[Efficacy evaluation of preventive interventions: experience and proposal for road accident prevention strategies].
OBJECTIVE
To supply the local administrators with a tool for a preventive evaluation of the improvements in road safety brought about by specific interventions which are planned. It is one of the first Italian experiences in the area.


METHODS
The database consists of the accidents occurring in three municipalities of the province of Modena characterized by accidents of high severity. Models were used to simulate changes related to possible interventions. The goodness of the model-based estimates has been evaluated after the implementation of interventions.


RESULTS
Scenario analyses indicate which actions are most effective. Preliminary estimates of efficacy suggest a good agreement with model-based forecasts.


CONCLUSIONS
Results encourage the adoption of methods of preventive evaluation of the efficacy of preventive actions.
