The document summarizes Finland's Traffic Safety 2025 research programme and an analysis tool called ONHA for accident databases. The research programme involves multidisciplinary traffic safety research with a focus on technical solutions to help achieve national goals of fewer than 250 road fatalities by 2010 and 100 by 2025. ONHA is an internet-based tool that allows users to analyze numbers, circumstances, locations, and parties involved in accidents while protecting personal privacy. It enables grouping, filtering, producing tables and graphs from the accident data. A short demonstration of ONHA's capabilities to select and analyze data on accidents involving drunken drivers from 1995 to 2009 is provided.

5. Analysis tool for accident data, ONHA - contents An Internet-based programme has been built up to analyse: - numbers of accidents and their consequences - circumstances of accidents and their locations - involved parties and persons in them - NO RISK FOR PERSONAL PRIVACY With ONHA one can: - group and crop the data - show trends and background variables - produce tables and figures (cross-tabulation!) - make statistical comparison of distributions
