This paper analyzes the responses from two nationwide surveys designed to obtain user information requirements for the design of advanced traveler information systems (ATIS) and commercial vehicle operations (CVO) with respect to commercial system operators (dispatchers) and commercial vehicle drivers. A total of 673 returned surveys (348 dispatcher surveys and 325 commercial driver surveys), were used in the analysis. Mathematical models were developed, using a binomial logit to predict whether the commercial driver or dispatcher would use an intelligent transportation system, and an ordered probit to estimate the importance of information (i.e. route and navigation, roadside services, personal communication and road and traffic information) to be provided by in-vehicle information systems. The results of this study provide guidelines for the design of information systems and help define informational requirements for users of ATIS/CVO.
Evaluation of the Potential Benefits of Advanced Traveler Information Systems
This paper evaluates the potential travel time savings from Advanced Traveler Information Systems (ATIS) that provide drivers with travel time and routing information. We classify ATIS in various levels based on the type of information they use to generate guidance and the timing of the dissemination of the generated guidance to drivers. We present a case study that examines the potential travel time savings of ATIS as well as the implications on travel time variability and reliability and the sensitivity of the results to the accuracy of the information, using real-world
Travelers' preferences for in-vehicle information systems: An exploratory analysis
Transportation Research Part C: Emerging Technologies, 1995
A sample of travelers' preferences toward in-vehicle traffic information systems was undertaken and appropriate statistical models were estimated. Specifically, ordered logit and regression analyses were conducted to quantify travelers' ratings of the importance of in-vehicle system attributes, and the distance ahead that they prefer to be notified of various types of information provided by in-vehicle systems. Model estimation results show that travelers' socioeconomics, habitual travel patterns, commute congestion levels and attitudes toward in-vehicle technologies are significant determinants of travelers' importance ratings and the preferred distance ahead of in-vehicle system information. These model results provide important information for both marketing and design of in-vehicle information systems.
Quality of information given by advanced traveler information systems
Transportation Research Part C: Emerging Technologies, 1996
A number of studies have evaluated the services provided by Advanced Traveler Information Systems [ATIS] under the assumption that information supplied to drivers would be, in some sense, perfect. However, lack of sufficiently useful data and system design constraints can lead to information that is less than useful to the ATIS user. This paper examines the effects of such imperfection through a simulation-based model that was applied over a part of a large metropolitan area. The model has four basic components: (i) an ATIS structure (that specifies the information-gathering, processing and disseminating aspects of the system) (ii) traveler behavior (iii) network characteristics and (iv) vehicle movement logic. Using a 'yoked driver' concept, a number of different route guidance strategies are examined. The results indicate that some strategies that would appear to be desirable are not so. Conversely, under high-congestion situations, strategies can be constructed that come close to 'rectifying' completely the effects of information imperfection. Overall the paper reiterates the potential of ATIS if information-giving strategies are designed carefully.
Awareness and Utilization of Advanced Traveler Information by Active Seekers
Transportation Research Record: Journal of the Transportation Research Board, 2015
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 informatio...
Effectiveness of Traveler Information Tools
2008
Abstract: The North Carolina Department of Transportation (NCDOT) sponsored research aimed at enhancing the department's ability to assess the effectiveness of traveler information tools. The NCDOT has and will continue to make investments in Intelligent Transportation Systems (ITS) that fall under the heading of Advanced Traveler Information Systems (ATIS). It is critically important for the NCDOT to be able to assess the impacts, especially the network performance benefits, of candidate ATIS investments in order to ...
Behavioral issues in the design and evaluation of advanced traveler information systems
Transportation Research Part C: Emerging Technologies, 1993
Decisions about implementing Advanced Traveler Information Systems (ATIS) should be based on the individual and social benefits expected from such technologies, which will be strongly dependent on the ways travelers respond to these new information sources. This paper explores the behavioral issues important to understanding traveler reactions to ATIS; it discusses evaluation strategies, including stated preference methods and observation of revealed behavior in laboratory simulations and field tests with various degrees of control and complexity. Advantages and disadvantages of different approaches are reviewed, and the experimental design challenges of site selection, recruitment of test subjects, and measurement of behavior are explored.

The purpose of Task A was to conduct a literature review of human factors-applicable articles associated with Advanced Traveler Information Systems (ATIS) and ATIS-related commercial vehicle operations (CVO) systems. Specifically, Task A was to assess existing human factors guidelines to determine their applicability to ATIS systems and identify research gaps that would be filled to establish complete and comprehensive ATIS guidelines. As with any literature review, the conduct of Task A was treated as a foundation for subsequent tasks. The duration of Task A (3 months) was such that some of the literature of interest could not be obtained prior to publication of this document. Thus, the literature review does not, in effect, end with this report.
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1993
This paper describes the outcome of a comprehensive literature review specifically conducted to assess research relevant to the design of advanced traveler information systems (ATIS) for automotive and commercial vehicle use. The goal of the literature review was to identify existing human factors guidelines applicable to the design of ATIS and gaps in the research precluding the development of comprehensive human factors guidelines for ATIS applications. A summary of ATIS research findings and research gaps is presented. Through presentation of both research findings and research gaps, it is hoped that interest will be sparked and focus will be provided for researchers in this growing application of human factors. Given the criticality of ATIS applications (both in terms of driver safety and public acceptance) and the visibility that will be provided to the human factors community from participation in ATIS design, human factors research leading to comprehensive and usable guidelin...
