EVALUATION OF ODOT ROADWAY/WEATHER SENSOR SYSTEMS FOR SNOW AND ICE REMOVAL OPERATIONS. PART I, RWIS

This object of this report was to help the Ohio Department of Transportation determine the best way for serving the state's winter maintenance needs, focusing on how many and what kind of road weather information systems (RWIS) stations to deploy. The project involved a literature review, several field visits with winter maintenance personnel in Ohio, other states, and Switzerland. In addition, a survey was conducted of winter maintenance personnel nationwide, as well as a product review. The report also discusses lifetime cost estimates for RWIS, deployment and implementation plan considerations and Ohio RWIS deployment plan recommendations and conclusions. A bench test of pavement sensors is included in Part II as a separate document.
