Summary
This document describes the facilities and ongoing research initiatives of the Human Factors Laboratory within the Federal Highway Administration’s Office of Research and Development. The laboratory is designed to investigate driver capabilities and limitations to improve highway safety and efficiency, with a specific focus on accommodating the needs of an aging population and optimizing Intelligent Vehicle-Highway Systems (IVHS). The facility comprises three primary components: the SIGNSIM laboratory, the VIDSIM driving simulation laboratory, and a Graphics Center, alongside a field test vehicle currently under development. SIGNSIM is a static and partially dynamic research environment featuring sound and light-controlled rooms, a rear projection screen, and a tachistoscope. It utilizes a personal computer to control a random access slide projector with a variable aperture zoom lens, allowing researchers to present signs at various distances and precise timings. VIDSIM is a partially interactive driving simulation laboratory equipped with a driving buck and three widescreen projection televisions providing a 180-degree field of view. Upgrades to VIDSIM are intended to enhance the study of in-vehicle display technologies, including head-up displays and audible announcements, by coordinating them with real-world and animated driving scenarios. The field test vehicle, once completed, will feature an integrated PC data acquisition system and a reconfigurable dashboard to assess alternative instrument displays in normal traffic and proving ground environments. The Graphics Center supports these efforts by producing precisely defined stimulus materials and professional visual aids. Current research focuses on Advanced Traveler Information Systems (ATIS) and highway safety, specifically examining how information overload can diminish driving performance. One study investigated the effectiveness of perspective versus plan views in ATIS displays. In an initial experiment, older and younger drivers viewed slides of intersections and computer-generated displays in either perspective or plan view, tasked with identifying matching intersections. Results indicated that subjects were slightly more accurate in identifying intersections presented in the plan view. Furthermore, subjects, particularly older drivers, strongly preferred the plan view over the perspective view. Follow-up research using dynamic driving tasks is planned. Another research initiative explores the relationship between driver spatial ability, age, display type, and navigational performance. Since reading ATIS route guidance involves similar abilities to map reading, the study aims to determine how individual differences in spatial ability affect performance. The goal is to provide recommendations for in-vehicle display designs that account for these individual differences, thereby creating safer and more efficient systems. The overarching objective of the laboratory’s work is to ensure that new highway safety countermeasures and IVHS technologies are designed with careful consideration of user characteristics, particularly as the number of older drivers increases significantly in the coming decades.
Key finding
Subjects were slightly more accurate in identifying intersections presented in the plan view and strongly preferred this format over the perspective view.
