Advanced traveler information systems (ATIS) are new to the state of Maine, and there are many unanswered questions about their effect on motorists. Dynamic message signs, variable speed limit signs (VSLS), and overheight vehicle detection (OHVD) systems are key components of ATIS and are the means through which motorists can be provided with en route information pertinent to their travels. Speed data were collected during inclement weather events to determine the effect of VSLS on traveler speed. Speeds were collected during storms of different intensities. The data suggest that motorists adjust their speed to conditions and what they think is appropriate. This finding is also supported by survey responses. The fact that motorists do not slow down to the posted speed could be partly because of the VSLS not being enforced. An OHVD system installed in Bangor, Maine, in August 2006 has shown potential, with no hits to the I-95 overpass since installation. Part of the study consisted of identifying and evaluating the institutional issues and barriers associated with intelligent transportation system deployment. These issues include long-term funding commitments for ATIS, acceptable messaging, integration of information databases, interagency coordination, enforcement, and education of the public.
