ABSTRACT
In the paper, results of some driver reaction time research are presented. In the research, typical device for psychological studies of drivers was used – so named reflexometer MCR. The reaction time of the driver, using controllers (keypads) of the panel, is assessed in response to stimuli in the form of sound and light signals. Results of measurement for above 100 drivers are presented. The surveyed group of respondents consisted of men aged from 19 up to 64. So called simple reaction as well as complex reaction is analyzed. A main criterion of analysis is driver age (age of respondents). This article presents a statistical analysis of the received results (reaction times). The results are presented in the form of histograms and statistical parameters of the distributions obtained (median, mean value, standard deviations, extreme values, and quantiles of order 0.1 and 0.9). They are presented for separate four age classes.  In case of simple reaction examination, it has additionally been presented how a type of stimulus: light or sound stimuli affect the reaction time of respondents. The presented results are one of the effects of research project no N509 016 31/1251.
