Workload of using a driver assistance system

The driver assistance system (DAS) is a driver-cooperative type system developed to reduce driver's workload and enhance driving safety. It was verified that the driver's workload is reduced when using the DAS with integrated lateral and longitudinal control, as well as the operational load, driver's heart rate and reaction time. In this report, driver's vital reaction such as the electromyography and the electrodermal activity were measured using an actual vehicle with the DAS in order to verify the influence on driver's workload. The DAS was also verified to decrease the driver's workload in view of the vital reaction.
