Maddox, Michael E., Fitch, Greg, Kiefer, Aaron, Mortimer, Rudolf and Muttart, Jeffrey (2012): Panel Discussion -- Factors related to perceiving the relative speed of leading vehicles in high-speed rear-end crashes. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 690-694.

“Forensic human factors practitioners are often engaged to offer expert opinions in cases involving rear-end collisions. Such collisions represent approximately 25% of all automobile crashes and have done so for many years. The sad fact is that people run into the backs of slow moving or stopped vehicles with a low, but persistent probability. According to the 100-car study, the probability is 1 in 1.84 million miles traveled (Americans drive a total of about 3 trillion miles per year). A number of researchers have examined the circumstantial and perceptual issues related to rear-end crashes in an effort to understand why drivers have such a difficult time perceiving the relative speed of leading vehicles. Results from these studies are often cited in expert reports and testimony. In particular, the 'looming threshold' established in these studies is sometimes used to establish the expectation of braking or steering responses. However, when reconstruction data are used to calculate looming thresholds, the values are usually much higher than those obtained in controlled studies. It is unclear whether these data represent the same phenomenon. The purpose of this panel discussion is to examine the breadth of data related to rear-end crashes and offer insight into the discrepancy between reconstruction and experimental results.”

Maddox, Michael E. and Kiefer, Aaron (2012): Looming Threshold Limits and Their Use in Forensic Practice. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 700-704.

“Rear-end collisions account for about one-third of all traffic crashes on a yearly basis. It has been apparent for some time that the key to perceiving a slower vehicle ahead of us as an imminent hazard, i.e., one requiring immediate action, is a sufficient rate of change of the visual angle of the lead vehicle. This is known as the 'looming threshold', among other things. A number of laboratory researchers have reported values of the looming threshold to be in the range of 0.003 radian/sec. Forensic practitioners routinely use elevated values of the looming threshold, e.g., 0.005-0.008, to account for the complexity of real-world driving tasks. However, only one source has used data from actual vehicle accidents to arrive at a looming threshold -- and that value, 0.0275 rad/sec, is an order of magnitude larger than that derived from laboratory studies. In this study, we examine a much broader range of real-world accident data to obtain an estimate of the reasonable upper end of the looming threshold. The results show a range of 0.0397 to 0.0117 rad/sec, for presumed perception-reaction times (PRTs) of 0.75 and 2.0 seconds, respectively. We discuss the implications for forensic human factors analysis of rear-end crashes.”

Maddox, Michael E. (1995): Providing Useful Human Factors Guidance to Aviation Maintenance Practitioners. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 66-70.

“The Aloha Airlines B-737 accident in 1989 prompted a general evaluation of aviation maintenance and inspection practices. A consistent finding from the Aloha analyses was that human-factors-related issues played a significant role in the accident. In the intervening period, the FAA Office of Aviation Medicine (AAM) has sponsored a wide-ranging, applied human factors research program. The Human Factors Guide for Aviation Maintenance (the Guide) is the primary vehicle for channeling the results of the AAM's research program into the aviation user community. This paper describes the development process of the Human Factors Guide for Aviation Maintenance. We include a discussion of how the existing base of research results has been made accessible and, more importantly, usable to aviation maintenance supervisors and inspectors. We also describe the considerations related to widely disseminating the information and guidance contained in the Guide. We believe this to be the first time that detailed human factors guidance from such a broad topical range has been tailored to a particular, applied, user domain.”

Maddox, Michael E. (1994): Introducing a Practical Human Factors Guide into the Aviation Maintenance Environment. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 101-105.

“A safe and efficient air travel system depends on three elements; design, operation, and maintenance. The Human Factors profession essentially began and matured in the aviation environment. The aircraft cockpit and the skills involved in piloting have been the subjects of more human factors research than any other single topic. Likewise, the topic of aircraft design has been the beneficiary of many of the tools and procedures developed to embed human capabilities into products. The third component, maintenance, seems to receive attention only when it is shown to be a contributing factor in a mishap. In an effort to embed proper human factors principles in the aircraft maintenance environment, Congress, through the Federal Aviation Administration Office of Aviation Medicine (OAM), has mandated that more emphasis be placed on human factors in maintenance operations. A major product of this initiative is a Human Factors Guide, being developed to provide practical, useful, and usable guidance to supervisors and planners in the aviation maintenance industry. This paper describes the goals, form, and content of the new Human Factors Guide.”

Maddox, Michael E. and Turpin, James A. (1989): Design of a Consumer Computer Terminal for Automated Access to Overnight Delivery Services. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 465-469.

“Consumer product design is seldom approached in a truly systematic framework, especially in applied settings. Although most designers know about systems design techniques, real design projects usually appear to be driven by severe scheduling constraints, cost limitations, strongly held opinions on the part of management and designers, or all of these characteristics. There has also historically been friction between human factors professionals and industrial designers. The result is that most consumer products have not undergone a truly systematic process of design and testing. This paper describes a case study in which a real product with potentially significant financial impact has been designed and is being tested using a systematic process. More significantly, this product represents a collaboration among company management, human factors professionals, and industrial designers. The overall design and testing process is described. Results from several tests, successively increasing the fidelity of the test items, are presented.”
