| Abstract | This report discusses the effectiveness of using variable message signs (VMSs) and in-vehicle traffic advisory systems (IVUs) on a mountainous pass (Snoqualmie Pass on Interstate 90 in Washington State) for changing driver behavior. As part of this project, variable message signs and variable speed limit signs have been placed along a 61 km segment of I-90 between North Bend, WA, and Cle Elum, WA. The study area is the region where I-90 passes over the Cascade mountains through Snoqualmie Pass. The signs, which were implemented during the winter of 1997-98, provide speed limit, weather, and roadway information to motorists with the intention of reducing the number and severity of accidents at this location. |
