Welcome to the Pooled Fund Study Maintenance Decision Support System 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. The links at this website provide both general and specific information on current MDSS efforts in the United States. Although the focus of this site is to inform on the PFS MDSS efforts, links are also provided to appropriate websites of the Federal Highway Administration's Functional Prototype (FP) MDSS efforts.


Customer surveys indicate that winter driving conditions are the single most significant safety concern of travelers in northern states. Improvement of road conditions and winter highway safety has high financial impact to state transportation agencies and road users alike.

Indiana MDSS 08-09 Implementation Report

The Indiana Department of Transportation (INDOT) progressed from limited use of a MDSS in a Pooled Fund Study (PFS) environment to statewide implementation. The decision to implement statewide during the winter season of 2008-2009 was based on the savings reported by the maintenance units utilizing the program under the PFS and the fact that INDOT was facing declining revenues.
