Project Number: Clear Roads 05-02/WisDOT 0092-06-21
Start Date: October 2005
End Date: September 30, 2008
Investigator: Blackburn and Associates

Problem
Although ground speed control has been used on snow plow and salt spreader trucks in place of manual spreaders since the mid-1990s, the accuracy of the equipment has never been determined.

Objective
Document controller settings, actual salt usage and prewetting rate information from trucks with various types of controller units during winter storm events.

Expected Results
Guidelines to help snow plow operators establish and maintain accurate calibration of ground speed controllers, resulting in reduced salt usage and improved efficiency.
