This report discusses the effectiveness of using variable message signs (VMS) and in-vehicle traffic advisory systems (IVU) on a mountainous pass (Snoqualmie Pass on Interstate 90 in Washington state) for changing driver behavior. As part of this project, variable message and variable speed limit information were placed along a 61-km segment of I-90 between North Bend, Wash., and Cle Elum, Wash., where I-90 passes over the Cascade mountains through Snoqualmie Pass. The signs, which were implemented during the winter of 1997-98, provided weather and roadway information to motorists with the intention of reducing the number and severity of accidents.
