This study evaluated whether a driver's intention to comply with a stop sign, and/or negotiate a turn, or proceed on a straight path could be predicted through the identification of patterns in driver input to vehicle primary controls. Driver input to primary controls was assessed during intersection approach, according to type of intersection maneuver. Control input patterns, relative to intersection arrival, will be used to identify effective timing of driver alerts and warnings regarding potential hazards at an intersection. The results of this study will support the development of countermeasures to prevent or reduce the severity of intersection crashes.

This paper discusses a top-down analysis methodology for the design, development and evaluation of advanced technological systems like those being considered for Free Flight, the Advanced General Aviation Transport Experiment (AGATE), or the High Speed Civil Transport (HSCT) program. In order to ensure a safe and efficient introduction and integration of those technologies, it is generally accepted that human factors engineering concerns must be raised and addressed from the beginning and throughout the research and development cycle. History indicates that human factors engineering concerns were normally addressed too late, contributing significantly to the well known “automation problem” in commercial aviation. In response to the potential for negative side effects advanced technology design guidelines have been developed. This paper focuses on one such guideline concerning sound systems engineering principles.

The Naval Biodynamics Laboratory (NBDL) has collected a database which describes human dynanic responses for −X acceleration exposures as a function of mass distribution variations of the head. Kinematic responses were measured on subjects with, (a) no mass addition; (b) with a helmet and weight-carrier mass addition; (c) and with the helmet and added weights symmetrically located with respect to the mid-sagittal plane of the head. The total mass addition to the head with the weights was approximately 30 percent. The helmet and weights were positioned with reference to the head anatomical coordinate system for each subject, with mass moments of inertia and variations in center of gravity then being determined. This paper compares responses both as a function of a mass distribution parameters and as a model to simulate the observed responses.

Automotive and aircraft interior designers have common concern with the proportion of user population accommodated with safety and full capability. Traditional design methods are shown to result in inadequate population accommodation for cockpit designs. An alternative method, Computerized Accommodated Percentage Evaluation (CAPE), is reviewed and cockpit CAPE models are described. This overview is used as a framework for consideration of potential for CAPE automotive models. It is concluded that a CAPE model for automotive vehicle interiors can be readily developed; and the Edwards et al Cockpit Assessment of Reach (CAR) model should be considered for the base of such a model.
