Decrease of vigilance caused by sleep deprivation affects driving behaviour and results in delay in reaction and loss of vehicle control. This behaviour leads to increase of road accidents. The effect is typical at long commutes and monotonous roads with tedious landscape and is especially noticeable in so called vulnerable diver population groups, namely novice and senior drivers, shift and overtime workers. Prediction of such a behaviour shall contribute to vehicle safety systems through improvement of driver-car interface for prevention of sleepiness at wheel and decrease number of accidents caused this factor, where timely detection of a driver loss of vehicle control is crucial. Current study represents an experimental research on driving simulator with sleep deprived subjects from two age groups (senior, experienced drivers and young, novice drivers) and compares the vehicle control and lateral position ability based on analysis of vehicle lane position, deviation of speed, lane departure time and lane departure area in subject’s two state (fresh, rested state and induced sleep deprived state), while performing a car following task with speed-change cycles. |
