Abstract
The primary responsibility of drivers is to use the information around them to control their vehicles in terms of speed and position. With future Transport Telematics systems comes the potential for increasing the amount of information presented to the driver. This information could relate to the primary task of vehicle control, or could relate to secondary or tertiary functions. The design of such systems to minimise confusion and maximise usability is a complex challenge. Of the errors which cause road traffic accidents, the clear majority have a human component. Findings from human factors research should be integrated into the design process. One method of accomplishing this is to develop standards and guidelines to aid the designers.
