  • Abstract:
    This paper studies the context in which Seattle-area travelers make decisions about whether or not to consult traveler information sources, and subsequently whether or not to change their travel plans in response to the information they receive. Its starting point is the basic premise that traveler information, by providing advance knowledge of travel conditions, can help travelers save time, money, and frustration. Moreover, Seattle is precisely the sort of congested metropolitan area where information can be most useful, and it offers a range of freely available information sources in various media. Interestingly, however, the use of traveler information is fairly uncommon, with travelers seeking information on only 10 percent of their trips and making a change in response to information on less than 1 percent of their trips. In other words, Seattle-area travelers seem to show relatively little interest in services that provide many potential benefits at little or no direct cost. This paradox is examined using data from a broad-based travel diary survey. Six factors affecting the decision to use traveler information are analyzed: the broader regional context, awareness levels, trip characteristics, information quality, the presence of delays, and the availability of alternatives. This paper finds that all of these factors contribute to an environment in which travelers confine their information acquisition efforts to a narrow subset of their daily travel. It also finds that insufficient data quality acts as a barrier to greater information use, which is consistent with user evaluations of information systems.
