Recent Research Results

Snowplow Route Optimization
A review of snowplow route optimization projects showed that detailed data about a plow route network and close collaboration between route modelers and the operators who drive the routes are critical factors in an optimization project’s success.

Plug-and-Play Initiative: Phase II
Researchers identified data types that will enhance a plug-and-play protocol for data transmission between winter maintenance equipment and central offices or other point locations. An open protocol will allow interoperability between different vendors’ equipment and facilitate data sharing among agencies.

GPS/AVL Guidance
Researchers developed an equipment guide that describes how winter maintenance agencies are currently using GPS/AVL technology. The guide serves as a resource for agencies that are looking to implement or expand their use of GPS/AVL.

New Resources

Winter Maintenance at TRB
We’ve published our annual compendium of papers on winter maintenance that were presented at the 2017 Transportation Research Board Annual Meeting. The 2017 compendium includes abstracts for 22 papers grouped into seven 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. Read more.

National Survey Compiles Second Year of Winter Maintenance Data
We’ve published our second Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 34 states for the 2015-2016 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 survey and displays averages and changes across the two-winter period.

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.
