Research Pays Off: Implementing a Winter Maintenance Decision Support System: Indiana Department of Transportation's Process, Success, and Savings

In 2002, the Indiana Department of Transportation (DOT) joined the South Dakota, North Dakota, Minnesota, and Iowa DOTs in a pooled fund study to develop a maintenance decision support system (MDSS). The study now has 15 state DOTs participating, with support provided by Meridian Environmental Technology, Inc. As part of the pooled fund MDSS effort, Indiana DOT conducted field trials for three winters, starting in 2005-2006, adding routes and improving communications processes each year. A significant finding was that participating subdistricts reduced salt use from 10% to 30% compared with the use in neighboring areas. Indiana DOT developed and provided training on the use of the MDSS to winter maintenance personnel throughout the state. Implementation of the MDSS statewide has generated a significant net savings in the first year, and Indiana DOT anticipates a continued accrual of benefits annually, as the MDSS continues to be integrated into standard operational procedures.
