The measures need to be included in national and local road safety programmes and fully funded. Targets should be set ‘bottom-up', that is based on the modelled potential to reduce deaths and serious injuries of the interventions planned for introduction or intensification of enforcement. Preferably, a target should be expressed in terms of an absolute number of casualties (deaths or seriously injured) to be saved rather than in terms of a rate (e.g. number of deaths per 100 000 population).
