Why the study?
Working conditions for vehicle drivers are a health and safety concern, necessitating methods for hygienic and physiological assessment of real visual loads on car drivers.
A method using publicly available devices to simultaneously record visual load and heart rate in car drivers showed moderate correlation, potentially useful for assessing working conditions and preventing fatigue.

Working conditions for drivers of vehicles are a health and safety concern. For hygienic and physiological assessment of real visual loads on a car driver, a method for simultaneous recording of information visual load (IVL) and heart rate has been developed and tested in situ. We used publicly available devices — a car DVR and a wrist pulse monitor. An example of timesynchronized recordings of the IVL stream and pulse is given. The efficiency of the method is shown and the correlation of video fragments and pulsogram to R = 0.4 (moderate on the Cheddock scale) is established. The systematization of factors of working conditions (external and internal in cabin at the workplace) that affect the perception of IVL is outlined. The results of the work are applicable for the hygienic assessment of the working conditions of vehicle drivers, when IVL is a leading factor in working conditions and workload, in order to prevent fatigue and traffic accidents.
