Summary

This report, produced by Battelle for the Federal Highway Administration in 1995, addresses the need to define precise development objectives and performance requirements for Advanced Traveler Information Systems (ATIS) and Commercial Vehicle Operations (CVO). As part of a broader initiative to create human factors design guidelines for Intelligent Vehicle-Highway Systems (IVHS), the study aims to establish a baseline of the transportation community’s conceptualization of these systems. This baseline is intended to support subsequent research tasks, including functional definitions, comparable systems analysis, and task analysis, ensuring that system designs enhance driver acceptance and usability. The methodology combined a comprehensive literature review with primary data collection from 49 individuals representing government agencies, research and development sectors, and private industry. These participants were selected through an iterative process involving IVHS America technical committees and operational test efforts such as Pathfinder and TravTek. Data were gathered via semi-structured interviews, which typically lasted two to four hours, and included facility tours and product demonstrations. Participants also completed ratio-scale rating questionnaires to assess the relative importance of various ATIS subsystems and development objectives. The analysis involved summarizing interview notes and written materials, alongside statistical analysis of questionnaire responses to determine mean importance ratings and confidence intervals. The findings categorize ATIS capabilities into four primary subsystems: In-vehicle Routing and Navigation Systems (IRANS), In-vehicle Motor Services Information Systems (IMSIS), In-vehicle Signing Information Systems (ISIS), and In-vehicle Safety Advisory and Warning Systems (IVSAWS). The report identifies five core development objectives: decreased traffic congestion, improved safety, increased and higher quality mobility, improved environmental quality and energy efficiency, and improved economic productivity. For each objective, the study details specific performance measures and requirements for institutional, private vehicle, and commercial vehicle applications. Additionally, the authors developed 12 preliminary scenarios for private vehicles and 14 for commercial vehicles to illustrate operational capabilities and projected benefits across different system configurations, ranging from infrastructure-based to vehicle-based architectures. The significance of this work lies in its provision of a structured framework for the ongoing development of IVHS technologies. By documenting the range of operational capabilities and prioritizing performance requirements based on stakeholder input, the report facilitates the transition from conceptual design to specific functional definitions. It supports the standardization of system architectures and ensures that future human factors research is grounded in the actual needs and expectations of the transportation community. This foundational data is critical for guiding the design of interfaces and information subsystems that effectively meet both institutional goals and consumer demands for safety, efficiency, and mobility.

Key finding

The study established a baseline set of performance requirements and importance ratings for ATIS and CVO subsystems across five development objectives based on expert consensus from 49 industry and government participants.
