Abstract

<p>The effects of tree aroma on an automobile driver's wakefulness and active safety (e.g., keeping the appropriate time headway to the preceding vehicle) were investigated using a driving simulator. In this study, the supplying condition of Alpha-Pinene, that can minimize the olfactory stimulation of the driver and also can increase the effects on active safety, was investigated. Six different supplying conditions including two olfactory levels and three levels of supplying time (15s, 30s, 60s) were evaluated. It was clarified that supplying the aroma with short supplying time and high olfactory level, for instance, the supplying time span; 15 and the olfactory level; 4 (0: no odor, 5: intensive odor) is effective to satisfy above two conditions. The positive effects on these were continued for 5 minutes after one shot of supplying the aroma. It can be said that the intermittent supply in this condition and 5 minutes time cycle is one of the optimized supplying sequence.</p>
