Clear Roads TAC Meeting
The Clear Roads Technical Advisory Committee met September 11-12 in Pittsburgh. Minutes are posted on the Meetings page.

Clear Roads Salt Manual Featured in APWA Reporter Magazine
The best practices manual on salt procurement, storage and application developed through a recent Clear Roads project was featured in the October 2016 issue of APWA Reporter magazine. See the article.

Clear Roads Survey Results Featured in Roads & Bridges Magazine
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

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.

Snow Removal Performance Metrics
Through a survey of more than 50 local, state and international transportation agencies, researchers found that agencies are shifting to outcome-based performance measures, rather than traditional input/output-based measures, for winter maintenance activities.

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.

New Resources

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.

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.

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.
