Summary
This document presents preliminary human factors guidelines for the design of Automated Highway Systems (AHS), developed by the Federal Highway Administration to support human-centered design practices. The research addresses the critical need to integrate human capabilities and limitations into system design to maximize performance efficiency, ensure safety, and improve user acceptance. The authors identify a significant gap in engineering education and practice, noting that less than 21% of engineering publications from 1938 to 1987 adequately addressed human factors, leading to systems prone to human error. The guidelines aim to correct this by providing designers with systematic principles for specifying functional requirements, selecting controls and displays, and designing driver-system dialogues. The methodology involves a comprehensive examination of existing handbooks, human factors engineering texts, and analyses from current research projects. The report is structured around a defined system design process that includes identifying mission requirements, determining system functions, allocating tasks between humans and automation, and specifying interface philosophies. The guidelines are organized into two volumes; Volume I provides specific design recommendations, while Volume II details user-system transactions across three distinct AHS scenarios: Free Agency/Self-Contained, Barriers on the Highway with Grouped Vehicles, and Segregated Highway with Individual Vehicles. The authors utilized these scenarios to derive functional requirements and evaluate how different levels of automation and highway configurations impact user interactions. The findings are presented as detailed specifications and recommendations for various interface elements. Volume I covers population characteristics, including anthropometric data for workspace design, and provides general and specific guidelines for controls such as joysticks, pushbuttons, rotary selectors, and voice recognition systems. It also offers extensive guidelines for electronic visual displays, including CRTs, LCDs, Head-Up Displays, and auditory displays, specifying minimum character sizes, spacing, and legibility requirements. Additionally, the report outlines principles for labeling, workspace layout, and user-computer dialogues, including menu selection and error handling. Appendix tables provide tradeoff analyses and priority rankings to assist designers in selecting appropriate controls and displays for specific tasks. The significance of this work lies in its provision of a standardized source document for AHS designers, facilitating a design process that explicitly accounts for human limitations. By applying these guidelines, designers can reduce the potential for human error and lower training costs. The report emphasizes that while these are preliminary guidelines, particularly in the area of operational guidelines, they represent a necessary step toward ensuring that automated highway systems are safe and usable. The document serves as a practical tool for engineers to make informed decisions about interface philosophy and component selection, ultimately aiming to enhance the effectiveness and safety of automated transportation systems.
Key finding
