The ROSATTE project aims to establish an efficient and quality ensured data supply chain from public authorities to commercial map providers with regards to safety related road content. Figure 1 shows the involved entities at the three levels of data acquisition, exchange and integration and the anticipated dataflow.

Up-to-date safety attributes are needed by road authorities and for Advanced Driver Assistance Systems (ADAS). ADAS applications are commercial products that can contribute significantly to achieving objectives for reducing the yearly number of road fatalities on European roads by half in 2010. In this context, road signs like speed limits or other warning signs are considered road safety features. The information about these features is acquired, maintained and used by public road authorities within the EU member states for their internal duties. The idea of ROSATTE is now to make use of the information that anyway is available at the road authorities. Besides the exchange of full databases, special focus will be put on the exchange of new or changed data, so-called incremental updates.
The ROSATTE project intends to develop the enabling infrastructure and supporting tools that will ensure European access to road safety attributes including incremental updates. This infrastructure will facilitate administrative internal functions as well as supply of data to third parties e.g. for safety relevant services.
The IIGS mainly contributes to all project tasks related to data quality, i.e. quality management and validation of results.
Within this quality management concept, the IIGS developed and applied the test and validation methodology. With its help, the IIGS tested and validated all developed methods and tools within ROSATTE. The completeness, topological correctness and accuracy of the integrated features were of interest. It could be shown, that the developed data exchange infrastructure works with satisfying quality. However, the location referencing issue proved to be most critical and mainly influenced the integration completeness and correctness.
