Longitudinal motion cueing effects on driver behaviour: A driving simulator study

Driving simulator provides a safe environment to measure driving behaviour by using several sensory cueing systems that enhance the driver’s immersion in the virtual environment. The motion cueing system in driving simulator provides information on the vehicle movements with the use of motion cueing algorithms. The present study aims to investigate the effect of different motion cueing algorithms in a car following and braking task. The algorithms were developed in MATLAB-Simulink and were tested by 20 participants in a driving simulator. The simulator sickness questionnaire and session evaluation questionnaire were used to evaluate the simulator experience. The participants were able to rate the driving simulation experience based on the perceived motion. By investigating driver behaviour, Inter-vehicular distance has changed with motion scenarios. Indicators such as time to reaction, time to collision and effective braking time were examined with statistical test, but no difference was observed with different motion feedback. The study illustrated that different motion cues in driving simulator did not affect the cognitive and motor skills of the participants; however, it influenced the driver perception ofthe relative distance in the braking scenario. © 2019, Gioacchino Onorati Editore.
