“…Stated preference questionnaires require respondents to indicate how they would react to various scenarios or the degree of value placed in the topic of interest by offering a choice between limited, mutually exclusive alternatives. Stated preference surveys have been used by researchers to investigate the impact of ATIS on trip changes (1,4,(18)(19)(20), in various nonrecurrent traffic conditions (21), on acceptance of transit (22), and in emergency situations (23). The primary limitation of stated preference surveys is the overstatement of travel behaviors (2,4).…”

Intelligent transportation systems (ITS) have been deployed worldwide as a cost-effective means to mitigate concerns about congestion, safety, environment, and other issues. Researchers commonly use questionnaire surveys to gauge the public's response to the success of ITS deployments in achieving the stated ITS goal of improving customer satisfaction as well as the other goals of strengthening transportation safety, mobility, efficiency, productivity, energy, and environmental efforts. To differentiate itself from previous research, this study sought to identify how Michigan travelers who actively sought travel information perceived benefits from advanced traveler information systems (ATIS). Toward this objective, a revealed preference questionnaire survey was developed and linked on the Michigan Department of Transportation's foremost online hub for publicly available travel information, Mi Drive. The survey included questions about the typical sources of travel information, frequency of information use, tendency to alter predeparture travel behaviors as a result of information, and similar topics. The study used ordered logistic regression modeling to uncover some key findings, which included the influence of time of year, resident location, and travel information affinity on active ATIS users' perception of ATIS. Discovery of such relationships could enable transportation agencies to enhance the marketing and operation of ATIS services such as Mi Drive and thus strengthen the systemwide benefits experienced by motorists.

“…However, as far as known, no research on distracting effects of these messages has been carried out (SWOV, 2012). Limited research has been done on possible beneficial effects of road safety messages on VMS (Jamson & Merat, 2007;Schroeder & Demetsky, 2010;Tay & de Barros, 2010). All compared the display of blank VMS screens with road safety messages in either quasi-experimental field studies or driving simulator studies.…”

Road authorities struggle with the question whether variable message signs (VMSs) should exclusively be used for traffic management or could also be used to display traffic-irrelevant messages, such as mottos or commercial advertisements. The current study assesses behavioural responses to a critical route instruction displayed on the same VMS that previously displayed a variety of traffic-irrelevant messages. For this, thirty-two participants were divided between a control group and an experimental group (the advertisements group). In a driving simulator, all were familiarised with the same route by driving a VMS-equipped motorway nine times. For the advertisements group, up to drive 8, this VMS displayed various advertisements. Whereas for the control group it was blank. In the 9 th drive, the VMS displayed a critical detour message for all participants. This critical route instructioninforming drivers to take the nearest exitresulted in compliant driver behaviour in the advertisements group. In addition, they only reduced speed marginally to increase the time to process the VMS text. The control group, on the contrary, displayed a much sharper speed reduction; though the instruction only moderately altered motorway exit behaviour. What is more, the 31% (n = 4) of the advertisements group who complied with the critical route instruction subsequently failed to recall this message (recalling an advertisement instead). In conclusion, this study provides evidence that displaying traffic-irrelevant messages on VMSs might not interfere with traffic management; provided the format of said messages is in accordance with ergonomic VMS guidelines as used in this study. It is proposed that due to repeated exposure to various VMS texts, reading the sign has been practised to the extent that little to no conscious deliberation was required. As a result, recall of what was seen, proved to be an inadequate proxy for assessing driver behaviour. This study shows that conscious attention might not be a prerequisite for compliance. Furthermore, it suggests that continuous variability in objects in the traffic environment may become part of a subconscious monitoring process, as long as they have been sufficiently practised.
