The introduction of electronic aids in traffic offers special opportunities for alleviating tasks of both public bodies and individual road users. However, the introduction is often problematical. In this context potential and existing applications are discussed in a functional classification, based on the traffic safety process. Perception, decision-making and action are dealt with for each phase of the process. The discussion gives rise to conclusions, relating to the stimulation of new developments, to applied research, to broader application, and to optimisation. Finally, demands prior to instrumentation and implementation of electronics in traffic are considered, among them possibilities and restrictions related to electronics themselves, aspects of information transfer to and information processing by road users, and the impact on traffic task performance.
