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 measurimg their physiological reactions. Heart rate, brain waves (Beta-waves) and galvanic skin response clearly changed under driving conditions that increased the drivers 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.
