| Abstract: | A qualitative evaluation was made on how a newly-developed semi-automatic transmission system “ESCOT” (Easy, Safe Controlled Transmission) reduced the mental work load on drivers, by measuring their physiological reactions. Heart rate, brain waves (β-waves), and galvanic skin response clearly changed under driving conditions that increased the driver's mental work load, such as when shifting gears, braking and turning at a crossing. From these measurements, a mental work load index was empirically derived. The average mental work load index for long-distance driving was reduced by about 30% when driving a tractor equipped with the ESCOT system compared to the conventional 12-speed manual transmission. |
