Clear Roads has just published its 11th Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 39 states for the 2024-2025 winter season. The spreadsheet includes all submitted data, as well as calculated statistics, winter severity index data, and a United States map that displays many of these metrics. … Read more

To help winter maintenance managers understand how sunlight affects melt rates, prioritize vegetation management, and communicate the benefits of roadside vegetation management to the public, this Clear Roads project produced a vegetation management guide.
Clear Roads has prepared a listing of technical sessions and posters related to winter maintenance that were presented at the 2026 Transportation Research Board Annual Meeting. The list includes links to more than two dozen papers and posters on a wide range of winter maintenance topics, including materials, equipment, technology, and performance management.
This Clear Roads project developed a tool that states can use to quantify the economic value of their snow-and-ice programs.
In this Clear Roads project, researchers developed metrics for comparing the two different forms of salt and conducted a variety of tests to measure their performance.
Real-time information about a pavement’s surface can help transportation agencies ensure roads have adequate traction and salt is applied only where it’s needed. This Clear Roads project evaluated roadway grip data as a viable source for informing winter maintenance operations, and developed models that use the data to identify the need for salt applications.
Clear Roads held its fall business meeting last month in Bloomington, Minnesota from September 16-18.
The Mechanical Rocker Test method, originally developed by Nebraska DOT more than a decade ago, was validated through Clear Roads research project 18-06 as a low-cost and repeatable method for determining the efficacy of liquid deicers. As a result of this work, all transportation agencies can objectively compare deicers on the market.
This recently completed Clear Roads synthesis project surveyed member states and other winter maintenance professionals and reviewed relevant literature to help transportation agencies implement effective policies and best practices for properly managing video and image data.
