Clear Roads Survey Results Featured in Roads & Bridges
The Clear Roads annual survey to collect state winter maintenance data and the first year of the survey results were featured in an article in the September 2016 issue of Roads & Bridges magazine. See the article.

Recent Research Results

Synthesis Reports
Clear Roads has published two new synthesis reports. Effective Snow and Ice Personnel and Equipment Management for Storm Activation explores how state DOTs determine when to activate and deactivate winter maintenance crews, and Accuracy of Deicer and Abrasive Material Application Equipment examines state DOTs’ practices for calibrating their deicer application equipment.

Synthesis reports

Utilization of AVL/GPS Technology: Case Studies
Researchers profiled six state DOTs that use AVL/GPS in winter maintenance fleets. These case studies provide guidance for successful implementation, and can serve as templates to help agencies get the best value out of different levels of AVL/GPS applications.

Training Videos on Liquid-Only Plow Routes
This project created two videos that explain the benefits of liquid-only plow routes, describe how and when to use them, and outline the steps to implement a program. The videos are designed to help state DOTs garner support for and accelerate the implementation of liquid-only plowing.

Emergency Operations Methodology for Extreme Storms
Based on six case studies, researchers found that agencies with effective response plans for severe winter weather employ a transportation emergency management office, facilitate interagency cooperation, and embrace technologies for tracking and reallocating equipment.

Reducing Fatigue Among Snowplow Operators
Researchers sought to identify equipment-related factors that cause driver fatigue in snowplow operators. Recommended cost-effective solutions to help reduce driver fatigue included installing an audio player, dimmable interior lighting and snow deflectors.

New Resources

Snowplow Operator and Supervisor Training
This project developed a comprehensive snowplow operator and supervisor training program that provides flexibility for states to modify or update the content as needed. The 22-module program covers equipment, materials, techniques and procedures. Project details.

National Survey Compiles Third Year of Winter Maintenance Data
We’ve published our third Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 37 states for the 2016-2017 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 2014-2015 and 2015-2016 survey and displays averages and changes across winter periods.

Winter Maintenance at TRB
We’ve published our annual compendium of papers on winter maintenance that were presented at the 2018 Transportation Research Board Annual Meeting. The 2018 compendium includes abstracts for 19 papers grouped into six categories, covering a wide range of winter maintenance issues.

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 2017-2018 survey are now available.

Cost-Benefit Toolkit
This web-based toolkit takes the guesswork out of evaluating winter maintenance investments by facilitating cost-benefit analysis for 21 different winter maintenance materials, equipment and methods. There are also training materials and a user’s manual to get you started.
