Title:

Evaluation of Computer-Generated Routes for Improved Snow and Ice Control

Abstract:

A route design decision support system was developed for maintenance engineers of the Indiana DOT to use in designing snow and ice control service routes. This system known as Computer Aided System for Planning Efficient Routes (CASPER) incorporates a multiple objective heuristic optimization procedure to identify routes that have excellent serviceability and efficient resource usage. An evaluation showed a significatnt 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 dollars and are expected to exceed 14 million dollars projected over a 10-year period when the system is implemented statewide.
