Key result
Driving with an adaptive cruise control (ACC) system resulted in less active frontal lobe function compared to driving without ACC.
Why the study?
Does driving with adaptive cruise control (ACC) reduce frontal lobe brain activity in car drivers?
Does driving with adaptive cruise control (ACC) reduce frontal lobe brain activity in car drivers?
A proposed fNIRS signal processing method demonstrated that driving with adaptive cruise control reduces frontal lobe activity.
The aim of this study is to propose a method for analyzing measured signal obtained from functional Near-Infrared Spectroscopy (fNIRS), which is applicable for neuroimaging studies for car drivers. We developed a signal processing method by multiresolution analysis (MRA) based on discrete wavelet transform. Statistical group analysis using Z-score is conducted after the extraction of task-related signal using MRA. Brain activities of subjects with different level of mental calculation are measured by fNIRS and fMRI. Results of mental calculation with nine subjects by using fNIRS and fMRI showed that the proposed methods were effective for the evaluation of brain activities due to the task. Finally, the proposed method is applied for evaluating brain function of car driver with and without adaptive cruise control (ACC) system for demonstrating the effectiveness of the proposed method. The results showed that frontal lobe was less active when the subject drove with ACC.

TSUNASHIMA et al. (2009) studied Healthy subjects (car drivers) (n=9). Adaptive cruise control (ACC) system vs. Driving without ACC was evaluated on Frontal lobe brain activity. Driving with an adaptive cruise control (ACC) system resulted in less active frontal lobe function compared to driving without ACC.
