ABSTRACT
This chapter focuses on measuring and assessing the state of the driver by means of psychophysiological measures. It also focuses on measures of the cardio-vascular system and on brain activity measures. The nature of driving is changing as a result of an increase in the number of car users on the road, and the complexity of the traffic infrastructure. Measuring brain activity is the most direct measure of a driver’s cognition and is most sensitive to stages of information processing. Event related potentials are used to study effects on cognition and human information processing. The brain contains billions of neurons which process and transmit information by electric and chemical signalling. The chapter concludes with a discussion of the usefulness of the measures and the equipment coming onto the market to measure them efficiently.
