Available in PDF, EPUB and Kindle. Book excerpt: This study measured direct and rearview-mirror glare illuminances produced by low-beam headlamps in a sample of 22 passenger vehicles. The glare illuminances were measured for 12 common glare situations that were defined by a full factorial combination of three scenarios (oncoming driver, center rearview mirror of a preceding driver, or driver-side mirror of a preceding driver one lane to the right), two longitudinal distances (25 m or 50 m), and two vertical locations (glared vehicle being either a car or a light truck/van/SUV). The measurements were made outdoors at night on asphalt pavement. The median illuminances ranged from 0.5 lux for an oncoming driver of a light truck/van/SUV at a distance of 50 m, to 3.4 lux at the driver-side mirror of a preceding car at 25 m one lane to the right. (These values do not take into account window transmittance or mirror reflectance.) The ratios of the maxima and the minima measured for each of the 12 glare situations were large, ranging from about 5:1 to 36:1. The median actual illuminances were compared to the median expected illuminances based on a recent, laboratory-measured, representative sample of U.S. low-beam patterns, taking into account the possible effects of dirt, voltage, misaim, and pavement reflectance.This analysis indicates that the actual illuminances could be very well modeled using the laboratory-measured beam patterns and assuming a linear relationship between the light output of clean and dirty headlamps. Additional analyses evaluated the relationships between headlamp mounting height and glare illuminance.

Available in PDF, EPUB and Kindle. Book excerpt: The potential glare from rearview mirrors was quantified in simulated encounters using data on the locations of mirrors and headlamps, and on the photometric output of low-beam headlamps. This was done for two classes of vehicles (passenger cars, and light trucks and vans [LTVs]) in the roles of the vehicle subject to the glare and the vehicle producing the glare. The results indicate that, in many encounters with glare vehicles to the rear, there will be a substantial disparity in glare, both among vehicles of different classes and among different mirror locations on a single vehicle. The main reason for this is the strong role of mirror height in determining how much a mirror is exposed to the lower, and therefore stronger, portion of a low-beam light pattern. There is substantially greater potential for high glare values on the mirrors of passenger cars versus LTVs. and on the driver-side mirror versus the center rearview mirror on all vehicles. With upward misaim of headlamps, these disparities are increased, as is the absolute level of potential glare. The relatively low potential for glare on the center mirrors of LTVs will often be compounded by the low transmittance of privacy glass on those vehicles.The present results have implications for where glare light should be sensed in order to control automatic anti-glare mirrors. However, specific recommendations should incorporate two additional considerations: (1) the geometry of a given vehicle, including the actual heights of the rearview mirrors and how the potential fields of view of those mirrors are affected by opaque parts of the vehicle, and (2) quantification of the exposure to glare that vehicles experience in actual traffic, including the frequencies at which glare vehicles are encountered in the fields of view of the individual mirrors.

This book was released on 2008-04-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: In terms of simple and complex systems, it is a whole new world out there. At the initial publication of this book, fourteen years ago, the web was in its infancy, DVDs did not exist, cell phones were few and far between, and the information superhighway was just a blip upon the horizon. If you used the terms "social engineering," you were most likely a political scientist, and if you were "phishing" you might be listening to a rock band. The second edition of a bestseller, Human Factors in Simple and Complex Systems provides the necessary understanding of the breadth and depth of human factors issues that influence the design, implementation, and evaluation of products and systems. Emphasizing the close relationship between basic theory and application, the authors delineate a framework for the research process, present an integrated view of the current state of knowledge, and examine how these factors can be applied to system design. The new edition addresses such concepts as situation awareness and highlights topics of interest, with a special focus on computer applications and human-computer interaction. See what’s new in the Second Edition New topics, such as situational awareness, that capture the tremendous changes in human factors and ergonomics Tightly integrates basic research and application, strengthening the link between knowledge and practice Each chapter includes a separate box that discusses a topic of current interest related to human interaction with computers and recent technology Demonstrating a general approach to solving a broad range of system problems, the book provides coverage of the theoretical foundation on which the discipline of human factors is built. Structured around human information processing, it covers the full range of contemporary human factors and ergonomics, then shows you how to apply them.
