Using Automated Vehicle Location (AVL) and Global Positioning Systems (GPS) technologies throughout the year can help justify the expenses of purchasing and installing them in maintenance vehicles and training staff to use them. Many AVL/GPS systems have applications that extend beyond winter maintenance practices, increasing the benefits and value of these technologies. This Clear Roads … Read more
Many state and local transportation agencies with winter maintenance programs purchase their road salt before the winter season to secure the best prices and assure availability. However, measuring and monitoring the quantity of salt in widely distributed stockpiles—including many sites without regular staff on-site—can be both challenging and time-consuming. This Clear Roads project examined a … Read more
Clear Roads has published its eighth Annual Survey of State Winter Maintenance Data, which compiles data on winter resources, materials and costs from 36 states for the 2021-2022 winter season. The interactive spreadsheet-based tool includes a United States map that displays many of these metrics.

On October 13, 2022, members of the Lake George Association in upstate New York hosted their annual Salt Summit to discuss strategies and technologies for reducing road salt. Clear Roads member Joe Thompson of New York State DOT spoke at the event, sharing highlights of the in-progress Clear Roads research project investigating ways agencies can … Read more
As temperatures drop, sodium chloride loses its deicing power. Depending on conditions, adding more salt to a roadway may be ineffective and wasteful. To help maintenance managers make the most of their stockpiles and keep roads clear, this Clear Roads research project investigated how salt behaves at different temperatures and concentrations. With a new tool … Read more
New tools and training materials developed by Clear Roads are featured in an article in the October issue of APWA Reporter. Designed to help state and local transportation agencies save time and money on their winter maintenance operations, these new resources resulted from three recent Clear Roads research projects: CR 19-03: Measuring the Efficiencies of … Read more
