ROAD WEATHER INFORMATION SYSTEMS - INTELLIGENT TRANSPORTATION SYSTEM APPLICATIONS BY THE NEVADA DEPARTMENT OF TRANSPORTATION

Beginning in 1983 the Nevada Department of Transportation (NDOT) developed several automatic motorist warning systems to address localized potential hazardous driving conditions involving freezing temperatures, high wind, poor pavement condition and low visibility. These applications vary from a simple system that monitors temperatire inside a tunnel and activates a warning sign to a complex application that monitors several meteorological parameters and issues various appropriate warnings and automatically reduces the speed limit. The development of the road weather information system (RWIS) has provided many opportunities to expand and enhance intelligent transportation sustems (ITS) associated with motorist warnings. This paper will describe the evolution of the technology and it's application in western Nevada from the beginning in 1983 through our current projects which began operation in October 1997.
