FERIC's Opti-Grade grading-management system can reduce grading costs by continuously measuring the condition of the road so as to identify sections that require the most maintenance and by concentrating maintenance efforts on those sections. Eighteen systems are already in service across Canada and the users report savings in grading costs on the order of 25%. Opti-Grade also lets managers determine the impact of the road's condition on travel speeds and justify the rehabilitation of problem sections.
