Analysis of Students' and Tram Drivers' Body Ratios in Order to Simplify the Control Panel Design

Abstract

A total of 10 anthropometric measures were taken from a sample of 21 male tram drivers of ZET Zagreb, from a sample of 39 male students of the University of Zagreb, as well as from a sample of 48 female students of the University of Zagreb, out of which the mean arithmetic values of body segment ratios were determined. According to the scientific findings that body height decreases with age, male tram drivers were divided by age into three groups. Some of the calculated mean arithmetic values of body segment ratios h i /h for individual anthropometric measures h i in relation to the body height h have been compared with theoretical values of body ratios calculated by harmonic analysis by Zerderbauer and Muftić and the golden section, and it is obvious that there are no big differences in values. Body ratios h mdr /h and h ndr /h can be used for simplified calculation of anthropometric measures h mdr and h ndr only by knowing the value of body height h, during the control panel design in tram cab or train cab, because body ratios h mdr /h and h ndr /h do not depend on gender, age and occupation for adult respondents from Croatia.
