Benefit Summary HTML
This study tested the use of an in-vehicle traffic map device called TrafficGauge to determine the perceived and actual benefits of using in-vehicle freeway traffic congestion information in the Puget Sound region of Washington State. With assistance from the Washington State DOT (WSDOT) the University of Washington recruited participants from around the region to test the in-vehicle devices. Participant usage was monitored for a period of six months and customer satisfaction survey data were collected from November 2007 to May 2008 to evaluate user experience, and collect information on frequency of use and benefits gained.
