National Survey Compiles Seven Years of Winter Maintenance Data December 29, 2021

Clear Roads has published its seventh Annual Survey of State Winter Maintenance Data, which compiles data on winter resources, materials and costs from 36 states for the 2020-2021 winter season. The interactive spreadsheet-based tool includes a United States map that displays many of these metrics.

New this year is the inclusion of statewide averages for winter severity. The tool includes seven years of data, and displays averages and changes across winter seasons. See the project page.

New Clear Roads Resource: Entry-Level CDL Training Curriculum December 2, 2021

For many transportation agencies, a new federal rule will mean changes to the way they train equipment operators who need to obtain or upgrade a commercial driver’s license (CDL). To help agencies comply with the new requirements, Clear Roads has developed entry-level CDL training materials for instructor-led classroom and behind-the-wheel training.

Available as a free download for any state or local public agency, the training materials focus on operators who are obtaining an initial Class B CDL, upgrading from a Class B CDL to a Class A CDL, or obtaining the hazardous materials endorsement for the first time. The materials include a fact sheet and timeline to help agencies achieve compliance by the February 2022 deadline.

For more information and to request the free materials, see the project page.

Clear Roads Research in the News October 19, 2021

As temperatures drop, industry magazines are turning their focus to winter maintenance. Clear Roads research features prominently in two of them this fall:

In preparation for the season, winter maintenance crews from across the country demonstrated their skills at the annual National Snow Roadeo in September, with a four-person team from the Idaho Transportation Department taking home the national team title. Congrats to all the winners!

New Clear Roads Research: Recruiting and Retaining Highway Maintenance Workers September 30, 2021

Finding and keeping skilled, dedicated highway maintenance workers has become increasingly challenging for state and local transportation agencies.

To help agencies navigate today’s employment landscape, a recently completed Clear Roads research project created a comprehensive guide of innovative, practical strategies for attracting and retaining new winter maintenance employees. Case studies cover recruitment programs, retention strategies, recruiting younger workers and those from underrepresented groups, and program improvements.

New Clear Roads Research: Pre-wetting Methods and Procedures August 2, 2021

Pre-wetting road salt helps keep the salt on the road’s surface, which makes winter maintenance more efficient and cost-effective. While pre-wetting practices are used by many agencies, they have not been extensively studied.

A recent Clear Roads research project took stock of the current state of the practice for pre-wetting salt and other solid materials, capturing details on equipment, methods, materials and application rates. Researchers also compiled a list of preliminary recommendations to help agencies get the most benefit from pre-wetting and identified areas for future study.
