Developing A System for Consistent Messaging on Interstate 80 Dynamic Message Signs Phase II

Traveler Information Systems, a part of the larger field of Intelligent Transportation Systems (ITS), were originally utilized in urban areas to reduce congestion. Traveler information has become increasingly important in rural areas, especially in areas with adverse weather conditions such as Wyoming. Dynamic message signs (DMS) are often used to provide information during a traveler’s trip. Current research literature does not contain guidance for the rural use of DMSs. This report analyzes the effectiveness of traveler information, with a focus on the use of DMSs on the I-80 corridor between Laramie and Cheyenne in southeast Wyoming, using several different methods including surveys of both frequent and random travelers and a statistical analysis of the correlation between speed, weather and DMS data. The current message decision system utilized by the Wyoming Department of Transportation (WYDOT) is also described and evaluated. This report is a continuation of an earlier effort on this topic. The Phase I report, “Developing Systems for Consistent Messaging on Interstate 80 Dynamic Message Signs ─ Phase I” (MPC-09-211A), can be found at www.mountain-plains.org.
