Abstract
Human factors is designing to match the capabilities and limitations of the human user. The objectives of this human- centered design process are (1) to maximize the effectiveness and efficiency of system performance, (2) to ensure a high level of safety, and (3) to maximize user acceptance. These objectives are achieved by systematically applying relevant information and principles about human abilities, characteristics, behavior, and limitations to specific design problems. This handbook provides a source document for Automated Highway System (AHS) designers that will facilitate a human-centered design process for the AHS. (Author/publisher)
