Evaluation of the TowPlow for Caltrans Operations

Caltrans is responsible for the safe operation of many mountainous highways and must ensure that they remain open and passable throughout the winter. Certain critical highways carry heavy seasonal recreational traffic as well as high volumes of truck traffic. Caltrans spends approximately $25 million annually on snow-fighting operations, which involve a fleet of over 800 snowplows, an array of additional equipment, and approximately 2,600 employees. Caltrans has been actively searching for safer and more efficient methods for winter snow-fighting operations. As such, Caltrans requested that the Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center configure, procure, and deploy two Viking-Cives TowPlow systems and conduct an extensive evaluation to determine the most beneficial configuration and application of TowPlow technology for Caltrans. This report covers procurement of an initial TowPlow trailer system, development and testing through two winter seasons, the procurement and development of a second TowPlow trailer system, and discussion of particular modifications needed to allow for safe and legal operation on California highway. Due to three consecutive exceptionally light snow seasons in California that coincided with the project's testing period, an evaluation of TowPlow performance in conventional Caltrans snowplowing operations has not been possible. As an alternative, a detailed structure of data collecting capabilities and analysis tools has been developed to evaluate plowing performance for future snow seasons. This document covers research through June 30, 2015.
