A route design decision support system was developed for maintenance engineers of the Indiana Department of Transportation (INDOT) to use in designing snow and ice control service routes. This system, known as CASPER - Computer Aided System for Planning Efficient Routes - incorporates a multiple objective heuristic optimization procedure to identify routes that have excellent serviceability and efficient resource usage. Routes designed using CASPER were placed into service and carefully evaluated by INDOT maintenance officials. The evaluation showed a significant improvement in network service and, at the same time, a 10 percent reduction in the size of the service fleet required. Cost savings to date are conservatively estimated at $5 million and are expected to exceed $14 million projected over a 10-year period when the system is implemented statewide.
