Evaluation of Indoor Automated Stockpile Measurement Systems


Accurately measuring indoor salt stockpiles has traditionally been a challenge for transportation agencies. Clear Roads is interested in examining a range of existing and emerging approaches to indoor stockpile measurement, including systems using LiDAR, photogrammetry, surveying, acoustic sensing, and drone technology. In particular, Clear Roads is interested in automated or semi-automated systems that have the capability to measure a stockpile, and transmit the data to a central location.


The goal of this project was to conduct a data-driven evaluation of currently available automated or semi-automated indoor salt stockpile measuring systems in order to improve agencies’ day-to-day management of their salt stockpile inventories.


By automating this process, states can improve their inventory management and minimize costly rush orders of salt.
