This article deals with the analysis of dependence among the driver's bioelectrical impedance status and surrounding effects, which can negatively influence the driver's attention and thus lead to decrease the driver's safety while driving. Bioelectrical impedance was measured using AD5933 circuit and two conductive silicon electrodes placed on the steering wheel. The measurement was performed on several drivers of various age at a different daytime and in a different grade of traffic. Hereafter acquired data were statistically analyzed and significant values, which affect the measured driver's impedance with given probability were identified. Based on results of the analysis, we proposed an algorithm of software for detection the events that could possibly decrease the driver's safety. The driver's impedance data acquired from the steering wheel is used as a control variable for the detection algorithm.
