Recent Research Results

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

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.

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.

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 2016-2017 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.
