The Michigan Department of Transportation (MDOT) recently completed architectures and pre-deployment plans for five of the state's seven regions. The paper provides benefit-cost calculations for two weather-related deployments, Road Weather Information Systems (RWIS) and Maintenance Tracking using Global Positioning System (GPS) for Maintenance Vehicles and Snowplows. The potential benefits of RWIS combined with Maintenance Tracking are: crash reduction during adverse weather, and operating cost savings through more efficient use of winter maintenance resources.
