A recent survey is described in which a series of anthropometric measurements were taken which are related to automobile design. In the first phase of the research 1,000 seated subjects were used to obtain 22 static measurements, most of which were indexed to two different reference points, the SAE H point and the accelerator heel point. In the second phase of the research measurements of functional arm reach to 117 points within the seated workspace were obtained on 100 subjects. Examples of the static and dynamic data obtained are given in both tabular and graphic form. Discussions are included of the measurements taken, the reasons for their selection, the measuring techniques employed, the statistical analyses used, and the potential applications of the data.

HIGHWAY safety-an important problem in the truck and bus industries - is governed by many factors, one of the most important being the human element. This paper describes the Harvard School of Public Health research program concerning the human factor in vehicle design and operation. The project is Sponsored by the Commission on Accidental Trauma of the Armed Forces Epidemiological Board, Department of Defense; the National Association of Automotive Mutual Insurance Companies; the American Trucking Associations, Inc.; and the National Association of Motor Bus Operators. Some items of this investigation include the study of near accidents; detection of the accident repeater; personal adjustment and morale of drivers; human body size and capabilities with relation to controls, instruments, seats, and vision; the effects of temperature, ventilation, noise, and vibration; and desirable safety features to protect the operator if an accident occurs.

The use of ergonomics in the design of vehicular equipment is presented. It is proposed that the wider use of the principles and methods of this discipline might aid in the more effective integration of the driver and his equipment. It has been shown that the effectiveness of any man-machine system depends upon the integration of the biological characteristics of the operator with the mechanical design of the equipment and working areas. The initial phase of a program in ergonomics should always consist of an advance analysis of the equipment, including a survey of the nature of the task, the work surroundings, the location of controls and instruments, and the way the operator performs his duties. In highway safety the application of human engineering principles has been shown to be of great importance in the design of windshields, rear view mirrors, and vehicle lighting, and other visual aids to the drivers.
