, capturing details on equipment, methods, materials and application rates. The project also identified a list of preliminary recommendations to help agencies get the most benefit from pre-wetting.
Advanced Technologies for Winter Operations
Researchers developed a guide to implementing eight emerging and recently developed winter maintenance technologies. By understanding the options and their benefits, agencies can make informed decisions about which technologies to invest in.
Entry-Level CDL Training Materials
A new federal rule is changing how transportation agencies train equipment operators who need to obtain or upgrade a commercial driver’s license (CDL). To help agencies comply with the new requirements, Clear Roads has developed entry-level CDL training materials for instructor-led classroom and behind-the-wheel training. Available as a free download for any state or local public agency, the training materials include a fact sheet and timeline to help agencies achieve compliance. See the project page and fact sheet.
National Survey Compiles Seventh Year of Winter Maintenance Data
We’ve published our seventh Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 36 states for the 2020-2021 winter season. The spreadsheet includes all submitted data as well as calculated statistics and a United States map that displays many of these metrics. New this year is the inclusion of statewide averages for winter severity. The spreadsheet also includes data from the previous six surveys (winters 2014-2015 through 2019-2020) and displays averages and changes across winter periods.
Winter Maintenance at the 2022 TRB Meeting
We’ve published a list of technical sessions and papers related to winter maintenance that were presented at the 2022 Transportation Research Board Annual Meeting. The list includes more than 15 papers and posters, with links to abstracts and presentation materials.
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.
