This report documents a study which sought to determine the current eye height distribution among passenger cars and the eye height and field of vision among trucks. This was accomplished by a comprehensive literature review of eye height studies; a field study of eye height distribution among the most popular makes of passenger cars of 1975-76; a field study on the field of vision among trucks; and interviews with representatives from the major American automobile manufacturers. The study found that there had been a slight decrease in eye height among passenger cars within the last 15 years. The study further revealed that there were no significant differences between th eye height distribution of passenger vehicles as stated in the literature and those used in the pilot study. The field studies determined the automobile mean eye height of the sample cars to be 3.69 feet (1.12 m) and the 15th percentile to be 3.49 feet (1.06 m) while the sampled truck mean eye height was determined to be 8.41 feet (2.56 m) and 7.80 feet (2.39 m) for the cab-over-engine and the cab-behind-engine configurations, respectively. Based upon the driver eye height dimensions and trend into the late 1970's as determined from published literature and validated in this study, and the desire to safely design for the great majority of drivers, the report recommends an eye height dimension of 3.45 feet (1.05 m) be used for highway design. /FHWA/
