Internalisation of external costs of transport has hitherto been focused on distance-based charges. While this may affect driven distance, it has no influence on driving behaviour. The authors demonstrate in this economic field experiment that it today is possible to observe drivers actual behaviour with GPS technology and thus possible to refine the economic incentives. To ensure participation, they give drivers a monthly bonus, which is reduced according to the speed behaviour. They make the experiment with two different bonus levels and two different price levels. Their pricing scheme significantly reduces the proportion speed violations of the participants and we conclude that this is a possible way to improve car drivers speed behaviour. (Author/publisher)
