The purpose of this research project is to assemble a new EU-based framework for the collection and dissemination of road accident and injury data and associated information, in order to create a road safety Observatory at European level. The project includes several basic types of road safety data needed to support an efficient road safety policy, including national level data, exposure information, road safety performance indicators, in-depth data and information on safety related rules in the Member States. The safety data gathered will be harmonized at several levels, inserted in linked databases and exploited in road safety analyses. These analyses aim to demonstrate the appropriate methodologies, as well as the added value of detailed outcomes based on linked databases.
