The project is complete.  The research identified an approach for estimating the benefits of winter maintenance operations in terms of increased safety, reduced travel time, and reduced fuel usage and discussed the limitations of the approach.  In addition, data from a state highway agency was used to illustrate applicability of this approach for estimating the benefits accrued from performing winter maintenance operations. The final report has been provided to AASHTO staff and the chair and members of the AASHTO Highway Subcommittee on Maintenance; it also avaiilable on the AASHTO Highway Subcommittee on Maintenance website.(NCHRP Staff: Amir N.
