ABSTRACT
Communication can contribute to behavioural change. The effectiveness of communication strategies depends on many factors. Theories of social influence can assist road authorities in making behavioural interventions more effective. Consequence interventions are based on the assumption that behaviour can be changed by changing the positive or negative consequences of behaviour, and some behaviour analysts consider consequences to be the main determinant of voluntary behaviour. This type of intervention is generally effective in promoting behaviour change. The three basic consequence strategies are: penalties, rewards and feedback. Antecedent interventions influence one or more elements in the environment prior to the performance of behaviour. The most common antecedent strategy is the provision of information. Another approach is the use of modelling. Intervention techniques are more effective in the extent to which they specifically address those factors that contribute substantially to the particular problem behavior.
