Mortimer, Rudolf G. (2012): How a Video Record of a Driver's Forward View Made a Difference in the Human Factors Analysis of a Traffic Crash. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 710-714.

“Modern vehicles are equipped with various recording devices that can aid in accident reconstruction and human factors analyses. One example is the fitting of video recorders in buses and trucks. In one such case a bus ran into the underside of an overturned semi trailer that was blocking both lanes of an interstate highway in darkness. While a first review of the case suggested that the bus driver would not have been able to avoid the collision, that opinion was reversed when the video recording became available of the view ahead of the bus in the 6 seconds before the crash.”

Mortimer, Rudolf G., Casey, Steven, Dingus, Thomas, Schmidt, Richard and Sind-Prunier, Paula (2011): "Unintended Acceleration": Human Factors Engineering Issues and Solutions. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 1924-1927.

“In the first few months of 2010 the news media reported numerous instances of "unintended acceleration". Vehicles were recalled because a floor mat was thought to be snagging the accelerator pedal. However, some vehicles that had gone through the recall still experienced unintended accelerations, indicating that the problem also lay elsewhere. In the 1980s there were recalls of over 100,000 Audi vehicles with automatic transmissions in which drivers had reported unintended accelerations. Earlier cases had also been reported (Mortimer, 2011), so the issue is an old one. As a result of such runaway events, primarily in vehicles with automatic transmissions, automakers equipped them with shift-interlocks, so that the vehicle could not be moved into either a forward or reverse gear after starting the engine unless the driver's foot was depressing the brake pedal. About 83% of unintended acceleration events were reduced by this device (Schmidt, 1993), confirming the role of driver pedal misapplication when starting out. Other studies found that drivers show pedal confusions also when the vehicle is under way. Those events are not reduced by the shift-interlock. Rogers&Wierwille (1988) found about 0.2% of foot movements resulted in a "serious' pedal misapplication error in a simulator. Tomerlin&Vernoy (1990) found that 1 of 169 of their drivers stepped on the accelerator instead of the brake and continued to do so in a driving test. Such results show that drivers "frequently" make pedal errors, especially when considering that there is about one brake application per mile (Mortimer et al, 1970) in the U.S. The panel members will discuss the human factors issues that cause pedal misapplication in various types of vehicles and their frequency, including crashes that result. The thrust of the discussions will be on how our present knowledge can be used to reduce these hazardous events and to discern what additional information is needed to solve the "unintended acceleration" problem.”

Mortimer, Rudolf G. (1995): General Aviation Airplane Accidents Involving Spatial Disorientation. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 25-29.

“National Transportation Safety Board accident data for 1983-1991 were used to compare those general aviation accident cases that involved spatial disorientation (SD) with all others. About 2.1% of general aviation airplane accidents involved SD. Those accidents were associated with low ceilings, restricted visibility, precipitation, darkness and instrument flight conditions. Pilots in certain professions, particularly those in business, were more involved in SD accidents. Pilots in SD accidents were more often under pressure, fatigue, anxiety, physical impairment and alcohol or drugs. The pilots' total and night flying experience were inversely related to involvement in SD accidents. Spatial disorientation accidents accounted for a small number of crashes, but they were very severe -- fatalities occurred in”

Mortimer, Rudolf G. (1993): The High-Mounted Brake Lamp: A Cause Without a Theory. In: Proceedings of the Human Factors and Ergonomics Society 37th Annual Meeting 1993. pp. 955-959.

“Studies are described that formed the basis for the Federal high mounted brake light standard and some that have been done since. One purpose of this paper is to show how some details of the new Standard are hard to derive based on the underlying research. In addition, there was no adequate theory of driver performance upon which the standard was based. Although experimental”

Mortimer, Rudolf G. (1989): Older Drivers' Visibility and Comfort in Night Driving: Vehicle Design Factors. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 154-158.

“Older persons are a growing proportion in the population, among drivers and those involved in traffic accidents. Changes in visual abilities of older persons are pertinent to night driving glare. Vehicle headlighting and related factors are reviewed which affect visibility and comfort in night driving. Older drivers, in particular, would be aided at night by: increasing the reflectivity of objects, limiting the mounting height of headlamps, appropriate reflectivities of mirrors for control of glare, automatic headlamp alignment, automatic headlamp cleaning and beam patterns that emphasize glare control.”
