Read carefully below case study. (Solve Question 4 and 5 using below case study) Monitoring System Gives Highway Crews the Edge in Winter Maintenance A State of the art road weather information system provides the Minnesota Department of transportation with timely, accurate information on road and weather conditions. The result is safer travel during winter months. The Challenge Battalions of snowplows and sand trucks attack Minnesota's highway and streets each winter. The crew can't be ever where at once,however.The Minnesota department of transportation (DOT) needed a way to determine when and where winter maintenance crews, equipment and materials should be deployed to be most effective. The DOT thus decided to implement a Road Weather Information system (RWIS). The technology, enhanced and evaluated under the Strategic Highway Research Program (SHRP), Provides accurate, up to the minute information on road and weather conditions, helping the state ensure safe travel during the winter months. Putting the RWIS to the test Minnesota DOT has so far setup 17 RWIS Stations, Clustered around Duluth and the twin cities areas. The stations consist of a number of sensors that collect information on weather and pavement conditions. These data are relayed to a central monitoring station where they are used to enable more effective scheduling of work crews and equipment. The DOT reports that the RWIS is working well. RWIS gives an early morning when pavement condition become critical and provides weather forecast that allow crews to act before the first icy sports formed on the road way," says Edward maintenance operation research coordinator for DOT. RWIS data also help DOT crews optimize their use of deicing metarial. Information from the sensors helps crew chiefs know the proper amount of chemical to apply, Edward says, by using chemicals only where needed, agency saves money and protects the environment. The economic benefits are enormous . Once study cocluded that by improving the efficiency of Minnesota DOT's winter maintenance efforts, an RWIS system would more than pay for itself- with returns on investment ranging from 200% to 1300%.
