During the last two decades, the systematic efforts for gathering and harmonising road accident data at the European level have led to a significant upgrade and enhancement of the CARE database. Moreover, important data collection and harmonization efforts have provided very useful results as regards exposure data and safety performance indicators; however, the availability, completeness and level of harmonization of this data varies significantly. At the same time, additional data and related information sources have been established at EU level, including in-depth data, behaviour / attitudes data, programmes and measures data, social cost data etc., mainly in the framework of European research projects. However, these data sources are still not of sufficient comparable quality, are still not sufficiently linked, and the aggregate data are not always accessible. Finally, an important amount of national data remains unexploited at the European level. Consequently, there is a clear need for the consolidation of the various data (at least at an aggregate level) into an integrated system, a data warehouse. This will allow not only for better integration of the various data assembly processes, but also for the provision of a complete set of data services, with full documentation of the data and their sources, in order to support road safety knowledge and the related decision making. This data warehouse will be developed as a complete working tool for road safety stakeholders, for which not only a full description of the structure, format and content will be designed and specified, but also the related content will be provided, consisting in fact of a new system with road safety related data/information in aggregate form. The objective of the DaCoTA WP3 is the development of the DaCoTA System, a road safety data warehouse as a comprehensive and integrated system with aggregate data and information consolidating, organising and making available all existing data and information, necessary for the support of the decision making. The proposed DaCoTA pilot system is destined to serve as example for the further enhancement of the European Road Safety Observatory (ERSO), as new structures and features were tested during the development procedure and new data and knowledge have been assembled and have become available for incorporation into the existing ERSO. The establishment of this solid but easily accessible, integrated road safety system allows for road safety policy and decision making to use a complete set of aggregate road safety related data (road accident data, risk exposure data, safety performance indicators, indepth data, health indicators/data) and information (programmes, measures, legislation, social cost, behaviours/attitudes, regulations). During the first phase of the DaCoTA WP3, the description of the Data Warehouse /DaCoTA System structure, format and content was designed and specified, based on previous work undertaken within the SafetyNet project, taking into account new, additional outcomes and needs from all DaCoTA project WPs. Additionally, a first set of national and international data and information was defined and gathered through appropriate templates, along with the related explanatory meta-data and the related links and was included into a pilot system that will be further improved and enhanced during the second phase of the project. During the second and last phase of the DaCoTA WP3 the DaCoTA System’s structure, and format were finalised and its content was updated according to the data/information gathered. The DaCoTA System is available in pilot phase since July 2012 and in full operation since October 2012 at the following internet address: http://safetyknowsys.swov.nl. It has been presented to the European road safety community before and during the DaCoTA project Conference in Athens in November 2012. By the end of the DaCoTA project all the contents of the DaCoTA System will be available at the respective website. (Author/publisher)
