Maintenance Standards Snow and Ice Committee Report on Snow and Ice Formula

摘要

The first objective of the study was to establish whether or not Mn/DOT was providing the public with the proper level of snow and ice service. As a result of a public survey and the Commissioner's Staff review, a policy guideline was set for the level of service of snow and ice removal which was to stay at the current level or slightly below. The second objective then was directed at studying the current formula factors and considering new ones which would result in maintaining the policy guideline. Factors studied included, AADT Classification Ranges, Truck Speed, Cycle Times, Coverage Time, Workers per Truck, Spare Trucks, Interchanges, Absenteeism, and Functional Classifications. Accordingly, a new formula was developed and implemented.
