Welcome to the Pooled Fund Study Maintenance Decision Support System Operations Website

This Pooled Fund Study (PFS) is the result of a multi-state effort to bring about an operational Maintenance Decision Support System (MDSS) for state transportation agencies.

In order to provide safe transportation to motorists, state transportation agencies must apply effective highway maintenance treatments appropriate to a wide range of winter conditions. Maintenance personnel must decide what treatments to apply, and when to apply them, based on their knowledge of current pavement conditions, current and forecasted weather conditions, as well as available maintenance techniques and resources. In large part, current decisions are based upon prior experience of maintenance personnel and supervisors.
