New Clear Roads Research: Evaluating Indoor Automated Stockpile Measurement Systems

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 range of existing and emerging approaches to measuring indoor stockpiles, including automated and semi-automated systems using LiDAR, photogrammetry, surveying, acoustic sensing, and drone technology.
